ABSTRACT:
A dual loudspeaker is set up to handle separately high frequency and low frequency sounds in the same piece of equipment. The apparatus comprises a single housing having a vertical partition dividing the housing into two chambers. A high-frequency driver in one chamber feeds into a relatively short horn path to a high frequency bell. A low-frequency driver in the other chamber feeds into a relatively longer horn path to a low-frequency bell. The high-frequency and low-frequency bells are located side by side on opposite sides of a partition and feed into a progressively expanding horn which serves simultaneously the output of both drivers.
