SVS SB17-Ultra R-Evolution 17" 2800W Sealed Powered Subwoofer

The SVS SB17-Ultra R-Evolution stands at the absolute zenith of sealed subwoofer engineering, establishing a new benchmark for subterranean depth, transient precision, and unyielding acoustic output. Engineered around an all-new 17-inch high-excursion driver with a composite glass-fiber laminate cone, this reference active subwoofer harnesses an unprecedented dual 8-inch voice coil architecture driven by a massive 55-pound toroidal ferrite motor assembly. The sealed acoustic suspension enclosure delivers immaculate acoustic timing, instantaneous transient impulse response, and deep room energization reaching down to an astonishing 15 Hz (+/- 3 dB) without port coloration or air turbulence.

Powering this monumental acoustic system is the groundbreaking Sledge STA-2800D dual-mono Class D amplifier, combining discrete MOSFET output stages to deliver 2800 watts RMS of continuous power and over 6000 watts of dynamic peak power with vanishingly low distortion. Sophisticated onboard signal processing is governed by a 295 MHz 56-bit Analog Devices audio DSP running proprietary algorithms, paired with high-precision 120 dB SNR DACs. Complete acoustic control is managed effortlessly via the SVS smartphone app, offering wireless Bluetooth access to parametric EQ, volume, phase, low-pass filters, and advanced Auto EQ room calibration using your device microphone to optimize in-room boundary interaction across luxury home cinemas and audiophile stereo systems.
