SVS 1000 Pro Series Subwoofers: MOSFET Amplifier and Analog Devices Processor in Two Cases

The series of 1000 Pro subwoofers from the American company SVS, which replaced the usual thousandth, has so far included only two models: SB-1000 and PB-1000. The first is in a bass reflex (two ports), the second is in a closed case. Otherwise, they are practically twins.

The 12-inch long-throw driver of the new series received a fiber composite cone with a parabolic suspension. The driver is equipped with a double ferrite magnet and a double layer voice coil.

Both 1000 Pro models are equipped with a Sledge STA-325D amplifier. It combines the high output current of discrete MOSFETs with Class D energy efficiency. Its 325W RMS power can reach 820W peak or slightly.

The signal for the amplifier is processed by an Analog Devices 50 MHz, 56-bit filtered audio processor, which SVS has described in a press release as “the most advanced DSP available in a home subwoofer”.

New items are configured from the application for mobile devices via Bluetooth, and this system is borrowed from the monstrous 16-Ultra model.

The SB-1000 and PB-1000 housings have additional high-strength plastic inserts and anresonant elastomer feet. Both subwoofers can be covered with a solid cloth grill.

On the SVS website, the SB-1000 Pro subwoofer starts at $500, and the PB-1000 Pro starts at $600.
