Serious bass power is developed in a compact cabinet thanks to the unit’s 500W amplifier, long-throw 250mm driver. Equipped with audiophile-standard Class D circuitry, the unit remains cool and efficient under pressure. 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.
