Bowers & Wilkins DB4S Subwoofer
DB4S is the single-driver subwoofer in the DB range, with a more conventional cabinet and a strong focus on home cinema impact. Bowers & Wilkins positions it as a natural partner for the 700 Series.
Its 10-inch Aerofoil cone is powered by digital amplification and supported by a digital preamplifier with Dynamic EQ. The dedicated control app makes calibration and correction easier than relying on guesswork at the back of the cabinet.
It is a good fit when you want a substantial lift in low-frequency weight while keeping the system visually and technically straightforward.
