Bowers & Wilkins' highest-end subwoofer, intended to be paired with their 800-Series speakers. It features a 1,000W amplifier and dual/opposing 12" drivers. To put it bluntly, the piece is built like a fortress and sounds phenomenal. I have personally set a champagne glass on top through the roughest of audio patches, and there was not a ripple in the glass -- despite the room shaking.
This piece does not have the original B&W box, but I do have all accessories and covers that came with it brand new. From common dusting and polishing, the finish has expected hairline wear, but otherwise no cosmetic damage. Functionally, all is in working order and sounds great.
While local pickup would be preferred, I am willing to ship if necessary. However, I am unsure about packing/shipping costs at this time.
