Power packed

DB3D's tight, powerful, dramatic bass and compact size make it the perfect match for the 804 D4 and 805 D4 speakers.

The perfect match

DB3D's ultra-rigid low-resonance enclosure comes in three finishes to match 800 Series Diamond and 700 Series loudspeakers.

More bass, less space

The compact model packs a mighty punch. Controllable, dramatic bass from a subwoofer so small it fits almost anywhere: DB3D is a space-saving high-performance design.

Nimble and powerful

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

A question of balance

The back-to-back (opposed) drivers cancel out cabinet resonances, ensuring all that power is used to create room-shaking bass, not wasted vibrations.

The digital advantage
Digital amplification is cool-running and energy efficient, even when working hard, while Dynamic EQ and Room EQ ensure a precise sound for music and movies.

Take control
By placing control in the palm of your hand, the B&w subwoofer only makes the DB Series subwoofers a snap to see and it also helps maximize your sound quality.

Completely belying its compact dimensions, the DB3D is a miniature powerhouse and plumb depths of LF that no box of these dimensions has any right to. The performance is super-thigh-speed fast and carries a weighty punch with LFE and two-channel stereo.
