| For big sound in smaller spaces, you canʼt 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® 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 slamm
