Сабвуферы — B&W (Bowers & Wilkins) DB4S

The DB4S is a powered subwoofer from Bowers & Wilkins, built as the most compact model in the brand's DB series with a capable 10-inch Aerofoil cone driver. This active closed-box design is specifically styled to match B&W's 700 Series speakers, and uses the same rigid, lightweight, variable-thickness Aerofoil cone material found in the flagship 800 Series Diamond loudspeakers.

Key specs that matter

Frequency range is -6dB at 8.5Hz and 500Hz, with a rated frequency response of 10Hz to 350Hz at -3dB, centred on level at 100Hz - the 10Hz low-end figure is exceptional, reaching well below the conventional 20Hz threshold most listeners can consciously perceive. Maximum power output is 1000W from a digital class D amplifier. Rated power consumption at one-eighth of rated power is 195W, with standby consumption under 0.5W. Two RCA and two XLR inputs are provided, at 10 kOhm and 20 kOhm input impedance respectively. Signal-to-noise ratio is 82 dB. At 377 x 360 x 368 mm and 26kg (57.3 lb), this is a compact sealed-enclosure design available in Gloss Black, Satin White or Rosenut finishes.

Sound and use context

Expect solid, dramatic bass with genuine precision, control and authority thanks to the digital amplification and rigid Aerofoil cone construction - despite its relatively modest dimensions compared with larger DB-series models, this subwoofer delivers confident, dense and deep bass suited to a smaller room without sacrificing the low-frequency extension serious cinema or music playback demands.

Pairing

A dedicated smartphone app entirely replaces physical controls, letting a buyer select RCA or XLR input, stereo or LFE connection mode, input gain, equalisation presets (flat, music, movie or user), and run an automatic room-correction routine using the phone's own microphone at seven measurement points around the room.

Alternatives

Bowers & Wilkins' DB3D sits one tier above this model in the brand's powered subwoofer range with twin 8-inch Aerofoil drivers for more low-end power, worth the further investment if this DB4S's already exceptional depth and control still leave ambitions for even greater output in a larger room. Included accessories cover a detachable grille, four decoupling feet, four rubber feet and four spikes, giving genuine flexibility for isolating the cabinet on different floor surfaces during setup.
