ABSTRACT:
A speaker enclosure having a rear bass-reflex chamber and a forward mid-range chamber formed within a substantially rectangular housing. A tunnel-bass port is formed in the bottom section of the front wall of the enclosure, the bottom section being angularly disposed and arranged to communicate with the rear bass-reflex chamber. The upper section of the front wall is provided with a mid-range port that communicates with a mid-range chamber. A bass speaker is mounted to a central partition which divides and separates the bass and mid-range chambers. A sealed, self-contained, mid-range speaker is also mounted to the central partition and arranged to disperse mid-range tones by way of the mid-range chamber, so as to exit the mid-range port in unison with the high-frequency tones produced by a tweeter mounted to the upper front wall section. Thus, each speaker disperses its own frequency range in a clear and distinct manner.
