Abstract
A coaxial speaker system that includes an acoustic bass resonator, a lower speaker case that extends from the acoustic bass resonator, an upper speaker case that extends from the lower speaker case, and a coaxial speaker that interfaces with both the lower and upper speakers cases. The acoustic bass resonator and the lower and upper speaker cases are each tubular. The acoustic bass resonator has a pair of ports that extend therethrough. The lower speaker case has a pair of bass ports that extend through diametrically opposite sides thereof, a first diffuser panel that extends coaxially therein, and a second diffuser panel that extends coaxially therein, perpendicular to the first diffuser panel. The upper speaker case has a port that extends therethrough and is generally parabolic-shaped, and a high frequency deflector panel that is generally parabolic-shaped, extends skewly rearwardly therein, and cooperates with the port therein.
