The FAPSUB-1 adds impressive low frequency response to any full range distributed system
The FAPSUB-1 consists of a highly efficient 8", 8 ohm subwoofer designed and built by Atlas Sound to work optimality in the FAPSUB-1 enclosure system. A highly efficient, 3-pole filtering network eliminates unwanted high frequencies from the woofer,while the 937 cubic inch, tuned and ported, deep drawn steel enclosure provides bass response down to 45Hz (±10dB).
A special low saturation 70.7V/100V transformer is included with 1.9, 3.8, 7.5, 15, 30 and 60 watt primary taps (@70.7V) 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.
