The Subwoofer is a high output low frequency loudspeaker system designed to provide superior output and fidelity for extended low frequency audio reproduction. It incorporates our proprietary tuned, damped, OPTM alignment, providing greater output and less distortion as compared to standard venting. Artefacts and vent turbulence, even at extreme levels, are reduced. This makes the subwoofer an ideal choice for high level systems requiring stability and reliability under the most demanding long term use. Designed for portable use, the subwoofer is constructed from 18mm Baltic birch plywood and features a durable and attractive black Ro Tex™ finish, durable steel grille, Integral handles and a stand adapter.
