Abstract
This invention provides a speaker enclosure that minimizes or defuses standing waves and minimizes resonance within the operating frequency range of its transducers. To minimize standing waves, the speaker enclosure has no two surfaces that are parallel to each other thus preventing the propagation of standing waves. The interior surface of the speaker enclosure may have ribs spaced apart on any surface that is prone to resonate so that the surface is strengthened such that it resonates at a predetermined frequency that is typically outside of the operating frequency range of the transducers.
