The Bowers & Wilkins CT SW 10 is a subwoofer that is designed to work with the Bowers & Wilkins CT700 custom theatre speaker system. The 10" diameter paper & aramid fibre cone can produce the low frequencies required for a high-quality home theatre system. This material is specially designed to reduce standing waves minimise colouration & leaves transients unblurred. This results in a remarkably clear sound. The CT SW 10 can either provide the bass for your home cinema by itself or for the ultimate low-frequency experience you can daisy-chain several subwoofers together. Designed to be able to slot into your home theatre cabinetry this subwoofer is powered by the SA1000 amplifier which is available separately.
