Bowers & Wilkins ASW610 Subwoofer presents a very happy medium between the more diminutive ASW608 and the all-out power of the ASW610XP. Its long-throw 250 mm driver allows the ASW610 to move the large volumes of air needed for high-quality low-frequency output, and its audiophile-standard 200 Watts Class D amplifier keeps the compact unit running cool, even when the music or movie action is whipping up a storm. In all of the 600 Series subwoofers, the bass driver diaphragms are constructed from a rugged, finely-tuned mix of paper pulp, Kevlar® fibres and resin, which provides the stiffness needed to withstand the tremendous physical forces exerted by the voice coil and pressures inside the cabinet. Ultra-solid construction delivers slamming bass, drum kicks, and special movie effects. Deformation is minimised; bass precision, power and enjoyment are maximised.
