The 7′ high Quintet15 offers a true ‘wall of sound’ music experience, with unprecedented presence, realism and clarity. With eight 15″ woofers, designed to play from the low end deep into the mid range, the air moving capacity of the Quintet15 is simply striking. Vocals and instruments, at any scale, feel full body and as close to real-life as it can get. All sounds effortless to a level that speakers truly disappear.

“Reviewers often opine about whether a particular speaker could be appreciated (that is, used/owned) long term, or even forever. The Quintet15 is that sort of speaker”

Douglas Schroeder, DAGOGO

“I got the speakers set up and was blown away by the new “depth of field” and the wall of sound! 8 x15″ drivers is really something! Listening to: Progressive rock, King Crimson, Porcupine Tree, Tool (latest album is amazing), Margerit Argerich – Liszt, Beethoven Piano Concerto 3 in C minor – Gould, Bach Goldberg Variations, Bach English Suites, lots of 50-60’s jazz.”
J.S., Quintet15 Owner, USA

״the Quintet15 takes its place among a cherished handful of great examples of speakers that are true music instruments.”

Jeremy Kipnis, EnjoyThe Music


For realistic and no-fatigue music experience


For effortless and dynamic sonic performances with any amplification


For reliable music reproduction and overall seamless sonic blend

The Quintet15 speakers feature four of our 15” open baffle woofers and a selected center driver in a D’Appolito design. Center drivers and crossover components are interchangeable and the choice is yours. 

Once decided on Quintet15, the next step is to choose the center driver and baffle finishing.


Though the overall music experience with the different center drivers is quite similar, every driver highlights specific sonic features reflected by it’s build and technology.

Read about our center drivers and choose the one that matches at best your music and sonic DNA, your room acoustics and your favorite audio gear.


Co-axial 10” mid-range w/horn tweeter

Our newly released custom Coax10 center driver, was designed to push the sonic envelope to the edge, but without loosing the organic and emotionally moving presentation, warmth and musicality.

The Coax10 driver features a high-end 10′′ mid-woofer with a light-paper cone and a 1/4′′ Horn tweeter with Polymer dome (similar to our Horn1), but differently from typical configurations, both are mounted on the same axis, aka Coaxial design.

Such an advanced coaxial center driver, with  mid and tweeter in the center and woofers in D’Appolito design form kind of a large-size point-source configuration that makes all sound organic, natural and no fatigue with the finest details and nuances while speakers disappear.


“The resolution and nuance retrieval capabilities of the 10” Coaxial driver are pleasantly beyond what I had expected! The larger mid-bass driver and the tweeter are able to send through to the listener as much information from the signal as I hear from the electrostatic, omni, or line source designs I have used.

…The Coaxial driver is so generous that it reveals the quickness in the fingering of the strings, and is plush enough to capture a wide range of detail, from the initial scraping and release of the string to the peak of its vibration. For the better part of twenty years, I have worked to get systems to present the bass line clearly. It is not easy to get an audio system to reveal the bass line distinctly.

…The Trio15 Coax10 is masterful in moderating shrillness, whether instrumental or vocal. In your system, relative to the other PureAudioProject center drivers, the Coax10 will be warmer sounding and riper sounding.


Douglas Schroeder, Dagogo


Wide-range 1.4” Wooden Horn

With Horn1in both models, the Trio15 and Quintet15, the border line between live performance and reproduced music simply disappears. Instruments become live… live in front of you… fast, dynamic and full body.

With it’s unique soft Polymer dome, large throat, strong Neodymium motor and wide wood waveguide, Horn1 presents a warm and smooth sound, with all the dynamics, fast-responce, clarity and resolution great horns are known for, but without any typical ‘horn-harshness’ whatsoever !

With your eyes closed, this will be impossible to point on the drivers. D’apollito configuration sets the sonic-center-of-mass exactly at the horn throat, and this turns the Trio15 into kind of large point-source disappearing speaker.

If you are a fan of horns and/or want to experience the magic of horn-based speakers, you should seriously consider this highly acclaimed and award-winning model, the Trio15 Horn1.

“Great as these speakers sounded at Hickman’s house, I was still expecting that pinched horn sound. None is present in the Trios – zero.

Hours pass by and on many occasions, what begins as an afternoon listening session, lingers far into the night hours – even with daylight saving time in full effect. A wide range of music proves highly engaging and exposes no flaws in the Trios. They play everything you can imagine with ease.

Enjoyable as these speakers are, you need to hear them. Their clear, dynamic sound reminds me of so many aspects of other speakers that I truly love. They disappear in the room and provide pinpoint imaging when required like a great mini monitor, yet, they paint a vast, diffuse landscape like my Magnepan Tympanis, all the while, having the sheer sonic punch of the Klipsch LaScalas.

Jeff Dorgey, ToneAudio Magazine


If you are a fan of Full Range Drivers and/or looking for music experience that is just life like balanced, effortless, spacious… you should look at Trio15 with one of the Voxativ 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. Also, there is no need to cross two drivers with different sonic signatures in a critical listening frequency zone.

Many describe the sonic experience of Trio15 with Voxativ drivers as ‘organic’ and ‘realistic’. Indeed, their build, their blend with our light and fast15″ woofers, the short  audio path crossover (1st order, series), and the D’appoiito (WMW) configuration, all make music sound and feel as if ‘musicians are in the room’; which is in many cases how our customers describe the Trio15… (read Customers Feedback and Revues below).

Over the years Voxativ full range drivers won their position as the ‘gold standard’ among full range drivers, and we have selected three specific models that work at best in our designs.

All three sound extremely natural, rich and smooth, with all the clarity, resolution, and beautiful sonic finesse. No typical mid ‘stoutness’ whatsoever that many full range drivers suffer from. They differ in their build and this is reflected in each one’s unique sonic features.

Voxativ AC-1.6

a classic full-range driver, with Ferrite motor and light Japanese paper cone.

The AC-1.6 built quality is simply top-notch and it offers a truly emotionally moving music experience. Smooth and full-body, transparent and airy, with all the resolution and clarity, this driver is a ‘classic’ and a ‘no-hesitation’ choice for Trio15.

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!

Voxativ AC-X

The Field Coil

This driver is a league of its own and its musicality and sonic performances are on a level that is rare with conventional drivers. The dynamics between the instruments and their definition in time and space are no less than striking. All sounds extremely organic and smooth, with resolution to the finest details coming from the depth of the driver in a totally effortless way.

AC-X design and build, as well as the AC-1.6 and the PiFe are a blend of engeneering, art, and deep understanding of drivers technology and acoustics…


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


All our speakers are shipped with passive crossovers that feature audiophile grade components values and types carefully selected for the specific model. Except for the Trio15 Coax10, that comes with a dedicated crossover, all out Trio15 speakers work with our first-order series short-path crossover. All components on Thrier crossovers are mounted with a screwdriver at Gold screw terminals. This allows you to swap and evaluate various brands and types and even values of components, to enjoy the process, and if needed to fine tune your speakers to your personal sonic preference, your room and your favorite audio gear.

Differently from the Thrier, the crossover for Quintet15 Coax is fourth order for sharp slope integration between the mid and the tweeter drivers and a second order Low Pass Filter for the woofers. The types of the components on this crossovers were sonically matched for their specific task and no compromises were taken with regards to their grade and cost. Silver/Gold Oil, Foil Coils are High Res Foil Resistors are among the chosen one for this unique crossover.

Quintet15 Horn1, EnjoyTheMusic Best of 2018 Award

“B&W 801, Quad ESL-57, and KEF LS3-5a are a few legendary transducers that have served music and sound lovers alike on both sides of the microphone for decades. But none of them is new. And none offer up a new level of both technical brilliance and visual appeal to go along with spine tingling “you are there” sound quality. I speak of the new PureAudioProject Quintet15 Horn1 Modular Open Baffle Loudspeakers – a sonorous triumph of aesthetics and technique.”

Steven Rochlin and Jeremy Kipnis, EnjoyTheMusic Best of 2018 Award


“To my ears, “done right” describes the PureAudioProject’s Quintet15 Horn1 Modular Open Baffle Loudspeakers I auditioned at CAF… full, large, relaxed, open, and naturally detailed. No hi-fi unnaturalness.”,

Herb Reichert, Stereophile


“PureAudioProject’s latest loudspeaker design, the Quintet15 Horn1 takes its place among a cherished handful of great examples of speakers that are true music instruments.” Jeremy Kipnis, January 2018  With a stated sensitivity above 95dB, the Quintet 15’s sounded nearly as airy and easy on these ears as did the big and outrageous Stein Music horns that debuted at the High End show this past spring. What was even more impressive was the new and, for me, totally unheard of Whammerdyne Truth 4 watt SE amplifier ($16k) that powered the system to realistic sound levels. One thing’s for certain: there’s a lot to be had here for under $10k and the PureAudioProject Quintet 15 may be one of the best values in high-end audio in the here and now.”
