The six passive models in the QX MkII Series are joined by a new active subwoofer ­– the QX-12SUB MkII. Ideally suited to increase bass depth and impact with both movies and music the new sub incorporates a 30cm (12-inch) bass cone formed from a special pulp fibre formulation with excellent self-damping properties. This combines with a powerful 300W Class D amplifier and a ported rigidly braced enclosure to deliver an excellent combination of depth speed and impact.
