Description

The Graham Audio SUB3 is a subwoofer designed to work with the Chartwell LS3/5 and LS3/5A from Graham Audio, but it is also applicable to other designs of similar sensitivity and impedance. Designed by Derek Hughes, it employs a novel bass loading technique to achieve extension down to 35 Hz in a compact enclosure.

They are supplied in pairs, and are designed to be placed near to the rear wall, while the main loudspeakers remain in their usual ‘free space’ position. Output is via the front-facing reflex port.

There are 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 to the base of the cabinet. Being passive, there are no controls to misadjust – the system is designed to be “plug and play”.

The crossover uses high quality components, including air-cored inductors for zero saturation distortion and polypropylene capacitors. The system crosses over at 100 Hz, and in doing so, relieves the LS3/5 or LS3/5A of energy frequencies below this point. This will allow the system to reach greater replay volumes, providing there are adequate reserves in the amplifier used.
