1000 watts of power supplied to a 10" driver.  Just awesome.

A powerful, classically styled single driver subwoofer that's a perfect match for the Bowers & Wilkins 700 Series.

Solid, dramatic bass is delivered through the rigidity and lightness of the uniquely-shaped, variable thickness Aerofoil™ cone.

DB4S uses a digital preamplifier featuring Dynamic EQ, for optimized audio performance across the available frequency range.

From Home Cinema Choice magazine UK...

"The subwoofer's most obvious contribution (apart 
from giving explosions compelling weight and violence 
and indulging the mixing engineer’s wildest infra-bass fantasies) is its seductively sumptuous yet supple quality with music. Bruno Mars’ Finesse (CD) has never sounded more full-on or, indeed, dripping in finesse. Tempo and rhythm, so often the downfall of AV speaker systems, 
is truly nailed here."
