Abstract
This invention relates to a cabinet for audio reproduction speakers of the type which have a movable speaker cone mounted within a fixed speaker frame. The cabinet includes a plurality of external cabinet members juxtaposed to form a substantially rectangular cabinet having a rectangular void therein together with front and rear openings. Each of the external cabinet members is formed from a thin and acoustically stiff material for moving in a vibratile mode when energized. End sections of adjacent ones of the external cabinet members define therebetween isolation slots for permitting the independent vibratile mode of each of the external cabinet members. Nodal couplers span the isolation slots for transmitting vibratile energy between adjacent external cabinet members. The speakers are mounted within the rectangular void and are attached to at least one of the external cabinet members for coupling the vibrational energy from the frame of the speaker to the external cabinet member for energizing the vibrational mode thereof.
