The SB-900 subwoofer is the perfect companion for any Home Theater or compact music system, and it makes an ideal match for a soundbar, such as the Atlantic FS series. Small, unobtrusive and deceptively simple-looking, the SB-900 has a rugged 8” driver with an oversized surround for exceptionally long excursion and low distortion, even at very high output levels. Drivers of this capability are never found on subwoofers at this modest price. Its high-current, equalized 125-watt amplifier and massive finned heat sink give another indication that we put our efforts into the ‘guts’ and not into needless cosmetic frills. The SB-900 has a low-end extension of 32 Hz (-3 dB)—the lowest fundamental note in the musical spectrum—and its solid, muscular sound surprises and delights listeners every time.

Just because the SB-900 is Atlantic's least-expensive subwoofer doesn’t mean they skimped on its features or hookup flexibility. Like all Atlantic subs, the SB-900 has an adjustable crossover, a crossover bypass setting for use with electronics that have built-in bass management, auto-on signal sensing, phase control, and a detachable AC power cord, and special proprietary distortion-detection circuitry that prevents the SB-900 from emitting objectionably-distorted sound, regardless of how hard it’s pushed.
