SVS SB1000 Classic Sealed Subwoofer

Tight, Fast Bass in a Compact Box

The SVS SB-1000 Classic is a compact sealed subwoofer that punches far above its size. A 12-inch driver and 300-watt Sledge amplifier deliver deep, fast, accurate bass down to 24Hz from a cabinet small enough to tuck beside the sofa. Sealed rather than ported, it's built for the tight, musical low end that suits movies and serious listening alike.

Why You'll Love It

• Tight, accurate bass: The sealed cabinet gives fast, controlled low end that starts and stops on cue, so bass lines stay tuneful and effects hit hard without booming or overhang.

• Big output, small footprint: A 12-inch driver and 300 watts (720 watts peak) fill a room with deep bass down to 24Hz, from a box just 33cm wide and light enough to move with one hand.

• Fits any system: Line-level RCA and speaker-level inputs, plus variable crossover, volume and phase, integrate it cleanly with any amplifier or AV receiver, stereo or home theatre.

Under the Hood

• Sledge STA-300D amplifier: 300 watts RMS (720 watts peak) of Class D power with DSP tuning keeps the driver under precise control at any volume, a level of grip usually found in pricier subs.

• High-output 12-inch driver: An FEA-optimised motor, dual ferrite magnets and a vented pole piece give high output and low distortion while staying cool when pushed hard.

• Sealed for accuracy: The rigid, braced cabinet is tuned for a natural 24Hz to 260Hz response, favouring tight, true-to-source bass over the exaggerated output of a ported design.

CHT Insider Verdict

Sealed subs like the SB-1000 Classic trade a little outright output for speed and control, so they keep up with fast music and blend into a stereo system in a way ported subs struggle to. In most real rooms, room gain also carries the bass lower than the 24Hz spec suggests. It's the smart-money first sub: only look at a bigger ported design if you have a large room and mainly want home-theatre slam, and step up to the SB-1000 Pro if you want app control and EQ.

Pro Tip: If the budget stretches, buy two of these rather than one bigger sub. A pair of SB-1000 Classics placed around the room evens out the bass so every seat sounds right, not just the sweet spot, and two small subs almost always beat one big one. It's the single biggest bass improvement most rooms can make.
