DIAMOND SERIES SUBWOOFERS

Subwoofers designed for use in closed or band-pass enclosures. The soft rubber suspension and voice coil allows a very long cone movement which is effectively controlled by the dual strong magnets. The result is a very tight low bass reproduction. The Aluminium Diamond cut chassis is extremely stiff.
