ABSTRACT:
The present invention discloses a ported reflex speaker enclosure for use in the automotive audio systems industry. The ported reflex speaker enclosure is a design that factors the audio and thermal design considerations as found in the automotive operating environment as well as factoring the audio and mechanical mounting considerations as found in the automobile audio systems. The ported reflex speaker enclosure is primarily intended for six (6) by nine (9) inch standard speaker chassis used in automotive audio systems that typically are found as non-enclosed suspended speakers in the trunk compartment of automobiles. The speaker enclosure is a concave body having an oval shaped rim portion for receiving a similarly shaped speaker device, a convex bottom, a first sound fidelity enhancement reflex port for directing sound waves to a listening compartment, a second sound fidelity enhancement in the form of an exhaust hole for controlling sound wave pressure emanated from an enclosed speaker located within the concave body and a third sound fidelity enhancement in the form of equalizing notches that complement the exhaust hole's control of sound wave pressure emanated from an enclosed speaker.
