The original Aria 7 Tower as designed
by Joe D'Appolito. Since I needed to have the Aria7s sit upon subwoofers, I made the front as small as practicable (to minimize edge diffraction) and increased the depth of the cabinet to retain the same net interior volume. So I made Aria 7s with an entirely different shape, but retained Mr. D'Appolito's design. |
