RC -4A Reference BiPolar Surround is our largest rear surround and the first speaker system that properly delivers all of the surround information found in Dolby Digital and DTS sound-tracks. Key to the performance of the RC– 4 is the optimal integration of reference wool/carbon quiet cone™woofers and a high quality MDF enclosure coupled with a driver orientation (front and side firing mid/woofers and tweeters ) that allows for easy wall mounting/ positioning with respect to any listener. Midrange/bass is radiated in a symmetrical arc that approaches 120 deg. laterally. High frequencies approach 180 deg. as an array of tweeters projects sound in a wide pattern .
