The SB-900DF features an 8″ long-excursion woofer with an oversized surround and high-energy magnet. Combined with its tuned bass port and 125-watt power amplifier, it delivers high output levels and exceptional low-frequency extension down to 32Hz, -3dB – the lowest fundamental note in the musical spectrum. Proprietary distortion-detection circuitry ensures it doesn’t output distorted sound no matter how hard it is pushed. Fine tuning controls help improve the subwoofer’s sound, and an auto-on sensor helps you save power by automatically turning it off when not in use.
The Atlantic Technology SB-900DF has a peak output of 102 dB SPL in a 2000 cubic foot room and a frequency response for 32 to 200 Hz, ±3 dB. The black-finished cabinet measures 10-7/8 wide, 13-1/8 high, and 13-1/16 deep, and weighs 28 lbs. It is available now from Atlantic Technology dealers with a retail price of $349.
