ABSTRACT:
The loudspeaker includes a front panel of expanded polystyrene resiliently connected to side walls of the speaker enclosure. A standard loudspeaker is connected to the front panel, and there is a small diffuser cone concentric with the standard cone. The front panel is driven by the standard cone to reproduce low and medium frequencies and the diffuser cone reproduces high frequencies. Both speakers are driven by a common driver fixed to a rear panel or cross-beam of the enclosure.
