A revolutionary drive unit material is only the start of the technological innovations that make this new Quad subwoofer a fine addition to any surround or stereo system.

The 'tri-lam' cone is a composite construction comprision of a hydraulically moulded and thermoset lamination of three materials.  The inner layer is bi-directional weave carbon fibre, the two outer layers are bi-directional weave glass fibre.  The outer rim of the cone incorporates rim-edge stiffening within the design.  The resulting cone is extremely rigid and lightweight, ensuring very low energy losses, even at extremes of volume, and without the delays associated with high-mass paper pulp or plastic cones commonly used in subwoofer drivers.

Further innovations include a powerful 300WRMS amplifier module coupled with a brand new filter stage.  A microprocessor controlled filter section has been developed adjustable between 35 and 85Hz in 10Hz steps - each having a discrete path for the cleanest signal possible.

A full function remote control allows the user to calibrate the subwoofer (crossover, volume and phase) from the listening position and store up to four settings in the memory, which can be recalled at the touch of a button.  Finished in the same chouce of high quality piano lacquered veneers as the existing L-series models the L2-subwoofer is as attractive a piece of furniture as it is accomplished as a reference subwoofer.
