<p>The loudspeaker system is housed in a rectangular box. The four lateral surfaces (2-4) of the box have the same dimensions, and the top (7) is square. The box consists of tubular, hemispherical or any other shapes which favour uniform mixing of all frequencies, with their axially symmetrical radiation. One or more tweeters (5) are mounted in the top (7) or in any other box part, radiating vertically upward. One or more tweeters (5) are mounted in each of the side walls (2-4) or any other box part. Loudspeakers in the side walls (2-4), in the top (7) or in any other box part ensure uniform mixing of all frequencies, with their axially symmetrical radiation.</p> |
