The SB17-Ultra R|Evolution is SVS's hardest-hitting sealed subwoofer — the most potent and sophisticated the company has ever built. A massive 17" driver with dual 8-ohm voice coils, each powered by its own dedicated monoblock amplifier, delivers reference-level output with surgical control.
The sealed cabinet keeps the low end tight and room-friendly despite the sub's scale, extending useable bass down to 13Hz.
A front-panel Intelligent Control Interface with touch buttons and an LED bar handles day-to-day adjustments, while the free SVS smartphone app unlocks full control: 6-band parametric EQ, variable low-pass crossover, phase control, and automatic Room EQ that measures your room with a smartphone microphone and corrects the response for you. Three presets — Movie, Music, and Custom — let you switch tunings instantly from the couch.
Both unbalanced RCA and balanced XLR line-level/LFE inputs are on board, along with RCA and XLR outputs so you can daisy-chain a second subwoofer for even bass coverage across a larger room.
SVS was founded in 1998 by a group of audio enthusiasts seeking a better alternative to the under-performing, over-priced subwoofers of the time. By applying rigorous engineering and using premium components, SVS has built a line of high-performance, high-value audio products that bring music and movies to life with startling realism.
