ABSTRACT:
A speaker housing arrangement which uniquely combines a number of acoustic functions is disclosed in both a simple embodiment and in a more complex embodiment. Each embodiment utilizes a pair of angular deflectors in a tubular or pipe type enclosure to directionally co-align the sound product from both sides of the speaker cone. A slight interval in time of egress between the pressure opposite signals provides sonic contrast and hence sharp imaging. In the simpler embodiment linearity and signal integrity is preserved throughout the sound spectrum. In the more complex embodiment part of the bass signal is momentarily retained for purposes of co-phasing in a partial bass reflex arrangement. Either embodiment permits the production of sound of unusual quality and quantity in relation to input energy and to cost and grade of components. Secondary improvements in high frequency linearity and in overall spectral equalization in the region of the speaker itself are also disclosed.
