The SUB3 is a sub-woofer 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 35Hz in a compact enclosure.
