The SB-2 is a biamplified sound reinforcement loudspeaker housed in
a parabolic dish enclosure. Capable of high sound pressure levels with
precisely defined narrow coverage, the SB-2 offers a unique solution
for large-scale distributed paging and music systems.
While distributed loudspeakers are often employed in an attempt to
overcome reverberation and improve intelligibility, large venues pose
problems of scale that conventional loudspeakers designs cannot address.
The SB-2 provides an effective solution to these problems. Featuring
a tight 20-degree coverage pattern with high output capability, the
SB-2 offers the ability to cover individual zones with highly intelligible,
full-range sound while avoiding overlapping. A hybrid, two-way system,
the SB-2 uses a waveguide to achieve directionality at high frequencies
and a parabolic array of cone drivers at mid-to-low frequencies.
Because the SB-2 achieves very tight directional control in the critical
mid frequencies, it enables designers of distributed systems to circumvent
the usual tradeoffs between even sound pressure levels and minimized
combing. Its tight directional control also minimizes reverberation,
maximizing intelligibility. And with its high peak SPL output, the SB-2
can throw over much longer distances than conventional loudspeakers.
The SB-2 comprises 28 4-inch cone drivers, a 2-inch throat (4-inch
diaphragm) compression driver, an integral complementary MOSFET power
amplifier with 1240 watts burst capability, optimized signal processing
circuitry, and compatibility with RMS remote monitoring system.
