Perfect for matching with any speaker, especially those in the new 700 Bowers and Wilkins range, The DB4S Subwoofer will provide booming bass that will add that extra wow factor to whatever you are watching or listening to.

The Bowers and Wilkins DB4S is the ideal partner for any speaker, especially those speakers within the new B&W 700 Series speakers. Recommended for home audio set-ups, these subwoofers are used for creating high-performance acoustics in home cinema environments, suitable for big and small living rooms.
This Bowers and Wilkins DB4S single driver subwoofer is powerful in its delivery and stunning in its design, offering both performance and beautiful aesthetics. It has been styled classically and comes with easy set-up instructions. The DBS4S single driver features an aerofoil cone design that employs the same technology found in the B&W 800 series Diamond speakers. The new aerofoil cone technology implements paper over carbon fibre. These subwoofer drivers provide much more amplification, with an impressive 1000w of digital amplification, rendered with high precision.
The DB4S subwoofer provides more authority and control, using a digital preamplifier that features industry-best Dynamic EQ for better performance no matter how scattered the frequency range is.  As well as Dynamic EQ, Room EQ ensures that the audio is suited for most living room configurations. DB4S has its own smartphone app too which offers easy control options, including adjusting the calibration and making quick corrections.
The B&W DB4S provides an impressive frequency range of 1x ø250mm (10in) Aerofoil cone bass and frequency response of 10Hz – 350Hz -3dB (centred on level at 100Hz). Along with the 195 w of rated Power consumption at 1/8th of rated power, this sound system is robust, withstanding any vibrations and ensuring a better overall listening experience. The standby power consumption of this speaker is less than 0.5W. The maximum power output of Bowers and Wilkins DB series subwoofer is 1000W and the signal to noise ratio remains 82 dB.
The drive unit technology used in DB4S is the same found in dual-driver DB2D. It has been fined tuned and is now offered in a new format as a single driver. The active closed box subwoofer system is 377mm in height, 360 mm in width and 368mm in depth – ideal to be combined with the Bowers & Wilkins 700 series loudspeakers. Available in multiple finishes including Rosenut, Gloss black and Satin White, the net weight of DBS4 is 26 kg. The colours too have been carefully chosen to complement the shades found in 700 Series.
