ABSTRACT:
A dual tweeter speaker, wherein the tweeters are spaced far apart, is provided. The loudspeaker system includes a woofer and two tweeters, which are arranged so they reduce interference with sound waves emitted by the woofer. The spaced apart tweeters provide an improved stereo imaging range. The tweeters can also use a low cross-over frequency, so that they can provide both midrange and high frequencies.
