ABSTRACT:
A loudspeaker system has an elliptical stepped mid-range horn above and coplanar with a flared mid-bass horn having disposed therein a pair of tweeters on sidewalls thereof and a woofer in a backwall thereof. The back of the woofer communicates with a folded low frequency bass horn such that low frequency response is loaded from the rear of the diaphram for the woofer driver, thereby eliminating the necessity for further amplification and drivers to obtain fidelity in low frequency response. The low frequency bass section defines a convoluted path for the sound which comes from the interior structure of a folded horn thus creating an acoustical boost for low frequency sound.
