TOA SPEAKER SYSTEM
CEILING MOUNT 3-WAY SPEAKER
SF-30
DESCRIPTION
The TOA SF-30 is a 3-way loudspeaker system designed to
be suspended from the ceiling. Its bass-reflex enclosure
houses a heavy-duty 12-inch woofer, a constant directivity
horn coupled with a high-efficiency compression driver, and
an exponential horn tweeter. The constant directivity horn
ensures a uniform dispersion pattern of 90° horizontal and
40° vertical.
A high-tech crossover network of – 18 dB/octave slope is
used between the woofer and the driver. This combination
produces an extended, smooth frequency response and
wide coverage area. The system will handle 120W RMS of
continuous pink noise and 360W of continuous program
material.
The rear panel has 1/4” phone jacks and screw-type termi-
nals for full-range operation. The phone jacks can be con-
verted into XLR connectors. Mid and high frequency level
controls are provided on the side of the speaker enclosure.
T-nuts for ceiling suspension mount brackets are provided
on the rear slant and on both sides of the enclosure. The
enclosure is finished in gray polyester. The black punched
metal front grille is removable.
