The SubSeries BP8 is a powered subwoofer from PSB's SubSeries range, positioned below the larger SubSeries 350. PSB's SubSeries range serves as the brand's dedicated bass-reinforcement catalogue, offering capable subwoofers to complement the brand's Imagine and Synchrony main speaker ranges.
Position in line
It sits below the SubSeries 350 and near the BP7 in PSB's subwoofer hierarchy. This positioning below the larger 350 suggests the BP8 serves buyers with a more modest room or main speaker system, trading some output for a more accessible price and compact cabinet.
Key specs that matter
Rated response is 25 Hz to 150 Hz. The built-in amplifier is rated at 500 W, a solid figure for the cabinet size. At 33.0 x 33.0 x 35.6 cm and 19.1 kg it is a moderately sized cabinet, its roughly cube-shaped proportions offering flexible corner or wall placement in most rooms.
Sound and use context
Expect solid, well-controlled bass reinforcement suited to a small to medium room - a capable performer reflecting PSB's broader measurement-focused engineering philosophy applied specifically to bass reinforcement.
Pairing
Standard line-level or speaker-level subwoofer inputs work with any stereo or AV receiver offering a subwoofer output, so integration should present no particular challenge.
Alternatives
The SubSeries 350 sits above this model in PSB's range for more output; the BP7 sits nearby as a related model, worth comparing directly on cabinet size and specific amplifier power before choosing between these closely positioned PSB subwoofers. PSB broader SubSeries range gives buyers a clear ladder of subwoofer options to match against room size and main speaker scale, and a dealer conversation about the specific main speakers already owned helps clarify which tier makes the most sense. Corner or wall placement remains the simplest way to reinforce output from a subwoofer of this kind. A phase switch, where fitted, is worth experimenting with to find the smoothest blend with the main speakers. Overall this remains a sensible, accessible choice within PSB broader subwoofer catalogue. A dedicated subwoofer cable run also helps avoid any hum introduced by a shared or undersized cable. A dealer visit remains the simplest way to compare current pricing between the BP8 and BP7 models. Overall this remains a capable, accessible choice within PSB dedicated subwoofer catalogue.
