About the SF 10C SUB
on the next page) is a plenum-rated, 8 ohm, 4th order
band-pass subwoofer with a tuned bass-reflex port. When installed, the subwoofer is
typically suspended by wire from the structural ceiling above the suspended ceiling. This
avoids unwanted rattling and vibrating in the ceiling tile grid. It features a 10-inch ported
woofer housed within a cylindrical enclosure. A right-angle port on the front of the enclosure
directs the sound waves into the listening area.
The subwoofer has a frequency range of 25 Hz to 160 Hz, -10 dB, half space.
The SF 10C SUB is compatible with any Extron low impedance amplifier with sufficient
output drive power. The unit is UL 2043 Listed for use in air-handling spaces.
The subwoofer is intended for use in a bi-amplified system. Separate amplifiers should
power the low and high frequencies.
