# Bowers & Wilkins CT SW10 Custom Theater Passive Subwoofer – USD $535

The CT SW10 is a solid mid-tier custom install sub, purpose-built for integration into home theater systems rather than standalone use. At USD $535, this asking price sits comfortably above your database median of USD $483 but well within the 75th percentile ceiling of USD $1,930—so it's fairly positioned. Used B&W subs in this class typically move between USD $400–$800 depending on condition and age, making this a reasonable ask that shouldn't raise red flags. The premium over baseline reflects the custom-install pedigree and relatively tight build quality.

Before committing, confirm the amplifier is functional (passive subs rely entirely on external amp power, so a dead or flaky amp makes it a paperweight). Verify the driver cone for tears, surround degradation, or signs of water exposure—common failure points in used theater subs. Ask about age and whether it's been stored in stable temperature/humidity; the crossover internals can drift or fail after years of thermal cycling. Ideally, request a photo showing it powered up with a test tone, and confirm any mounting brackets or isolation feet are included.

Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.

About Bowers & Wilkins

Bowers & Wilkins traces its origins to 1966 in Worthing, West Sussex, England, when John Bowers, a passionate audio enthusiast and former electronics shop owner, founded the company with the help of a £10,000 bequest from a satisfied customer, Miss Knight. Bowers, who had honed his speaker-building skills as a hobby while running a radio and TV rental shop with partner Roy Wilkins, launched the venture from the back of that very shop. This modest beginning fueled a relentless pursuit of audio perfection, establishing Bowers & Wilkins as a British icon in high-fidelity sound reproduction.

The brand excels in premium loudspeakers, from flagship studio monitors like the legendary 801 series—adopted by Abbey Road Studios in 1979—to accessible Domestic Monitor lines such as the enduring 600 Series. Its portfolio has expanded to encompass high-end headphones, including the iconic P5 and Zeppelin designs, alongside wireless speakers and formation systems, all emphasizing advanced driver technology, precision cabinetry, and Continuum cones for unparalleled clarity.

Positioned firmly in the high-end market, Bowers & Wilkins commands respect among discerning audiophiles for its engineering excellence, musical accuracy, and heritage of innovation. Far from mid-tier or niche, it rivals the elite, blending cutting-edge research from facilities like Steyning with a reputation for reference-grade performance that defines luxury hi-fi.
