DUET15 Prelude
All the sonic bliss of large scale Open Baffle Speakers for small to medium size rooms

“Really enjoying the speakers. They are truly the best sounding speakers I’ve ever had… I had Magnepans years ago, and these compare to them in having a “big” sound, only with punch…”
R.B., Customer, USA
Watch Steve Guttenberg, ‘The Audiophiliac”, explaining on YouTube:
“Why I’m changing my REFERENCE speakers to the Duet15”
“the speakers that put me thru some serious changes… recordings are just coming alive in my room… It sounds like the music is just set free… I think I am in love…”
“Although Ze’ev Schlik says the Duet 15 Prelude could be a stepping stone, its performance in the Tune Saloon clearly demonstrated the Voxativ equipped Duet is anything but entry-level. It could certainly be an end-game for many. I’ll say this without hesitation: The Duet 15 Prelude is a first-rate loudspeaker that tickled every single personal sonic-fancy.”
“For all its outward simplicity, the Duet 15 Prelude’s sonic quality is quite complex. It is dynamic, with a lightning fast attack. Resolution of fine detail is excellent, and tonal color is strikingly lifelike at times. The Duet also gets high marks for an amazing ability to construct a believable image, and set those images into a wide stage.”
“During my time with the Duet, I listened to almost every genre of music. And while some speakers are more capable with one type of music or another, the Duet sounded sterling with them all.”

Reviews and Customers Feedback

“As I remarked earlier, I’m very pleased with the quality of RJ workmanship; the baffles were well done and are beautiful. To date, the system already has over 100 hours of play and should definitely have 200 hours by the end of next week since the system functions at least 15 to 20 hours/day.”

“I’m very satisfied with my purchase. In an earlier email, upon first hearing the speakers, I liked them immediately. And now that the speakers have 300 hours of play, the sound is top grade.”

“The speakers sound amazing, they fill the room with amazing clarity and make me think theres a concert in my living room.”
Customer, Duet15 Prelude w/ Voxativ AC-1.6

”After a month of playing I think the Duets got stable and they are burned in completely. The sound is amazingly good. It is all there, the focus, the stereo image, the powerful but detailed bass and the incredible Voxativ mids and highs. You never get tired listening. I have a broad spectrum of genres I listen to. No matter what, the old Mingus mono records or the latest HD classical recordings, the jazzrock 70’s vinyl., they all sound as I never heard before.”
”Listening now to vinyl, the Village Vanguard Session of Bill Evans. The Duets reveal even beautifully the slamming of the strings against the fingerboard of Scott LaFaro’s bass. Never heard that before. So lots to discover today”
Customer, Duet15 Voxativ AC-1.6

“I’ve been having absolutely amazing experience with the upgraded drivers to Voxativ on these PureAudioProject Duet15. The sound and soundstage improved and it was already really good with the Tang Band drivers. Running on under a watt and still impressive from adjacent rooms.”
”Just amazing that these drivers have a Wilson-like delicacy and ability to play soft parts of music softly and louder parts loudly.”

“Hi, I am a new owner of Duet 15 Prelude with TB W8-1808. I am blown away by the speakers and love them…”
Customer, Duet15 Prelude w/ TB W8-1808

“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.”

“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.”
Customer, Duet15 Prelude w/ Voxativ AC-1.6

“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 later:
“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.”
