The Chartwell Sub 6 designed by Derek Hughes is a

passive sub-woofer, designed to be used in conjunction with the Graham LS3/5and LS3/5A, but also applicable to other designs of similar sensitivity and impedance.

​

It is designed to be used under the main speakers, and has a front facing reflex port. It has connections on the rear for the input from the amplifier and output to the main speakers.

​

There is also provision for feet or spikes to be fitted into the base of the cabinet.

​

The crossover uses high quality components, air core inductors for zero saturation distortion and Polypropylene capacitors.
