The Behringer SAT 1008 SUBA 8" is an active installation Subwoofer that provides ultimate low-frequency reproduction of live sound or playback. It is powered by a 600-Watt Class-D amplifier with an 8" long-excursion subwoofer. While being compact and lightweight it produces an impressively rich and deep bass sound that will fill any room. With custom LF transducers the SAT 1008 produces extremely high sound pressure levels with a 110db max at 1m and a frequency range from 30 - 145 Hz. It has an ultra-rugged build too with built-in handles to make transport easy. While great paired with any passive full-range speaker thanks to its built-in stereo crossover the SAT 1008 works best with the specifically-designed SAT 1004 passive installation speaker.
