ABSTRACT:
A loudspeaker (10) has speaker mounting walls (11 and 12) joined at an apex angle (15) of 70.degree. or less, with a pair of tweeters (20) mounted as close to the apex as possible and a pair of woofers (25), arranged below the tweeters, and also mounted as close to the apex as possible. The width spanned by tweeter pair (20), from a viewpoint in front of apex (15), is approximately equal to the frontal width of either tweeter. Similarly, the width spanned by woofer pair (25), from a viewpoint in front of apex (15), is approximately equal to the frontal width of either woofer. The geometry of this mounting arrangement produces even acoustic intensity throughout a wide angle around both sides of the apex and preserves stereo identity by having the sound emanate from an apparently small source.
