Bowers & Wilkins ASW608
Active Subwoofer
The Bowers & Wilkins ASW608 is the most compact model in the company’s ASW Series, designed to deliver deep, controlled bass from a surprisingly small enclosure. Ideal for smaller listening rooms, apartments, or discreet home cinema installations, it combines a high-performance sealed cabinet design with a powerful amplifier to produce bass that is both musical and impactful.
At its core is an 8-inch (200mm) long-throw driver featuring a paper and Aramid fibre cone. This lightweight yet rigid construction allows the driver to move significant volumes of air while maintaining excellent control, resulting in fast, articulate bass with minimal distortion. The sealed (closed-box) cabinet further enhances accuracy by prioritising transient response over sheer output, making the ASW608 equally suited to music and film soundtracks.
Powering the driver is a 200-watt amplifier, providing ample headroom for dynamic performance while maintaining precision at both low and high listening levels. Comprehensive rear-panel controls include adjustable volume, variable low-pass crossover, phase switch, bass extension settings and bass roll-off alignment, allowing the subwoofer to integrate seamlessly with a wide range of loudspeakers. Auto standby and a 12V trigger input make it convenient to incorporate into dedicated home cinema systems.
Despite its compact dimensions of just 260 x 260 x 305mm (excluding grille and feet), the ASW608 reaches down to around 23Hz, providing convincing low-frequency extension for both stereo and surround sound applications. It offers line-level RCA inputs, speaker-level inputs and a 12V trigger, making it compatible with a broad range of amplifiers and AV receivers.
Finished in Matte Black or Matte White, the Bowers & Wilkins ASW608 blends easily into modern interiors while delivering performance that exceeds expectations for its size. It is an excellent choice for listeners seeking tight, accurate and room-friendly bass without the footprint of a larger subwoofer.
