<p>A center channel loudspeaker system for use with a Dolby four channel sound system is presented. A first loudspeaker (18) is mounted at the front of an enclosure (10). Second and third loudspeakers (12, 14), each having a larger cone size than the first loudspeaker (18), and having a lower frequency range than the first loudspeaker (18), are mounted at the front of the enclosure (10) one on each side of the first loudspeaker (18), at an angle of approximately 40 degrees in the vertical plane back from the first loudspeaker (18). With this arrangement, destructive cancellation of the sound emanating from the closely spaced center channel loudspeakers is minimized.</p> |
