From Atlas Sound, the 8" Tuned Ported In-Ceiling Subwoofer adds low-frequency response to any full-range distributed system. A highly efficient, 3-pole filtering network eliminates unwanted high frequencies from the woofer and provides bass response down to 45 Hz (±10 dB). A special low-saturation 70.7/100V transformer is included to match and balance the subwoofer with full-range speakers without the need for separate amplification. A convenient front-mounted selector switch allows tap selection without the need to remove the speaker from the ceiling. This tap-selector switch also includes a transformer bypass setting for 8-ohm direct coupled applications
