SVS SB-4000 13.5" 1200W Sealed Box Subwoofer (Premium Black Ash)

Chest-thumping slam and extreme low frequency extension with pinpoint accuracy and refined musicality a level of subwoofer performance not seen at this price before. The SB-4000s 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. A top choice for 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.

Rated conservatively at 1200 watts RMS and 4000+ watts peak power the 4000 Series Sledge STA-1200D amplifiers use an efficient Class D design combined with fully discrete MOSFET output and a sophisticated Analog Devices DSP engine. The result is a level of effortless power and advanced processing not available from any other subwoofer manufacturer.

Combines the efficiency of a Class D amplifier design with the ability to move massive amounts of current through the fully discrete MOSFETs enabling immense low frequency output and precise driver control. Put simply outstanding real-world subwoofer performance at all drive levels.

Most advanced digital processor ever used in a subwoofer maintains pinpoint accuracy and pristine sound quality through advanced in-room tuning optimized frequency response curves powerful DSP controls and more.

Maximizes the subwoofers ability to take control of a room and benefit from the acoustic potential of the space it occupies by tailoring the roll off slope. The effect is accurate frequency response with staggeringly deep in-room extension often as low as 10Hz - without the boominess commonly associated with room gain.

Allows the amplifier to deliver all the way to the limits of its rated power and maximize on the drivers potential with massive output and no distortion.

Serves as a line conditioner surge suppressor and voltage regulator letting the amplifier deal with wide voltage fluctuations and ensuring the subwoofers operate flawlessly on any household circuit no matter how unstable the incoming current.

An isolated circuit creates a vanishingly low noise floor by eliminating the potential for ground loop hums from outside components resulting in absolute sonic transparency.

SVS 4000 Series drivers handle every watt of the Sledge STA-1200D amplifiers power with precision and control to produce room energizing SPLs and effortless low frequency extension with pinpoint accuracy at all drive levels.
