ABSTRACT:
A loudspeaker system using ribbon transducer elements wherein the ribbon elements of the high and mid-range transducer units form a plurality of conductive circuits separated by spaces, or cuts, therebetween which have substantially smooth, undulating wave forms. The magnetic circuit return paths thereof are arranged so as to be remote from and out of the transmitting paths of the acoustic signals generated at such units and the surfaces of the magnetic circuit components and a baffle structure associated therewith are shaped to reduce diffraction effects in the acoustic signals therefrom. A woofer ribbon element has a plurality of interconnected conductive circuit regions to form a generally serpentine shaped circuit, which regions are separated by channels, or cuts, each of which has a smooth, undulating wave form.
