Bowers & Wilkins DB1D

The DB1D delivers exceptionally deep, controlled bass from a relatively compact cabinet. The reviewer heard usable output down to 12Hz, called its infra-bass powerful and accurate, and described it as going lower than any same-sized subwoofer they had heard.

The review reports that automatic room equalisation makes the DB1D far less sensitive to placement, a useful real-world benefit when blending it into a system. Its measured response was also described as exceptionally flat across the pass-band, though the review offers little direct listening commentary on whether the sub fully disappears with main speakers.

Bass is described as almost surreal in speed, with the DB1D remaining composed when challenged by demanding low-frequency material. The reviewer says it did not flinch, while also highlighting high SPL capability, low distortion and the balanced drivers' reduced cabinet vibration.

The review sample was described as flawlessly finished in superb piano-black lacquer. Bowers & Wilkins' stiff Aerofoil drivers and balanced opposing-driver layout suggest a carefully engineered enclosure, although the review says little about long-term durability.

App control covers volume, crossover frequency, phase and selectable high-pass slopes, giving owners substantial setup control from the listening position. Automatic room EQ and the ability to choose equalised, flat or tailored responses make the DB1D notably flexible for different rooms and preferences.

At around $7,200, the DB1D is firmly a premium subwoofer, with performance aimed at demanding high-end systems. The review is strongly enthusiastic about its sound and measured performance, but does not directly compare its price with competing models or explicitly assess value.
