Abstract
A loudspeaker system has a high frequency channel for driving a horn loaded high frequency transducer, and a low frequency channel for driving a low frequency transducer. A signal processing circuit is provided which has at least one first order and at least one second order cross-over circuit portion in the high channel and at least one first order and at least one second order cross-over circuit portion in the low frequency channel. These cross-over portions produce a cross-over frequency range for the loudspeaker system that is below the cut-off frequency of the horn. The signal processing circuit, including its cross-over circuit portions and in conjunction with the design of the expansion walls of the horn, extends vertical beamwidth control of the acoustic output of the loudspeaker system at the loudspeaker system's lower frequency range.
