Vandersteen Treo Loudspeakers

The Treo is essentially a passive version of the original Quatro Wood, 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. But the Treo is also a modern take on the legendary Model 2, 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.

Vandersteen’s 4.5” Reflection-Free™ Midrange carried a US patent for over 20 years, and the essential design is still the heart of all Vandersteen speakers. Typical midrange drivers are backed by a large, round magnet structure that’s nearly as big around as the driver cone itself. Because drivers cones emit as much energy backward as forward this “back wave” of sonic energy reflects off the magnet structure and arrives at the listener’s ears in time with the primary signal, smearing the timing of the music and creating sonic confusion. Vandersteen’s Reflection-Free midrange avoids this time-domain distortion by using an open back with a cylindrical magnet structure that allows the back wave to be broken up and diffused inside the speaker cabinet so it doesn’t smear the signal reaching the listener’s ears. The result is a pure and open midrange with true Dimensional Purity …
