Description
The VR1, VR2, and VR3 compact floorstanding speaker systems and the VRB compact bookshelf speaker system deliver the kind
of powerful, impressive sound usually associated only with much larger, more expensive speakers.
The high-performance VRC is a timbre-matched center channel speaker that is a perfect compliment to any of the VR floorstanding
models in your home theater system. The VRC’s three-way design delivers extremely wide horizontal dispersion and exceptionally
high power handling capability.
All three VR floorstanding models feature dual woofers for deep, authoritative bass response and low distortion. The placement
of the woofers on the baffle has been chosen with extreme care and precision, and it provides two very specific, clearly audible
benefits: First, by separating the woofers by a precisely calculated distance, the internal "pipe organ" standing wave—common
to all columnar-type enclosures that have their bass drivers closely grouped at one end of the cabinet—is reduced to the point
of audible insignificance. The result is less midrange coloration and a commensurate increase in clarity and detail.
