Serious Bass, Tight and Deep The SVS SB-3000 is a sealed subwoofer for people who want serious output without giving up control. A 13-inch driver and 800-watt Sledge amplifier deliver deep, powerful bass down to 18Hz, yet the sealed cabinet keeps it tight and accurate, so movies hit hard and music stays tuneful. Full app tuning lets you dial it in precisely to your room. Why You'll Love It Deep, powerful, controlled: The big 13-inch driver and 800 watts reach down to 18Hz with the impact of a much larger sub, while the sealed design keeps every note tight and accurate rather than boomy. Fills bigger rooms: With far more output and extension than the compact 1000-series subs, the SB-3000 has the muscle to pressurise a large lounge or home theatre and still sound effortless. Tune it from your seat: The SVS app puts crossover, parametric EQ, polarity, room gain and custom presets on your phone, plus a touch interface on the sub itself, so dialling it in takes minutes. Under the Hood 13-inch high-excursion driver: A large SVS driver with dual toroidal magnets moves huge amounts of air with precision and control, for clean output even at reference levels. Sledge STA-800D2 amplifier: 800 watts RMS (2,500W peak) of Class D power with a high-resolution DSP keeps the driver under tight control at any volume. Sealed for accuracy: The rigid sealed cabinet is tuned for a natural 18Hz to 270Hz response, favouring tight, true-to-source bass over the exaggerated output of a ported design. CHT Insider Verdict The SB-3000 is where SVS's sealed range gets serious. It's the sub to choose when a compact 1000-series model runs out of steam in a bigger room but you still want the tight, musical sound of a sealed design. It's a real step up in output and depth, and one of the best sealed subs at the price. Need to fill a very large space or want maximum home-theatre slam? Look at a ported SVS or a larger sealed model. Pro Tip: Sealed subs like the SB-3000 roll off gently, so in a real room the bass usually plays lower than the 18Hz spec suggests. Placing it in or near a corner boosts that deep output for free, then use the app's room-gain control to keep it from getting boomy.
