A sealed 13-inch subwoofer with an 800-watt RMS Sledge amplifier, Bluetooth app control and response down to 18Hz. The SVS SB-3000 fits it into a cabinet about 40cm high and 39cm wide.
It has a Bluetooth app with presets and a three-band parametric EQ, plus rear-panel controls for volume, low pass and phase. SVS says it takes technology from its 16-Ultra and 4000 Series subwoofers.

Why you will love it
13-inch high-excursion driver
SVS describes an all-new 13-inch driver with an aluminium vented cone, a composite fibre dustcap and a long-throw parabolic surround. The dual ferrite magnet motor weighs nearly 25lb (about 11kg).
The flat edge wound split-wind voice coil sits on a 2-inch fibreglass former, and the basket is cast aluminium.

Sledge STA-800D2 amplifier
The Class D amplifier is rated at 800 watts RMS and 2,500+ watts peak, using fully discrete MOSFETs. A 50MHz Analog Devices DSP with 56-bit filtering handles tuning and room correction.
App and rear-panel control
The SVS app connects over Bluetooth. It offers three saved presets, a three-band parametric EQ, low pass, phase, polarity and room gain compensation, with changes shown on both the app and the rear panel.
The rear-panel interface has backlit controls for volume, low pass and phase, an RCA stereo input and output, and a 3–12V AC/DC trigger input.


Braced sealed cabinet
SVS uses a double-thick MDF front baffle, extensive internal bracing and acoustic insulation to keep the cabinet from colouring the sound. A steel mesh grille and elastomer feet are included.
Is it right for you?
A great fit if you…
- Want deep, controlled bass for movies and music
- Like tuning with an app and saved presets
- Have room for a cabinet about 40cm square
- Might add a second sub later
Worth knowing
- It uses a line-level RCA input, so you need a subwoofer or pre-out on your receiver or amplifier
- Sealed cabinets suit tight, controlled bass. The ported PB-3000 goes lower but is a much larger cabinet
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-3000 ported subwoofer is the ported 3000 Series model
- Go dual: Add a second SB-3000 for smoother bass across the room

How do I connect it?
Use the RCA input from a subwoofer output or pre-out. A 3–12V trigger input can switch it on with your system.
How deep does it go?
SVS rates the frequency response at 18 – 270Hz ±3dB, measured on a 2-metre ground plane.
Should I get two?
SVS recommends multiple subwoofers where possible for smoother bass at more seats.
