Engineered to seamlessly pair with the Bowers & Wilkins 700 Series, the DB4S powered subwoofer marries cutting-edge innovation and the company's traditional, sonically focused engineering methods to offer performance that dramatically elevates both stereo and home-theater systems. Relying on the strengths of a 1,000-watt Hypex amplifier, digital preamplifier with dynamic EQ, and sealed cabinet design, the 14.8 x 14.1 x 14.5-inch (HWD) DB4S reaches down to 10Hz with uncanny accuracy, control, and presence. If you crave punch, dynamics, and fullness, you've come to the right place.
Yes, we all know setting up and dialing a subwoofer can be a pain. Which is another reason why DB4S knocks it out of the park. Free of any rear-panel controls, DB4S operates entirely via dedicated app control by way of your smart device. Calibrations and corrections are made right on your phone. In a flash, DB4S snaps to your commands and customizes settings tailored for your room. The intuitive app even uses your device's microphone to take aural measurements and apply optimizations. Too cool!
Lest we forget, the elegant finished and irresistibly attractive DB4S features a 10-inch woofer comprised of Aerofoil – the rigid, lightweight, and variably thick material found in Bowers & Wilkins' 800 Series Diamond. Now you know why distortion is never an issue with DB4S. For connectivity ease, the 57.3-pound unit includes a pair of XLR and two RCA inputs. A detachable grille, four decoupling feet, four rubber feet, four spikes and a cleaning cloth.
