B&W DB4S GBK powered subwoofer

Brilliant bass from Bowers & Wilkins Every now and then I'm tempted to buy a new subwoofer for my living room system, even though the last thing I need to do is bring home another new speaker. The Bowers & Wilkins DB4S has me thinking hard. So why does it have me intrigued? Well for starters, it carries the pedigree of Bowers & Wilkins' five decades of superb audio engineering. But beyond that, the DB4S packs a ridiculous amount of punch into a modestly sized enclosure. It's the kind of sub I would look forward to listening to every day. The DB4S pairs a 10" woofer with a 1,000 watt amp to fill your room with exceptionally deep and accurate bass (shown in gloss black). A look at what's inside (hint: it's really nice) The DB4S houses a 10" woofer driven by a 1,000 watt amp - all from a sub enclosure that measures a little more than a foot per side The woofer uses the same highly acclaimed Aerofoil(tm) driver material found in Bowers & Wilkins' 800 Series Diamond speakers (world-class floor-standing speakers that sell for $30,000 a pair). This light, ultra-stiff driver resists bending and flexing far more than conventional cones for incredibly deep and accurate bass with music and movie soundtracks. Precise and powerful This sub can provide delicate low-frequency details, as well as tirelessly pound out deep bass at high output levels with next to no distortion. It can shake the house, certainly. But this sub's forte is creating lifelike bass with precision and control - all the way down to a staggeringly low 10 Hz. This sub is an excellent complement to Bowers & Wilkins 700 Series models, including the 702 S2 . Tailor the sound to your room The DB4S is set up and controlled entirely from the Bowers & Wilkins DB Subwoofers app. Using your tablet or smartphone's microphone, the app takes bass measurements to find acoustic irregularities and automatically applies correction. The result? Smooth, well-balanced bass that's tailored to your specific room, furnishings
