Get the Details
Designed for speed and authority, the massive 17-inch driver moves serious air while maintaining the quick start/stop behavior sealed subs are known for—ideal for detailed musical bass and tight, punchy cinematic slam.
The dual-mono STA-2800D amplifier provides huge continuous power and peak dynamic headroom, helping the SB17-Ultra R|Evolution stay composed at reference levels with low distortion and strong control.
15Hz–320Hz (+/-3dB) frequency response
From infrasonic rumble to a seamless crossover region, the SB17-Ultra R|Evolution covers the full bandwidth needed for modern LFE tracks and clean integration with speakers in both home theater and stereo systems.
295MHz DSP with app control, PEQ, presets, and advanced tuning
Use the SVS app to fine-tune bass for your room and taste with phase, polarity, low pass control, room gain compensation, and six parametric EQ bands, plus multiple presets for instant switching between listening modes.
RCA + balanced XLR stereo input/output with trigger, IR, and USB power
Flexible connectivity supports everything from standard AVR LFE hookups to balanced pro-style runs, while trigger/IR ports help integrate into custom systems and USB can power an optional wireless adapter.
Premium braced MDF cabinet, ABS grille, and iso-elastomer feet
A rigid, internally braced enclosure reduces resonance and coloration, the thick ABS grille protects the driver without rattles, and the iso-elastomer feet improve stability while reducing unwanted mechanical noise.

SVS SB17-Ultra R|Evolution Subwoofer
The SVS SB17-Ultra R|Evolution Subwoofer is a reference-grade sealed subwoofer engineered for chest-thumping movie impact and fast, textured musical bass—without boom or overhang. At its core is a massive front-firing 17-inch high-excursion driver with a groundbreaking dual 8-inch voice coil motor system, powered by the formidable Sledge STA-2800D amplifier delivering 2,800W RMS (6,000+W peak). The result is deep, pressurizing low-end with the speed and control sealed subwoofers are known for, reaching a stunning 15Hz to 320Hz (+/-3dB).
Dial in bass exactly for your room and system using the SVS Subwoofer Control App (iOS/Android/Amazon Fire) with advanced DSP tools—including six parametric EQ bands, phase, polarity, low-pass control, and presets—plus Auto EQ room correction (available via over-the-air app update soon). With both RCA and balanced XLR stereo I/O, flexible power management, trigger/IR integration, and an OLED rear-panel interface, the SB17-Ultra R|Evolution is built to anchor elite home theaters and uncompromising two-channel setups alike. The SVS SB17 Ultra R is part of ListenUp's SVS Sealed Subwoofers Collection.

SVS SB17-Ultra R Q&A:
Will the SB17-Ultra R|Evolution work well for both movies and music?
Yes. Its sealed design and powerful DSP deliver fast, controlled bass for music while still producing room-pressurizing impact for movie soundtracks down to 15Hz.
How deep does this subwoofer play?
The rated frequency response is 15Hz to 320Hz (+/-3dB), delivering ultra-deep low-frequency extension well into infrasonic territory.
What connections does it support—RCA, XLR, or both?
It supports both RCA and balanced XLR, including stereo input/output so it can integrate into consumer home theaters and higher-voltage/pro audio-style setups.
Can I control it from my phone?
Yes. The SVS Subwoofer Control App (iOS/Android/Amazon Fire) lets you adjust volume, low pass, phase, polarity, room gain compensation, tuning modes, power settings, and six parametric EQ bands, plus presets.
Is Auto EQ room correction included?
Auto EQ room correction is designed for the platform and is noted as available via an over-the-air app update soon, allowing guided in-room measurement and EQ filter creation.
Does it support a 12V trigger and IR control systems?
Yes. It includes a 3.5mm trigger input (3–12V AC/DC) and a 3.5mm IR input for easier integration with control systems.
How big and heavy is it?
With the grille installed it measures 20.0” H x 19.5” W x 21.2” D and weighs 124.0 lbs unboxed (136.0 lbs shipped), so plan for a sturdy placement and a careful unboxing.
Can I run dual SB17-Ultra R|Evolution subwoofers or daisy-chain multiple subs?
Yes. Using the RCA/XLR outputs, you can pass signal to additional subs for dual (or more) subwoofer setups, helping smooth bass response across more seats.
