Different price classes - SVS 3000 In wall Dual Subwoofer System costs roughly 5x what SVS SB-1000 Pro does. Before paying it, read the note below about two smaller subwoofers.
| Area | Better | Why |
|---|
| Bass depth | evenly matched | Effectively the same reach (22Hz vs 20Hz). |
| Amplifier power | A | SVS 3000 In wall Dual Subwoofer System has the bigger amplifier - 800W against 325W RMS, about 3.9dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | evenly matched | Near-identical radiating area (2 x 9" against 12"). |
| Enclosure | evenly matched | Both are sealed designs, so they roll off in much the same way. |
| Cabinet size | depends | SVS 3000 In wall Dual Subwoofer System is about 60% smaller by volume. In a subwoofer that is a real trade rather than a preference: box volume is how you get output low down without a bigger amplifier. |
| Price | B | SVS SB-1000 Pro costs less - $600 against $3,000, about 80% less. |
A SVS 3000 In wall Dual Subwoofer System B SVS SB-1000 Pro
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both subwoofers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
SVS 3000 In wall Dual Subwoofer System is ahead, but on only 1 of the measured areas, and it costs about 5x the price. SVS SB-1000 Pro is the sensible buy unless your room is large enough to need the extra. Two small subwoofers beat one big one in most rooms - a pair evens out the room modes in a way no single box can, whatever its specs. At $600 each, two SVS SB-1000 Pro cost about $1,200 against $3,000 for one of the other, which is worth a thought. If placement is the constraint - a corner, behind a sofa, under a desk - SVS 3000 In wall Dual Subwoofer System is the one that will actually go there, and a well-placed small subwoofer beats a badly-placed big one every time.
One thing outweighs everything above: where the subwoofer stands. Room modes can add or remove 10dB or more at a given seat, which is far larger than any difference on this page. Before spending more, try the sub in two or three positions - the crawl test, where you put it in the listening seat and crawl the room to find where the bass sounds best, costs nothing and usually beats an upgrade.
