SVS PB-4000 13.5" 1200W Ported Box Subwoofer (Piano Gloss Black)

Jaw-Dropping Bass Extension and Output with Pinpoint Control and Accuracy Staggering levels of low-frequency output and subterranean deep bass extension down to 13Hz with an amazing degree of subtlety and finesse to thrill both action movie buffs and audiophiles. Sophisticated DSP technology in the PB-4000 creates three port tuning modes each with individual response curves to achieve the most accurate in-room frequency response possible. Its like having three subwoofers in one. Effortlessly powerful bass that extends far below the limits of human hearing the PB-4000 creates a physical experience with every listening session. 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 on 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. Port Tuning Each response curve for the three port tuning modes; standard extended and sealed is fully configured to the respective mode to achieve perfectly balanced and accurate low frequency response with all tuning preferences. Advanced Limiting Allows the amplifier to deliver all the way to the limits of its rated power and maximize on the drivers
