For big sound in smaller spaces, you can't beat the ASW608, the most compact of the 600 Series subwoofers. Its long-throw 200mm driver allows the ASW608 to move the large volumes of air needed for high-quality low-frequency output, and its audiophile-standard 200W Class D amplifier keeps the 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 fibers 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 minimized; bass precision, power and enjoyment are maximized.
