“. . . anyway, from – Philip Glass, Beats Antique, Chopin, Clifford Brown, Max Roach, Booker Ervin, Sarah Vaughan, Ojos de Brujo, Jessica Williams, Tape Five, The Grassy Knoll, to Tool – I’m having a fabulous time listening (we have a short summer in Alaska so I’m not supposed to be inside listening this much until winter) and many of my music loving friends have enthusiastically approved of my new audio related acquisition!!!“
“The PAP Classics’ are exceptional, great tone, sensational bass. Gave my subwoofer to my son, didn’t feel I needed it. Just writing a review now after spending 5 months with the Classic’s. Couldn’t be happier!
“I still have, use and enjoy the Quintet15’s a lot. To give you an idea, I go thru amps like nothing, but the speakers stay.”
” Just like everybody will write: I am shocked!!”
“I didn’t expect this experience, and it has caused me to reconsider what top end sound is about.”
” Well, I’m now the proud owner of these wonderful speaker! My god, how good does it get?!… The ease of how these speakers work, the soundstage, the naturalness has elevated my system to a level I never thought possible. Drums sound like drums, pianos sound like pianos, etc., etc., etc. I have to listen to my whole library again!”
” Within seconds both our mouths fell open in surprise. What a soundstage. And with what ease… I have heard many speakers over the years, ranging from $500 to $50,000, but these speaker are in a league of their Own. “
” I’ve heard some damn fine speakers make some damn fine sounds in my day, but these took this to a whole ‘nutha’ level. Every instrument and voice occupied and owned its own space in the given composition. It was truly remarkable… Imaging? In the room! And although there is always a “sweet spot” for best listening, from anywhere in the room, the impact and holographic presentation was palpable…”
“I love the speakers. Love them. I find them perfect for me… The flexibility inherent in the open baffle concept and your business model mean that this is the last and final speaker system for me. I wake up looking forward to exploring fascinating new sounds every day. Thank you!”,

“The Best Investment in my Life”
Email from 6 February 2022:
“For more than 4 decades I have been searching for a way to make music sound believable at home. I grew up with the sound of music instruments so that is my reference. Furthermore my parents took me to the Berliner Philharmoniker and the Wiener Philharmoniker both playing in their own concert halls. I grew up in Amsterdam so I frequently went to the Concertgebouw Orchestra playing in the Concertgebouw. As well as other famous orchestras, conductors and solo musicians performing in the Concertgebouw. End of my teens I met with a guy whom I still consider my best pal and he was and is totally into old style jazz and playing in a band. So then I visited a lot of jazz performances. Long story to make clear what my references are. I play classical music mostly large symphonic works, but also rock, pop and reggae and I prefer live recordings and to play them at realistic levels. Loud.
I will skip my history of audio equipment, but my last set of loudspeakers were a pair Harbeth 40.2 chosen for their tonal accuracy. I truly believed they would be my last pair. Being an early adopter of digital playback and, as soon as they became available, ripping techniques I have owned a lot of digital hardware. I ended up with a heavily modified dac with a tube output and capable of playing resolutions up until 96kHz from a dedicated NAS not connected to the network and I thought I was happy. Just enjoying music without the nagging feeling that I needed other equipment.
Then I made the mistake accepting a few invitations to listen to classical recording professionals explaining how they work and demonstrating their own work on unaffordable systems. After a few of these sessions the nagging feeling had returned. Especially because they used Merging hardware with a network connection instead of USB. USB was never intended to be used for high quality audio, but it became fashionable and everybody tried to work around its limitations. I had promised myself to only start looking for another digital frontend when it would use a network connection.
After a long search I fell for a combination of a Grimm MU-1 streamer and a Mola Mola Tambaqui dac and realized my Harbeth 40.2 were not giving me all the goodies so I listened to quite a lot of loudspeakers, but none of them were so much better that the price was justified. To me, that is. Then I remembered PureAudioProject which I have been ‘following’ from the start. Although I did not have the opportunity listen to them I felt I needed to ‘get rid of the box’.
I contacted Ze’ev and he asked me what I was looking for. I wanted life size orchestra or band and it absolutely had to be tonally correct for strings, voices and piano. I also made clear I was not interested in another journey to fulfillment in other words an upgrade path. I have always preferred being in Rome over discovering all possible roads leading to it. Ze’ev offered to start with a Voxativ 1.6 and later upgrade if needed, but I ordered a pair of Quintet 15 with the Voxative AC-X field coil drivers, when I realized the difference in the way they are constructed compared to a standard driver and therefore their sonic potential.
After assembling and triple checking everything I switched the system on and then something remarkable happened. Literally within the first few seconds my love of my life HSP partner exclaimed: “These are going to stay!”. She was right of course. Gone were all the annoying distortions that you have learned to accept as being normal. The soundstage is wide open and accurate and stable. Instruments sound so believable. No edges, no grain. It is so clean. Voices are shockingly real. There is simply nothing annoying. In fact it was shocking and still is.
A very dear friend of mine is a highly regarded acoustics expert advising at recording sessions and specialized in optimizing recording studios and listening rooms. Last few years he is also a dealer for some carefully selected really high quality audio equipment. When he heard the set playing he really got emotional. After helping me perfecting the placement he cancelled his next appointment and stayed for over 4 hours instead of 1 hour as was the original plan. He still sends me messages about how amazing the set sounds.
We are still breaking the speakers in so apparently and according to Ze’ev there is more to come, but this is by far the best music reproduction I have heard. I do realize it is a lot of money. It is for me, but it is the best investment ever. I cannot say anything else. This is what I have been searching for all the time.
The fact that a person with HSP, who normally cannot stand loud voices or loud music is now asking for and enjoying for example live recordings of Pink Floyd or Dead Can Dance or a Bruckner symphony at realistic sound levels tells it all. It is truly amazing. Thank you Ze’ev!”
“I wanted to share my journey with other users, please help to share how great Quintets 10 is.
I have finally found a speaker that I can keep and enjoy the music.
Quintets 10 Horn 2 is the only speaker that has been staying with me for more than 6 months and it will be a keeper in my system.
Audiophile’s journey of finding the right speaker was very rough and long for me to find the right pair that I am not bothered by it but can enjoy the music. That is how significant PAP Quintets 10 is to me.
Just to make a list of speakers that I went through last 3 years.
Revel Studio 2, Magnepan 1.7i& 3.7i, Dynaudio Heritage special, Amphion 7LS, Buchardt 400 Signature, PMC DB1, ATC SCM 19&40, Lawrence audio Eagle, JBL S4700, Devore Gibbons 8, ESA Neo SE, SBacoustics ARA, ELAC UF5, ElAC BS 244.2, Dynaudio Xeo 6, GML Field Coil (full range).
Okay, I think you get my point. Other than the things listed that I have owned. I have listened to many more to date.
PAP Quintet10 is the most well-rounded, crazy deep 3D staging, details, voice, oh the trumpets, and the horns from this speaker. Speaker does an amazing job with the start, stop, and is very musical at the same time. I hope some of you guys will experience it.
Other than just being the best speakers, I love the fact that I can play with XO parts and wires so easily. It helps to understand more about speakers and what I need to do to make things better.
The only regret is; I didn’t take the chance earlier of going for PAP open baffle with the endless configuration possibilities.
If you are on a similar journey as I am going through, hope this sharing stops the chase and saves time by going with PAP. You will never get bored of it, always can change and update things, and will be new eye-opening.
Thx again for sharing the good tips on upgrade Ze’ev and always being helpful too.”
Customer, Tim, Singapore
“Hi Ze’ev, recently I moved to another house, bless to have a bigger listening room, 3.5x 5.8m, almost doubling in size. I am now able to place the speaker further away from the wall. This speakers is capable of performing at a higher level when given sufficient space to breath. It throws a room filling soundstage. Over the years, I have tried many box speakers of varying sizes in my listening room. None sounded right, especially the bass response, it’s always out of control and difficult to tame. Every speakers responded differently in the same room.
Prior to taking a plunge on PAP without having a chance to audition, I had a ——- on loan. I loved it’s full range driver, probably the most open sounding speaker I have come across. I still didn’t pull the trigger because for the lack of bass, bright recording can sound shouty and lead to aural fatigue after long hour of listening.
The Quintet 10 transformed my listening experience entirely, in a good way. I enjoy the beautiful and openness in the mid and high from the Vox PiFe driver, the woofers not only delivering satisfying clean and tight bass, but has also enhance the vocal range of the PiFe. Driver and woofers are beautifully integrated and complemented each other superbly. Soundstage is wide and deep and 3D. If I have use an analogy to describe the difference between the ——- speaker and Quintet 10. The ——- is a nice and flavourful piece of steak, the Quintet 10 has the appropriate amount of added marbling to the steak. The enhancement elevate the overall experience to another level.”

Trio15 Classic, Music and Video
” Profoundly unexpected…
Well, I have passed the half way point of my Trio-Classic break-in period and have started forming an opinion of the speakers. As one would expect with a speaker in this class it is remarkable. What has blown me away most is how astonishing the Classic’s are for movies! I am a tech-geek, I love my technology, hi-fi and big screen TVs. My speaker usage is 51% listening to music, 49% listening to action packed movies with great soundtracks. Until the Classic’s arrived I’ve always used a subwoofer and large B&W centre channel with +4db boost for dialog, otherwise the narrative gets lost in the sound effects (a compromise as the B&W is clinical, great for dialog but never matching whatever warmer speaker I paired it with).
For fun a week after the Classic’s arrived I turned off the subwoofer and centre channel, using ‘phantom’ centre mode instead (which has never worked for other speakers). OMG…crystal clear dialog that blended perfectly with everything on-screen…..and the beautiful bass that everyone prior has spoken about…heaven.
As a fair test, I waited another two weeks before running my favourite movie sub-woofer test…this time no subwoofer…only the Classic’s in play. Called my son in, turned up the volume, put on ‘Pirates of the Caribbean’ and we waited for the scene where ‘Elizabeth Swann’ falls into the ocean from the city wall. When submerged her gold medallion puts out a deep-bass-pulse effect. We sat in disbelief as that pulse travelled from the screen literally into our bodies. Profoundly unexpected.
Endnote: my son has now inherited my old speakers and subwoofer…I will post an impression of the Classic’s musicality after the break-in period has finished.
Enjoying your work Ze’ev & Thomas.”

Trio15 Classic (unique break-in)
Customer took a very unique approach to break-in the audio components and this is what he wrote:
“Innovative approach to sound. With Dirac room correction it sounds much better than it looks.
If people heard the sound, they would shake their head and wonder how that sound is possible. Definitely high end components!”
After few weeks all audio components were mounted in the Classic15 enclosure and this feedback came in:
“I was really enjoying the speakers until I brought out my Sugden a21se, which I was planning to sell. The combination of your speakers and that class A amp is beyond my dreams. Now it is a love fest. I am glad that I opted for the Voxativ PiFe. I would like to congratulate you on a very fine sounding speaker with a beautiful enclosure.”

Customer Review of Quintet15 that replaced his Jamo R-909
Just got back into vinyl after over twenty years away from it. Decided I needed the VPI prime scout with a Soundsmith Zephyr MIMC cartridge. My system now consists of: Pure Audio Project Quintet 10; PSAudio Stellar Phono Preamp; First Watt SIT-3 Amp; PSAudio DirectStream DAC; REL T/7i subwoofer; Pass Labs XP-12 preamp; PSAudio DirectStream Power Plant 12 regenerator. And yes, I think I am now ready to begin the 12 step detoxifying process, since I can now admit that I am an addict. The system sounds glorious, everything I could have hoped for. Ze’ev got me started on vinyl again with the Music Odyssey China LP – so I believe that I can hold him accountable for all this ., C.N., USA
“Ze’ev, when the duet’s first arrived, I have to admit, I was a little skeptical…
I was very pleasantly surprised with how tight and punchy they sounded and they have a very crisp and present top end without any harshness, in my opinion. Everything just sounds real to me. I wasn’t expecting that at all. In fact I already sold my Graham ls 5/9’s, which are great speakers in my opinion. I was really just trying the duets’s out of curiosity but I fell in love with their sound and had to have them. Thanks Ze’ev, love them.”
S.B., Customer, USA
“Hello Ze’ev, great to hear from you…I’m not sure how many hours I have on them but probably at least 50 hours and I love them so far. They’ve quickly become one of my favourite speakers both from a sonic and aesthetic perspective. Thanks for checking in. My next plan is to get a tube amp as I think it would be a nice match.”
Few weeks after:
“Like many speaker and audio enthusiasts, I started my journey with box designs, and, while there were several models and brands that offered excellent sonic performance, I had the urge to venture out of that traditional speaker realm and try something unique. Planar and electrostatic speakers provided a clear and airy sound and were attractive but the trade off was that they often lacked bass impact and dynamic range and were difficult to integrate with a subwoofer. It was only until the last couple of years that I became interested in open baffle designs. They seemed to offer the best aspects of both box and planar/electrostatic speakers, and typically do not require special room treatments. The difficulty, however, was finding a reputable company that offered affordable, high quality, and complete, open baffle speaker models. I had neither the time nor skills to go the DIY route. Hearing about PureAudioProject was sort of a revelation. I spent some time researching and reading about their speakers before reaching out to Ze’ev, who was was extremely helpful and responsive and addressed all of my questions. I am now a proud owner of the Duet15 Prelude (Tang Band version). I actually have the privilege and honor of being one of the first customers of this new model. Setting them up was extremely easy, even for a novice like me, and, even during the first few days of listening, I was astonished at the effortless and balanced sound. There is a musicality and naturalness to these speakers, handling any kind of musical genre without any struggle. And there is no lack of muscle and punch for those who want to rock – indeed, you will be surprised at the quantity and quality of the bass. It is a textured, controlled, and precise bass. You will not hear any boom or wooliness here. And the woofer is perfectly integrated with the full range Tang Band driver. There is no dip in the mid-range to create the illusion of more bass, and no sharpness or brightness in the treble to artificially heighten detail in the music. Apart from the exceptional sound, these speakers are just beautiful and will blend seamlessly into listening rooms with its modern, elegant look. The baffle construction and finish is also top notch. You can tell they were crafted with care. I’ve already received a few compliments from family members who usually have no interest in speakers. Finally, a special mention to the excellent customer service at PureAudioProject. Ze’ev and his team are a class act. I very much look forward to trying their higher end models in the future. For now, I will enjoy the wonderful Duet15 Prelude for many months to come.”

I am a longtime horn speaker user. Over a 17-year period I have combined various horns with high efficiency 15” woofers for ported bass. For a long time, I had been thinking about mating open baffles to horns. I wanted to get the directional acoustic benefits of dipole lower midrange and bass in my large but somewhat difficult room. I craved a fully boxless sound like I have heard in open baffle systems at shows and high end stores. At the same time I wanted to stick with the dynamic and r ich sound of 15” woofers.
I wasn’t sure exactly how to proceed with my plan – until last fall when I read a review of the Pure Audio Project Quintet15 speakers. I immediately realized they were the solution I was seeking. I was also intrigued with the mix and match modularity aspect. I read everything I could find online about PAP speakers. I contacted Ze’ev and soon the boxes with modular components started rolling
I feel like I hit the jackpot. Out of the six horn systems I have owned, the Quintet15 Horn1 speakers are the best: accurate tone, highly resolving yet smooth, great imaging, dynamic. With the brilliant Leonidas crossover the Horn1 compression driver blends really well with the open baffle woofers. Bass is so realistic and nuanced and enveloping… Charles Mingus lives!
I love the possibilities of the modular design. I have the option of swapping out the horn and trying a wide range or ribbon driver. If I move or my wife redecorates, I can easily change the baffles to match. Speaking of the wife, she really likes the look of the speakers. But the curvilinear frame isn’t just for looks since it physically time aligns all the drivers to the ears at the listening position.
After trying a variety of amplifiers, I decided to use a Pass Labs XA25 with the Quintet15s. It’s a terrific match, a sexy little dominatrix that can show those eight woofers who is boss. Meaning: the speakers are quite efficient and don’t need a lot of watts, but they do like firm control via high amplifier damping, and the compression drivers like the sweet but very detailed Pass Class A sound.
For icing on the cake, I use Juice HiFi Audiolense software to provide flat psychoacoustic frequency response at the listening position in my challenging room with lots of windows. The software works extremely well with the PAP speakers and the Leonidas 1st order crossover.

Trio15 Voxativ PiFe
Well these woofers babies are broken in now. Good grief that was tough going for many hours but now these speakers make beautiful music. I listen to a lot of different types of music and I think these speakers handle just about everything I listen to the very very well. Certainly acoustic music is where these really shine. In fact I haven’t heard anything quite like this before. In addition to acoustic music such as 50s-60s jazz…. One of my favorite types of music is progressive rock ‘n’ roll. I don’t know if you know bands like King Crimson and Porcupine Tree or (early) Genesis but the speakers know how to do that very very well. These bettered speakers I have had in here that were a lot more $$ $… with ease.
To get these broken in I had to put some blankets over the speakers and play and a fairly loud rate while I was at work to finally get through the break in. But it was well worth the effort. I am scared to see my next power bill though as I have A class amps that are costly to operate. The woofers have 230 hours and sound great. The Voxativ FR drivers only have 30 hours and sound amazing! I am not hearing any changes with the Voxativ after 20 or so hours.
yes I’m having fun.

Trio15 Voxativ (with AC-PiFe driver) with Thomas Mayer (VinylSavor) amps and phono stage, USA
Here is a picture of the Trio’s in my 17x12x8 foot room. All my equipment is from Thomas Mayer, line stage, D3a phono and the 300b’s. The TT (which will be changed soon to a Garrard 310) is a Technics SP10 Mk2 with a Kuzma 14” tonearm and Airtight PC-1 Supreme cartridge.
The Trio’s work wonderfully with Thomas’ equipment. In fact, the Trio’s are so efficient I may need to reduce the phono stage gain to give myself more headroom in terms of controlling volume.
I find the Trio’s produce a very wide and deep soundstage and a beautifully balanced tonal range, which is one parameter I am most concerned with. I get very refined bass down to 32hz and superb dynamics. I just find instruments sound much more like live performance.
Although the quintets are interesting, I doubt they would work well in a room this small so it’s the trios as long as I am in this space and I don’t see any deficiencies.
I will be changing the caps soon and I know they and the drivers take a while to settle in, so I look forward even more refined sound.

I finally had enough hours on the speakers to begin set up. Removed all but two base traps and all wall damping. Added plants for diffusion and played with positioning. Partially tamed a bass node, otherwise everything is just awesome. They make excellent bass in my room, pretty much exactly as advertised.
I cannot believe just how terrific they sound. They do need some care in height, slope and position in the room to get the best from them.

Last night made a sidestep. A friend of mine was so intrigued by my project that he has only just ordered from pure audio project. After a few weeks, all necessary parts within the Tang Bands after. And I let it all be told now. 🙂
Exciting, you can not hesitate to call him a spoiled listener. Many speakers have been reviewed and thereby was no more or less looked at a eurootje. B & W 804 D, MartinLogan the Summit, Focal Electra, Sonus Faber Homage, Chario Ursa Major are just a few speakers who have stood in his living room. But he could never find it in one way or another.
After initially equally nice to have visited a restaurant, you could put it together from the start Trio15 TOs. Almost everything is put together by hand.
And a half hours later, this was the result
Good music! Within seconds both our mouths fell open in surprise. What a soundstage. And with what ease. The rod band is of course already anticipated, but the EA’s are fresh out of the box. Also I have heard many speakers over the years, ranging from ? 500 to ? 50,000, but these speakers are in a league of their Own. ”
We enjoyed until very late at night. No single piece of music was too much for the Trio15 and it was never tiring. “I believe that I have never had such beautiful and musical speakers” was briefly the conclusion of Kees. And if you then consider that these speakers are in the living room for under 4,000, you can only conclude that this is a tremendous value for money.
I’m glad I decided to build it after. Am very curious how they sound when they are managed actively, but if I can believe the reviews then it will only get better. On to the garage …
Trio10 Beyma (bi-amped with miniDSP)
Hi Ze’ev , hope you had a good time at the Munich show. Any way my speakers are just beginning to open up and the sound is already awesome. I can’t imagine how good these will be after the mandatory 200 hrs of running in!
Mohd A., Malaysia (feedback on Facebook)
Few weeks after:
I must say after about 200 hrs the speakers gives me endless hours of listening pleasure.what is important to me is I am able to listen to music without the the distraction of the components in the audio chain. This is achieved after Timeless opened up. The sound is fuller, robust yet without loosing nuances. The highs especially are 3d . I have listened many high end speakers but the highs of Beyma are something else !

Trio15TB with Piano Black Baffles
Hi Ze’ev! Everything went smooth, had little problem with vibration around 50 Hz at reference listening levels , but after tightening all the screws problem gone. I bi-amp actively, using two tube monoblock amps for mid and high, two solid state amps for low end, and minidsp active crossover. I’m pleased with results a lot, compare to my DIY OB speakers, Trio 15 TB has more balanced, more spacious sound and less vibration. Bass extension really good for open baffle design, however I use it with two subwoofers, and love the sound even better. Also I love the look of piano black baffles, they fit my interior very well.
Trio15 Alu Frame
Ze ‘ev Hello my friend,
The new frames are beautiful and quite ridged. I thought the speakers sounder great using my old stands, but the lack of coloration with the new stands is startling they sound so much fuller and open. There is something whole about the sound, as if the speaker speaks with one voice….very immediate and so good at expressing the subtle nuances in each recording, I am quite impressed. So assembly was easy put all the bolts in and assemble everything before tightening worked best. One suggestion for the crossover mounting I placed a rubber grommet (your red washers) on either side of the board at each mounting screw tightened them to just being snug, seems to help dampen and isolate the board. Also a few nylon wire clamps to hold all the wires in place would be nice finishing touch. I can not wait for the new drivers…….Very well done my friend these are an incredible bargain. I had several musician friends over last weekend and they were quite impressed, although they were a bit pinched by the price they were thinking that they could live with just the full range driver and gradually add the 15″ drivers. I am currently using a pair of S3 REL subs to make these truly full range and the sound is thee best I have ever had in a system!
Harry Ferguson III
Few weeks later (after receiving the A15neo drivers):
Well after many hours the drivers and cables have broken in, midway through a Bob Dylan Album
the whole sound just suddenly relaxed. I have been using a Musical Fidelity KW500 integrated amp, the sound is
quite good, the imaging is beyond anything I have experienced, decay and attack are as good as live music. Voices are incredibly delineated. Last night I listened to original Elvis recording and the age of the recording is incredibly recreated from the tonality of the vintage microphones to the hollow sound of the recording venue…astonishing! So I know wish to pursue bi-amping the speakers and was wondering is it at all possible to obtain a unpopulated pair of the circuit boards used for the crossover with the binding post, so I can drive the full range driver with a tube amp. Are they available and at what cost?
BTW I am using Morrow wire for the Speaker harness and the runs to the amp SP-4

I never ever played Thunderstruck AC/DC so loud, and then it even can go louder, every thing you hear you can feel as well. Every instrument or voice that’s added gets it’s one place in the stage, I’ve tried several times to stay in my chair, but I can’t, must play my airguitar like a mad men, it gets me high……..this as near to concert like preformance as I’ve never seen.
Listened to music that’s been able to move me before, now it can make me cry, not because of ‘how perfect or analytic it is but because the music let’s me in and tells me its all right, that this is the way it is supposed to sound. It just comes so naturally, easy, no effort at all.
I’m wondering what this will do with a nice tube pre-amp or amplifier but short of cash for now
He Ze’ev, since I have been retired I have been building these Horn-OB Speakers . And of course they sound a lot better for me than these Proac carbon 8 spekers .
Rachel, The thumb nuts and bolts along with the speaker cables arrived safe on Friday afternoon and now everything is finished. They sound great, thank you for your help. I’ve attached some pictures.

“… So far so good. At the moment, a bit too much bass, a good problem to have with an open baffle. Huge variation by moving the speakers a few inches. When I have time, will check the room response to ensure I have smooth bass response. The FirstWatt B1 crossover has 20Hz 6dB gain. Current settings recommended in B1 manual for similar config. Low pass 80Hz 12dB/octave. High pass 160Hz 12dB/octave
BTW. The first friend I had over to help me setup likes them and may order a set through Rachel.”

Кстати щиты отлично (на мой неискушенный вкус) играют электронную музыку типа и проч. Возможно, даже несколько лучше, чем музыку с натуральными инструментами. То есть несмотря на отсутствие важных для электронщины баса и суббаса, звучит отлично, не по клубному конечно, но живенько, объемно, динамично, не скучно. Звук для взрослых :)))) которые не любят клубы, но любят электронщину.
Few things! First thing that really surprised me was the bass, i did not expect that, the other thing is the clarity in the sound and they are barely even breaked-in yet and I’m running it off a shitty amplifier that is already doing pre-amplifion…
The other thing is that it fills the entire room, that is truly amazing!
I need to wire up my class-D amplifier and test it with that instead..

Just wanted to send (another) blurb on The Timeless.
After 300 plus hours playing a variety of music it has gone through another transformation. The Timeless plays music with an uncanny sense of realism. It never seizes to amaze me. I’ve always appreciated open baffle bass, but I have never heard this kind or amount of bass from an open baffle speaker before: The bass is open, relaxed, and impactful. (The Timeless should have no trouble turning doubters into believers).
As for the rest of the frequency range it is smooth from top to bottom. Playing from my “battery-powered” system, the background is dead quiet… which just leaves me and my music…

…Bisherige Höreindrücke: bei geringer Lautstärke ein sehr voller Klang, Bass, Mitten- und Hochton sehr ausgewogen. Bei zunehmender Lautstärke gewinnt der Bass an Präsenz, während der Mitten- und Hochtonbereich leicht in den Hintergrund tritt. Dadurch ist das gesamte Klangbild auch bei hohen Lautstärken angenehm, kein überzeichnen oder gar schrille Töne.
Es macht einfach Spaß, mit den OB Musik zu hören. Es wird nicht langweilig, es klingt leicht & luftig, unangestrengt ist das beste Wort dafür.
Wir haben in den letzten Wochen sehr viel gehört und bei bekannten Musikstücken teilweise Feinheiten gehört, die wir vorher nicht kannten.
Beispiel: Das Stück “Time After Time” von Cindy Lauper, über 30 Jahre alt, hat uns beim Refrain überrascht. Der Bass hat nicht nur verschiedene Tonhöhen sondern auch eine Melodie, die wir so bislang nicht kannten oder gehört haben.
Um diese OB optimal Stellen zu können, benötigt man allerdings einen großen Raum, m.E. Mindestens 25qm aufwärts. Die Wandentfernung nach hinten sollte schon 1 Meter betragen, die Systeme dürfen gern auch weiter auseinander stehen, die Bühne wird dann noch größer. Wir haben die Wohnzimmertür ausgehängt und eine Schiebetür eingebaut, damit wir den vollen Raum nutzen können.
Kurz: wer sich etwas traut und kein Markenfreak ist findet hier für kleines Geld sehr viel Klang und Spaß.
Elektronik: McIntosh C220 & MC252 & MC301, Wadia 170i Transport für IPod, Silent Wire NF & LS 32
Mit dieser Vor- Endstufenkombi spielt dieser OB präzise und schnell. Auch sehr hohe Pegel sind sehr gut hörbar. 🙂
Ich hoffe, die ausführliche Rezession ist hilfreich für Dich.
… All the components have reached super fast and in great shape.
My daughters and wife encourage and support all my experiments and are eagerly waiting for the build to get done which I would complete by Tuesday night.
What cut off frequency would you recommend for the TB and eminence combo? … ”
answer: “…Hope all will go easy and smooth and that you’ll have fun ! I would prefer to share than recommend on the cut off frequencies 🙂 since it is hard for me to make my mind between the following three points: ~180Hz, ~250Hz and ~450Hz… I guess my favorite is the 250 but the passive XO that BluePlanetAcoustic designed is close to 500 and sounds amazing. The cutoff freq IMO has noticeable impact on the mids, While the TB is sweet, accurate and refined, the Alphas have larger body and presence… and… the amplification also contributes to what will sound a better match… I would start with 250 and move left or right.
Also, if I recall you use a DSP… I do add 3 to 6 DB from 100HZ and down in a linear slope all the way towards 40hz and sometimes boost the highs in 2 to 4db from 10k (do it when need to impress)… all are matter of taste as there is no accurate and common base line to our ears and souls 🙂 flat is a good starting point but our senses and responses differ and are definitely not flat…
Hope this was not too much mind boggling…”, Ze’ev
after a while:
… Ze’ev, I finished the build and tested the speakers with the DSP and bi amps. At 250 Hz cut off its FANTASTIC. This is the first time I have hear Open Baffles, the Bass is crisp, live and vibrant. I was also awed by the TB full range drivers, they are electrifying to say the least. Above all the sound is completely uncoloured and that is what strikes instantly.
I am now awaiting a mic to be able to test the speakers and adjust the filters, I shall try out 350 and 500 hz cut offs. I and my family have taken a picture which I or madhvi(my better half) shall forward.
I am off to —– for a few days, can’t wait till I get back to complete the experimenting and tuning.
I am sure there are at least 3 friends/family who will want me to build for them. Shall keep you posted!!

Yesterday evening two friends came to hear the Timeless at home. One is from optimizeaudio.com. They are doing a lot of “hifi-dgets” and are a bit guru-like.
Nevertheless we have tried an anaview based amplifier (1200-2600 if my memories are ok). Way more rapid than my emotiva, nice surprise…And a power conditioner + out of space cables. To be honest, I’m a believer but not practicing the high-end cabling/filtering religion…
Well Ze’ev, the Timeless scored full marks! 4/4 friends found the Timeless to be a hit!
They have B&W802D, Magnepan 1.7, Focal Utopia, ATC, etc…and qualify the Timeless as great loudspeakers. I guess some of them were antagonized when the tought about the performance/price ratio…
Last listener I expect/respect is my friend Richard, he is recording all kind of classical music in Switzerland and is a musician himself. He is the most critical listener I know. I’ll let you know for this last listening session I have on my list…
…the project turned out super awesome, and the sound even better! I have taken some photos of the speakers i can share, and I’m planning on Building a matching tv/stereo furniture before posting on your website for a nicer stereo setup look.
I have to tell you about the first time they gave me that lump in throat feeling, right after they had loosened up a little i sat back and listened to Phil Collins’ – in the air tonight, and when the drums kicks in at the end it was like getting the whole drum-set thrown in my face!!! It was awesome I hope you guys will have great success with your projects, they deserve it…
