Vandersteen’s new Treo and Treo CT Speakers

The Vandersteen Audio speaker lineup continues to evolve as a result of the research & development efforts that delivered the patented carbon-fiber Perfect-Piston™ drivers used in the flagship Model 7.Vandersteen’s Treo loudspeaker is now available in an optional Treo CT version (Carbon Tweeter), which is a $1,500 upgrade that features the superb Carbon Tweeter from the renowned Model 5A Carbon.  The Treo has an MSRP of $6,490 per pair and the CT version, $7,995 per pair.

Carbon driver cones offer the pistonic linearity of metal drivers without the unnatural sonic colorations inherent in metal drivers. While the Perfect-Piston Tweeter used in the flagship Model 7 is the fully embodied ideal of high-frequency purity and resolution, the Treo CT delivers a surprising amount of the air, space and natural purity previously heard only in Vandersteen’s top speaker models: the Quatro Wood CT, Model 5A Carbon and the Model 7.

The Treo is essentially a passive version of the Quatro Wood CT, sharing the same driver complement sans the powered-bass system. It too is offered in an array of wood finishes in a strikingly attractive form factor.  Like the legendary Model 2, the Treo is a paragon of cost-effective performance that’s made in the USA, but in an elegant outer package.

The Treo is a time- and phase-correct full-range loudspeaker. Because such great demands are placed on the drivers in Vandersteen’s first-order speaker designs, the Treo’s drivers are the kind of highly advanced transducers typically found in cost-no-object designs. The proprietary transmission-line loaded tweeter and Vandersteen’s proprietary Reflection-Free 4.5” midrange driver break up energy from behind these drivers before they 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, with the bass foundation supplied by the ported, carbon-loaded 8” woofer with an ultra-long motor assembly.

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 Treos to offer the kind of exceptional resolution, imaging and natural musicality Vandersteens are known for.
