The TOA SF-30 is a 3-way loudspeaker system capable of
being suspended from the ceiling. The system consists of
bass-reflex enclosure housing a hevy-duty 12-inch woofer,
bass-reflex enclosure housing a hevy-duty 12-inch woofer,
a constant directivity horn coupled with high-efficiency
compression driver, and an exponential horn tweeter. The
constant directivity horn ensures a uniform dispersion pat-
compression driver, and an exponential horn tweeter. The
constant directivity horn ensures a uniform dispersion pat-
tern of 90 degrees horizontal and 40 degress vertical.
A high-tech crossover network of –18dB/octave slope is
A high-tech crossover network of –18dB/octave slope is
used for crossover between the woofer and the driver.
This combination results in an extended smooth frequency
response and wide coverage area. The system will handle
120 watts RMS of continuous pink noise and 360 watts of
