AIR Dual 8" In-Ground Subwoofer

The AIR IGS82T is a passive in-ground subwoofer, employing dual 8” woofers for tight,
controlled bass. Power handling is 200 Watts (program) at 8 Ohms, with a frequency
response of 38 Hz to 150 Hz (±3 dB) and usable low-end range down to 25 Hz. Its built-
in 150 Hz low-pass filter allows the AIR IGS82T to be driven by a full range power amplifier
without requiring a separate external crossover.

Using its internal transformer, the AIR IGS82T may be operated at 70 or 100 Volts, allowing
multiple subwoofers to be connected in parallel and driven by a single high-powered 70 or 100
Volt power amplifier. Running at 70 or 100 Volts allows for longer wire runs using lower gauge
wire than is required by an 8 Ohm speaker.

The AIR IGS82T includes a short length of direct-burial wire that is permanently attached to the
speaker enclosure. A suitable in-ground electrical box (not included) is advised for termination of
the speaker and transformer wiring. A set of five waterproof wire nuts is included.
