Overview
Not a hulking cabinet, this Bowers & Wilkins sub packs an eight inch driver and its own amplifier into a box under one cubic foot. It connects by line or speaker level, so it pairs with receivers or stereo amplifiers.
Small size with fast, tight bass fills out bookshelf speakers without dominating the room. A small driver limits the deepest, loudest bass in large spaces.
Who it's for
Apartment and den listeners with B&W bookshelf or satellite speakers get a matching bass extension. Owners of big rooms or bass-heavy movie setups should consider a larger sub.
Pros and cons
- Very compact cabinet
- Built-in power amplifier
- Several connection options
- Matches 600 Series finishes
- Limited output for large rooms
- Frequency range not listed
- No wireless connection
- Heavy for its size
Performance notes
Bass quality comes from the front-firing driver paired with a Class D amplifier, which favors speed and control over sheer depth. Room size matters, as a compact box reaches its limits sooner in large spaces.
