Abstract: An audio driver assembly which equalizes the atmospheric pressure in a sealed enclosure and is capable of canceling external sounds in a non-sealed enclosure, resulting in the improvement of the reproduction of sound quality through a dual cone audio speaker.

Abstract: The present invention is a small high fidelity full spectrum speaker, which arranges a passive speaker and two active speakers such that fidelity of a larger speaker or one with a cross-over network is achieved.

Abstract: A loudspeaker system designed to minimize the enclosure to fit in furniture and exceed high end fidelity sound found in larger and more complex systems. The system presented herein incorporates a sealed enclosure utilizing two small diameter audio drivers, 3? or larger depending on application, and a passive radiator, ported into a bass chamber with a tuned port. The two drivers are wired 180 degrees out of phase, aligned on the central axis, but facing opposite directions, resulting in a push-pull alignment. With the sealing of the enclosure, the internal driver becomes a static engine that projects the image of the sound stage while reducing the mechanical excursion, allowing higher SPL levels and more accurate reproduction of all frequencies in a small enclosure.
