<p>An improved sound reinforcement enclosure which incorporates a cone-type loudspeaker (75) operating into a generally cylindrical channel extending from the perimeter of the cone (24) to free air. A central member (36) is coaxially mounted within this channel, the central member (36) having rear surfaces (35) substantially parallel to the surface of the cone (24) and external surfaces (34) which, with the internal surfaces (32) of the channel form an annular region (40), the central member (36) also having at least one coaxial internal passage (41) forming a concentric horn flare. Methods of coaxially mounting a high-frequency compression driver (10) behind the magnet assembly (23) of the loudspeaker (75) and of mounting a second loudspeaker (65) internally in an enclosure are also disclosed.</p> |
