A speaker system includes a rigid elongate speaker enclosure having first and second ends, a speaker driver mounted at the first end and directed outward, and a sound dispersion assembly mounted over the speaker driver. The speaker enclosure has a wall between the first and second ends which is provided with a plurality of undulations. The undulations define outer peaks and inner valleys. The first end preferably includes a curved surface which curves back from the plane of the driver. The second end of the enclosure is preferably provided with a port, but may also be provided with another driver directed outward. The enclosure is preferably molded from fiberglass reinforced polyester. According to a preferred embodiment of the invention, the speaker enclosure is substantially frustoconical in shape. The port may be provided with a flexible tube or a flexible tubular segment may be provided on the enclosure at the second end, or at some location between the first and second ends. With each embodiment several acoustic advantages are realized. The undulating wall of the speaker system randomizes the internal sound waves, thereby substantially preventing the creation of standing waves and providing a very stable non-flexing enclosure such that associated distortion is eliminated. |
