MOTION PICTURE THEATER LOUDSPEAKER SYSTEM Abstract of the Disclosure A motion picture loudspeaker system is described in which the loudspeaker elements are integral with an acoustical boundary wall such that the characteristics of the vented for woofers are optimized. In order to overcome high reflection problems as sound from the tweeters is reflected by the motion picture screen and the acoustical boundary wall, frequency dependent acoustical absorptive material is attached to the wall to inhibit high frequency reflections with minimal effect on the bass optimization. The system includes the use of a steep slope crossover network having a crossover frequency such that there is a first order match of the woofer and tweeter dispersion at the crossover.
