Here we have a very nice example of the Vandersteen 2Wq subwoofer. Rosewood, with grey cloth. I'm the second owner and it has worked flawlessly for me. Comes in original box, with owners manual, variable crossover and one pair 75Kohm crossovers.In Subwoofer engineering terms, system Q is the product of a complex mathematical equation derived from driver, electrical and enclosure parameters. In practical terms, it relates to the character of the bass response. A low Q subwoofer sounds highly damped and very tight. A high Q subwoofer produces a warm loose bass with more energy in the most audible bass range. The trick has always been to try to find the subwoofer with the Q that best matched your listening room and personal tastes. The 2Wq is the first subwoofer to feature adjustable Q.A bass contour control on the rear panel allows you to set the system Q anywhere from .5 (Slightly overdamped, i.e.., tight jazz sound) to 1.2 (Significantly underdamped, i.e., typical mass-market home theater sound). Somewhere in this wide range, you will find the perfect sonic complement for your room and taste. Conventional powered subwoofers receive their input signal directly from their crossover before the main amplifier. The sonic signature of the main amplifier that is an important part of the sound you hear from the full-range speakers is missing from the subwoofer. This causes blending and integration problems as the sonic characteristics of the system are different above and below the subwoofer crossover point. This deterioration of system coherence is why conventional subwoofers have never been totally accepted as part of ultra high-performance audio systems. The 2Wq uses a unique, innovative connection method that reduces the current demands on the main amplifier, but leaves the main amplifier in the signal path to the subwoofer. The system realizes the benefits of bi-amplification with absolute sonic continuity as the main amplifier ’s characteristics that are evident through the full-range speakers are maintained to the deepest bass, but with the power and control of the 2Wq ’s internal 300-watt amplifier. Been a great sub. If you are familiar with Vandersteen, you know the quality of this 80 pound behomoth.
