Chest-thumping slam and low frequency extension below the threshold of human hearing, with refined musicality – a level of subwoofer performance not seen at this price before. The SB-4000 subwoofer’s sophisticated DSP amplifier, innovative driver and a sealed box design master room gain and command a space with deeper bass and higher output levels than what is typically possible from a subwoofer of its size. An ideal option for reference quality bass in audiophile music or home theater systems, the SB-4000 sets all performance benchmarks for a subwoofer and leaves larger and more expensive subs trembling in its wake.
