SVS - 13-1/2" 1200W Powered Subwoofer - Premium Black Ash

SVS PB-4000 - subwoofer

Key Features and Benefits: Sledge amplifier - massive output, sophisticated DSP, advanced power management The PB-4000 Sledge STA-1200D amplifier uses 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 powered subwoofer manufacturer. High current output of fully discrete MOSFETs with efficiency of Class D amplifier Efficiency of a Class D amplifier with the ability to move massive amounts of current through the fully discrete MOSFETs enabling immense output and precise control for outstanding real-world subwoofer performance at all drive levels. Sophisticated 50 MHz high resolution analog devices audio DSP The advanced digital processor maintains pinpoint accuracy and pristine sound quality through advanced in-room tuning, optimized frequency response curves, powerful DSP controls and more. Variable port tuning modes Foam port plugs come standard with the PB-4000 and allow for variable tuning. Each response curve for the three port tuning modes; standard, extended and sealed, is fully configured to the respective mode to achieve balanced and accurate low frequency response with all tuning preferences. Active Power Factor Correction (PFC) & ground loop isolation 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.
