A compact sealed subwoofer with a 12-inch driver, a 325-watt RMS Sledge amplifier and response down to 20Hz. The SVS SB-1000 Pro measures about 34 × 33 × 37.5cm and has Bluetooth app control.
It has both line-level RCA and speaker-level inputs, so it works with an AV receiver or a stereo amplifier.
SVS 1000 Pro Series overview
Why you will love it
12-inch long-throw driver
SVS describes an all-new 12-inch driver with a fibre composite cone, a dual ferrite magnet motor and a 1.5-inch voice coil with copper windings. It is rated at 13.3mm Xmax and 26.9mm Xmech.

Sledge STA-325D amplifier
The Class D amplifier is rated at 325 watts RMS and 820+ watts peak, with fully discrete MOSFETs and a 50MHz Analog Devices DSP with 56-bit filtering. EQ and limiter settings are set specifically for the 1000 Pro.
App control and connections
The SVS app connects over Bluetooth for iOS, Android and Amazon devices. It has three saved presets, a three-band parametric EQ per preset, low pass, phase, polarity and room gain compensation.
The rear panel has unbalanced RCA input and output, stereo speaker-level inputs and a 3–12V AC/DC trigger. A USB port can power the optional SVS SoundPath Wireless Audio Adapter.


Compact, braced cabinet
The sealed cabinet has an extra-thick MDF front baffle, internal bracing and acoustic absorption. An extra-thick ABS grille frame with fabric mesh cover and screw-in iso-elastomer feet are included.
Is it right for you?
A great fit if you…
- Want deeper bass for movies and music
- Need a sub that suits a living room
- Have a stereo amplifier without a subwoofer output
- Might add a second sub later
Worth knowing
- It has a 325W amplifier. The SB-2000 Pro has 550W for larger rooms or more output
- It uses a line-level RCA or speaker-level input, so it does not connect wirelessly without the optional SVS adapter
Build your system
SVS says: "At SVS, we're big fans of running multiple subwoofers whenever possible." SVS says two subwoofers give a smoother frequency response at more listening positions.
- Home theatre: Connect to an AV receiver's subwoofer output
- Stereo: Pair with a stereo amplifier and bookshelf speakers or floor-standing speakers
- Same range: SVS PB-1000 Pro is the ported 1000 Pro model, and SVS SB-2000 Pro is the larger sealed model
- Go dual: Add a second SB-1000 Pro for smoother bass across the room

Questions people ask
Can I use it with a stereo amplifier?
Yes. Use the RCA input if your amplifier has a pre-out or sub-out, or the speaker-level inputs if it does not.
Does it have an app?
Yes. The SVS app connects over Bluetooth with three presets and a three-band parametric EQ.
How deep does it go?
SVS rates it at 20 – 270Hz ±3dB, and says to expect 2–3Hz deeper extension in small to mid-size rooms.
Should I get two?
SVS recommends multiple subwoofers where possible for smoother bass at more seats.
