Abstract
A stereo loudspeaker system includes left and right loudspeaker cabinets each having a woofer mounted off center on the front baffle and tweeters mounted in front of the woofer with the axis of each tweeter at an angle to that of the woofer. Each cabinet includes a crossover network that intercouples the woofer and tweeter and controls the phasing of the tweeter with respect to the woofer to steer the radiation maximum of lower treble frequencies along an axis skewed from the fore-aft axis of the woofer. Left and right loudspeakers of the stereo system have symmetrical, mirror-image, crossfired, acoustic radiation patterns.
