Unheard of reference subwoofer performance for the price and also for its compact size differentiate the SB-3000 subwoofer from anything available. The Sledge STA-800D2 DSP amplifier, innovative new 13-inch high-excursion SVS driver and an optimized sealed cabinet design take control of a room with deeper bass and higher output levels than what is typically possible from a relatively compact subwoofer. An ideal solution for reference bass in audiophile music systems or home theaters, the SB-3000 sets all performance benchmarks at its price and leaves larger and more expensive subs trembling in its wake.
