Product Description

Unparalleled Low Frequency Depth Power and Detail 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-4000’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. 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. 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. High Current Output of Discrete MOSFETs with Efficiency of Class D Amplifier 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. Sophisticated 50Mhz High Resolution Analog Devices Audio DSP 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. Room Gain Maximizes the subwoofer’s 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. Advanced Limiting Allows the amplifier to deliver all the way to the limits of it
