Music experience with the Duet15 Open Baffle Speakers is open and big even in small rooms. It is a full scale open baffle speaker that bears no compromises on tonality and music presentation. Despite its relatively modest size, the Duet15’s life-like and extremely musical performances stunned customers, reviewers, and industry members alike. One of our most popular models.


For realistic, full scale Open Baffle music experience in smaller rooms


For effortless and dynamic sonic performances with any amplification


For reliable music reproduction and overall seamless sonic blend

“The Duet15 Open Baffle Speakers are anything but entry-level. They could certainly be an end-game for many. They are dynamic, with a lightning fast attack. Strikingly lifelike at times. I listened to almost every genre of music, the Duet15 sounded sterling with them all.”

Gary Beard, Positive Feedback


Full Range Drivers

Full range drivers are known for their rich, organic and musically engaging presentation. Being built with one motor (magnet system) and one membrane, there is no shift in phase nor in sonic signature all the way from the low mids to the very highs. This causes sonic signature stability and eliminates the need to cross two drivers with two different sonic signatures (mid and tweeter) in a critical listening frequency zone.

Voxativ AC-1.6 

Japanese Paper Cone

Over the years Voxativ full range drivers won their position as the ‘gold standard’ among full range drivers. The Ferrite magnet / Light Japanese paper cone AC-1.6 driver is a ‘classic’ and this is the driver that was featured in the Audiophiliac (Steve Guttenberg) reviewed model. Its built quality is top-notch and sound is realistic, smooth, full-body, transparent, with all the clarity, resolution and a beautiful sonic finesse. This driver is a natural match with the Duet15 design and highly raved by Duet15 owners.

Voxativ AC-PiFe

Wood Cone Ferrite Driver.

This unique driver adds to all the features of AC-1.6 an unprecedented sense of sonic-mass and realism. Instruments and vocals not only ‘sound great’ but also are ‘physically felt’. The music experience with AC-PiFe in Trio15 is simply addicting!


With years of experience and customers in different climate environments, we have narrowed our baffle materials to three types that excel to perform even in high vibrations scenarios, 3/4” High Density Fiberboards (or Plywood), 3/4” three layers Bamboo or Wood sheets, 7/8” genuine German Oak (with anti-vibration inserts).

Their unique finishing will compliment their music performances, and both will blend naturally with the life-style of your room, your office, or your cave

HDF/Plywood baffles are finished to matte or gloss, while Bamboo and wood baffles are cut to maintain the grain along the speakers and are oiled.
In addition, for desired custom finishes, please contact us for an offer and a quote.


German Oak

Our genuine German Oak baffles are cut from long pieces of wood and numbered to maintain wood original grain.

They are handcrafted with a unique 3/7″ (1cm) deep insertion for extended strength and anti-vibration; smoked and oiled to the selected finishing;… all per order by Holzbodenmanufaktur in south Germany.





OB-A15SEN aka NEO are our proprietary audiophile grade, high-resolution 15″ woofers. They were designed specifically  for Open Baffle and for PureAudioProject in co-operation with Eminence. The OB-A15SEN are extremely light and fast response drivers that are not only field proven and great performers of deep bass, but they also play full body midrange and integrate smoothly with fast and refined drivers that are used in the different Trio15 models.  

“Well well… the deep bass coming out of these speakers, it’s not just that is a deep and ‘feeling it in your chest’ thing; yeah, I felt that before, but the speed of these woofers is just in another class from everything else, it just is. Yeah, I’ve never heard anything quite like that in this room”

Steve Guttenberg, The Audiophiliac

Watch the hi-fi journalist Steve Guttenberg (The Audiophiliac) explaining: Why I’m Changing my Reference Speakers to the Duet15

This is the review that Steve posted prior to his decision to use the Duet15 as his reference.


“The most amazing part is that the music just seems to flow effortlessly through them… So probably for the first time in many years i am actually enjoying the music rather than trying to analyzing my system!!”

“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”

“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.”

Customer, Duet15 Prelude w/ TB W8-1808

“Really enjoying the speakers. They are truly the best sounding speakers I’ve ever had. The resistors on the inputs to the Voxativs worked well. The treble is crystal clear and extended, but without a bit of glare or harshness – unlike my last speakers, XXXX from Finland…”

Few weeks after: “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.”
