The driver uses a lightweight and rigid aluminium vented cone with a composite fibre dustcap, which is combined with a proprietary injection moulded gasket and long-throw parabolic surround to allow for extreme excursion and incredibly deep bass. There’s a dual ferrite magnet motor assembly weighing over 11kg, along with a flat edge wound split-wind voice coil within the motor assembly. Together, they deliver sufficient power at the highest excursion levels, but reduce mass and improve overall driver efficiency.
The driver’s ability to move massive amounts of air is backed up by a rear-mounted Sledge STA-800D2 amplifier, combining the high current output of discrete MOSFETs with Class D efficiency to deliver a claimed 800W RMS and peaks of up to 2,500W. All this is governed by a 50MHz Analog Devices DSP with 56-bit filtering that SVS claim is the most advanced digital processor ever used in a subwoofer.”
