Bowers & Wilkins 800 Diamond Series loudspeakers deserve to be partnered with an equally high-end woofer. Which is why the Brit brand designed the DB1 – a 2 x 12-inch driver behemoth fed by a 1,000W amp.
The enclosure is sealed and sits upon a square plinth that houses the DSP system. If you turn the woofer over, you find you can disconnect some bolts, swivel the base through 90˚ and thus change the alignment of the woofer drivers with your room (you might want to go along a wall), while still keeping the display of the subwoofer showing. Neat.
