Duet15 Prelude

“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.”

“The speakers sound amazing, they fill the room with amazing clarity and make me think theres a concert in my living room.” ~~A.D.C, Dominican Republic

Duet15 Prelude

Zeev, you have a winner. The Duet15 is working very well in my room. I was stunned with the details, vivid-pinpoint imaging, as well as the fast and tight bass. I am letting it to run in at pretty loud volume right now. It has great potential!

Duet15 Prelude

High level summary:

1) The Duet speakers are incredibly precise in rendering recordings, without being nervy or overly high pitched.

2) As highly efficient speakers they run well on any equipment and are more balanced on low volumes.  These speakers also raise the bar for low cost equipment.

3) The bass is very impressive and never rumbling.

4) Overall they are very musical and work well for classical music.  As many have noted their spatial reproduction is as good as is central focus on those voices or instruments that are actually located there. You will learn a lot about how your recording was engineered.  Stereo CDs will have a come back, you will hear them like never before.  I do not play vinyl and never looked back.

5) Their overall tone is warm and very balanced, I leave all my tonal dials on neutral and it sounds best.

6) I was shocked when comparing them to my existing speakers, it was not even close.

7) These work for pop and rock as well as for classical music.  Singers voices come forward as I never heard before. 

8) Assembly was easy and uncomplicated.  Questions were promptly answered by Ze’ev or Cynthia.

 

These speakers were the most expensive I ever bought.  But I always owned well manufactured speakers, if more on the budget or mail order level.  These were the first that I compared carefully with my existing ones. I also went to listen to Klipsch Scala speakers to test whether the investment in high end speakers is worth it.  I read and listened to many reports about the latest speakers to filter out quality from marketing.  Steve Guttenberg is my man.

 

My equipment is simple: Yamaha A-1060 CD/SACD player or macbook with a $100 Schiit DAC to Yamaha R-S500 stereo amp.  I play a lot of CDs, DVD-A or SACD records and now a lot of Qobuz high-res streamed files.  I love old re-mastered recordings that were recored in the 60s and 70s. They were often very well engineered and I have heard them a million times.  Most of them sound as good as anything today.  I also like multi-track surround sound recordings for their immersive quality.  The Duet speakers are the first that I own that create this special surround feeling again, even from stereo sources.

 

These speakers are for people who like to listen to music, really any kind of music.  Once you get used to them the technology should disappear and the artistic intent of the record should speak for itself.  To me that is what these speakers will do for most listeners.  One benefit of the Duets over the larger versions, which I have not listened to so far, is that they don’t require a change to the room design, even though they are larger than any speaker I have owned by being wider than usual and quite tall. 

 

A 15″ sub woofer makes a huge difference even for classical sources because it sounds more relaxed at lower pitches.  Additional subwoofers are not needed to create a fuller impression or a stronger rock’n roll power.  The Voxative drivers convince in transporting voices and entire orchestras clearly and fully.  It is amazing that this full sound is produced by essentially a flat board without a box.  The Duets look deceivingly simple and produce a counter intuitive range of sound.  You just don’t expect such a warm rendering from an open baffle speaker.  Breaking them in (I played Christmas elevator music for 8 days on them in a closed room) is not just recommended but required, the sound after 200 hours of low level play is as expected: clean and clear. 

 

One of the most appealing qualities to me is that orchestras, solo instruments, organs and voices have a natural sound, effortless and unaltered. The speakers are made for acoustical recordings.  But I can also make out acoustical qualities of the spaces and microphones like I have never experienced before.  The sound is transparent, without overemphasizing high frequencies or tweeters.  Even old CDs suddenly have a bass quality because the speaker and amp don’t have to lift the lower frequencies.

 

Who would I recommend these speakers to?  This is a hard question because we all have such different tastes,  and many reviews of equipment is overly technical.  I am sure there are other speakers that satisfy your taste.  I would say that these speakers create an incredibly comfortable sound and invite you to try your old sources.  They will also show you qualities you have not heard before.  And I haven’t regretted spending some extra money because when I sit and listen carefully they transport sound I haven’t experienced in my home before.  What can be more rewarding.

“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 a detailed review came in by mail:

“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 ele ctrostatic 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.”

“Ze’ev,

“Here they are and sounding great. I had Magnepans years ago, and these compare to them in having a “big” sound, only with punch. Your larger speakers must be incredible.” 

Few days later: “ Really enjoying the speakers.  Really smooth.  I was used to an aggressive treble (titanium tweeters) on my old speakers, and these are way different, and one of the reasons why I wanted to move on from the old ones.

  Thanks, Ze’ev”
