New SVS 17-Ultra Revolution Subwoofers are about to land. Engineered from the ground up, the new sealed SB17-Ultra and ported PB17-Ultra subwoofers feature advancements to driver, amplifier, power supply and DSP technology including new auto EQ room correction.
Mirroring the size of their 16-Ultra predecessors, the new subwoofers feature a new 17-inch dual voice-coil SVS driver, dual mono-block Class-D amplification, uprated power supply and advanced DSP and app control. Consequently, the sealed box SB17-Ultra and ported PB17-Ultra designs are the most powerful, sophisticated, and user-friendly SVS subwoofers ever introduced to the consumer market.
New drivers
As the most formidable driver ever deployed in an SVS subwoofer, the all new high-excursion 17-inch design features a 25kg toroidal ferrite magnet motor using SVS’ first dual eight-inch, copper-clad aluminium voice coil to deliver effortless output and exacting control.
New amplifiers
Sonic muscle is provided by a new dual mono-block STA-2800D Class-D amplifier with MOSFET output stage. Each amplifier drives one of the dual voice coils to increase the power into the motor. Eight 60A/200V MOSFETs deliver the high current necessary for reference-level output with maximum efficiency.
More sophisticated DSP and app control
An advanced, high-resolution 295MHz Analog Devices DSP orchestrates every function of the amplifier while the most comprehensive subwoofer control smartphone app available (iOS, Android, and Amazon Fire) manages calibration and setup. New to the 17-Ultra Revolution subwoofers is intuitive auto EQ subwoofer room correction, which uses the SVS app and the built-in microphone on a user’s smartphone to apply equalisation filters automatically for optimal room gain and in-room frequency response.
