Loudspeaker system with broad image source with directionality control for the tweeter

Charles R. Barker

A loudspeaker system comprises a woofer in a front panel, a midrange driver facing to the front and a tweeter in a corner panel separated from the midrange driver by the woofer and pointing to the front and side with a crossover network arranged to energize at least the midrange and tweeter in an overlapping frequency range. An adjustable deflector is positioned near the tweeter. Another embodiment of the invention has only a woofer and a tweeter on only one corner panel with the crossover network arranged to energize the two in a common frequency range that is greater than an octave.
