ABSTRACT:
An asymmetrically resonance speaker enclosure is disclosed. Each side of the speaker box is reinforced asymmetrically, ensuring that each side has different resonance characteristics. Thus, the peak in the speaker box resonance is spread out, thereby reducing the effect of box resonance on the sound and making the box resonance more susceptible to being masked by tonal adjustments in the system. In addition, the material used to construct the box has fast energy dissipation and no heavy internal cross bracing is used. These features reduce the smearing effect of the speaker box on sound produced by the speakers. Thus, a system using an asymmetrically tuned speaker enclosure will sound less "boxy," will have less compression in the sound stage, will reveal more detail to the listener and sound livelier.
