The SVS SB-1000 Pro is a sealed 12-inch powered subwoofer with a 325-watt amplifier, built for tight, accurate bass in a compact cabinet. It borrows control technology from SVS's 16-Ultra line, including app-based tuning and parametric EQ, which is rare at this level. Its sealed design favors speed and musicality over the deepest home-theater rumble of ported rivals like SVS's own PB-1000 Pro. Reviewers and owners praise its punch, build and app control, while some note it gives up low-end extension below roughly 20 Hz compared with ported boxes.

Owners and reviewers rate the SB-1000 Pro highly for its tight, punchy bass and compact size. Many call the app control and EQ a big step up from the original SB-1000. Some say it trades ultimate depth for accuracy compared with ported subs.
The SVS SB-1000 Pro is a 12-inch powered subwoofer with a sealed (acoustic suspension) cabinet. It is an upgrade to the SB-1000 and uses technology from SVS's 16-Ultra Series. The sealed enclosure keeps the cabinet compact.
The long-throw woofer has a fiber composite cone and is driven by a built-in 325-watt Class D amplifier with fully discrete MOSFETs. The cabinet's internal structure is reinforced to prevent resonance and coloration. The subwoofer reproduces low frequencies for movies, TV shows and games.
A 50 MHz DSP with 56-bit filtering controls the subwoofer at all drive levels. You can connect over Bluetooth and use a smartphone app to tune the sub to your room, adjust three-band parametric EQ and save custom presets. The rear panel has push-button controls for output level, room gain, low pass filter and phase, with an LED display bar.
