Quatro Wood CT

Vandersteen Audio introduces the Quatro Wood CT, the latest evolution in speaker technology and sound quality to derive from the research & development efforts that delivered the patented carbon-fiber Perfect-Piston drivers used in the flagship Model 7. While the Perfect-Piston Tweeter used in the Model 7 is the fully embodied deal of high-frequency purity and resolution, the Quatro Wood CT (Carbon Tweeter) features the superb Carbon Tweeter from the renowned Model 5A Carbon.

Vandersteen Audio has done its best to photograph these wood finishes on each product page, but please know that while the woods we receive from our vendors are unfailingly high in quality, no two pieces of wood are ever exactly alike. This is dictated by nature. We promise that your speakers will look gorgeous, but not that they will precisely match the photos you see on our website or on our dealers’ in-store demo speakers.

" ... the Quatro (Wood CT)s fit the bill for musicality, extended frequency response, dynamically spot on, and being drop-dead attractive to look at. Thanks, Richard. Much love to you and all at Vandersteen ... A real keeper." -Dave Clark, Editor Positive Feedback Online

Vandersteen Audio introduces the Quatro Wood CT, the latest evolution in speaker technology and sound quality to derive from the research & development efforts that delivered the patented carbon-fiber Perfect-Piston drivers used in the flagship Model 7. While the Perfect-Piston Tweeter used in the Model 7 is the fully embodied deal of high-frequency purity and resolution, the Quatro Wood CT (Carbon Tweeter) features the superb Carbon Tweeter from the renowned Model 5A Carbon.

Carbon driver cones offer the pistonic linearity of metal drivers without the unnatural sonic colorations inherent in metal drivers. Employing a carbon tweeter allows the Quatro Wood CT to deliver an astonishing amount of the air, space and natural purity previously heard only in the Model 5A Carbon and the Model 7.

Like all Vandersteen speakers, the Quatro Wood CT is a time- and phase-correct loudspeaker, made in the USA. Because such great demands are placed on the drivers in Vandersteen’s first-order speaker designs, all of the Quatro Wood CT’s drivers are the kind of highly advanced transducers typically found in cost-no-object designs. Vandersteen’s patented, Reflection-Free 4.5” midrange driver breaks up energy from behind the driver before it can pass directly back into the room and to the listener’s ears. The 6.5” Tri-Woven woofer offers superior transient response and definition in the crucial lower-midrange/midbass frequencies. 

Of course, the Quatro Wood CT also provides much of the performance and versatility of Vandersteen’s top-end powered-bass speakers in an attractive and compact form factor. The Quatro Wood CT’s foundation is its powered subwoofer section. Each speaker is equipped with dual 8” subwoofers powered by custom-tailored amplifiers that work in conjunction with passive, first-order (6dB/octave) 100Hz high-pass filters and 11-band EQ for the ultimate in-room performance optimization.

High-pass filtering allows the main amplifier to perform better, unburdened of reproducing deep bass, and is also the only way to ensure flat frequency response at the crossover to the powered subwoofer. Passive speaker designs always require placement compromises between the areas in the room where the imaging is typically best (farther out in the room) and where the bass is best (closer to the walls for boundary reinforcement). In Vandersteen’s powered-bass speakers the speaker can be placed out in the room where it images best, while the 11-band EQ ensures powerful but perfectly tailored in-room bass performance. The best of all things.   

The impedance-compensated crossovers are ultra-high-performance designs featuring extreme-quality parts and individually tuned in an anechoic chamber. Vandersteen’s Minimum Baffle enclosures ensure maximum rigidity free of time-smearing reflections and diffraction.

All of this technology allows the Quatro Wood CT to offer the kind of exceptional resolution, imaging, and natural musicality Vandersteens are known for, with deep and powerful yet tuneful bass, virtually anywhere in any room.

    I played the Quatros for my partner (female) last night and she was basically blown away.  She doesn’t care about anything technical for audio, but she sure liked the sound.  She said there weren't many new layers of music from my decent prior setup. However, the overall upgrade was like night and day, she found.

    Paraphrasing spontaneous reactions… she said the speakers sounded like they weren’t there.  The music was so much “bigger” without being louder.  The music didn’t have any parts; it just sounded balanced and even.  Bass was deeper and stronger but was just part of the coherent picture, not a separate feature.  ‘It just sounds beautiful, quiet and so very clear.”  Words from a non-audiophile speak volumes!

    'I purchased Vandersteen Quatro Wood CT speakers after auditioning dozens of others,  including Wilson, Magico, Focal, Harbeth, Klipsch, Sonos Faber, etc.,--the Vandersteen's didn't stun me, they didn't knock me over the head, or attempt to color my world with a particular 'brand sound,' they simply captivated me and sucked me into the profundity of great music if well recorded regardless of genre. They activate my imagination and produce the experience of what it might have been like to be there in the studio, arena, theater, etc. I couldn't be happier with my choice. And thanks to John Rutan and the gang at Audio Connection for being such helpful  audio sherpas.'

    Regarding Audio Connection--I'm so lucky and grateful to have that great gang of misfits living nearby in Verona, New Jersey. Big thanks in particular to Nick and Samir for providing set up expertise.

    I'm only one month in with this new system but already I can tell you the music flowing out of the Quatros has brought so much joy and pleasure to me and my family. 

    I also think it's super cool how directly involved Richard Vandersteen is with his customers and fans, not only on this forum, but via email, telephone, in person, etc. I have a sense this isn't common among other high profile speaker designers.

    "That's primarily what I want from a pair of loudspeakers—not deep bass (which these Vandersteens do have); not wide dynamics (at which the Wood CTs excel); not clean, uncolored mids and highs (something the Vandersteens readily offer); but a stereo virtual reality engine to connect me with the music I want [to] listen to. On that ground, a pair of Vandersteen's Quatro CTs scores big-time."

    "They (Quatro Woods) delivered a huge, detailed, transparent soundstage that gave me all of the music without obscuring any of its details. And I found the speaker's representations of female voices, stringed instruments, and ambient detail about as good as those of any speaker I've ever heard ..."

    " ... the Quatros' organizational talents, and their ability to project three-dimensional spaces and array precisely focused, solid images within those spaces, bested those of every other speaker I've reviewed, including my reference Wilson MAXX2s, which sound somewhat vague by comparison."
