Two quite different sizes of subwoofer. Room volume decides this more than anything else on the page: a big driver in a small room is wasted, and a small one in a large room is worked to death.
| Area | Better | Why |
|---|
| Bass depth | A | SVS 3000 In wall Dual Subwoofer System goes deeper - 22Hz against 27Hz. A real difference, though most music has little content below 27Hz. |
| Amplifier power | A | SVS 3000 In wall Dual Subwoofer System has the bigger amplifier - 800W against 200W RMS, about 6dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | SVS 3000 In wall Dual Subwoofer System moves more air: 2 x 9" against 10" is 1.62x the cone area, not the 1.27x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| 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 54% 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. |
| Warranty | A | SVS 3000 In wall Dual Subwoofer System carries 5 years on parts against 2 years. A subwoofer amplifier works harder than anything else in the system, so this is not a throwaway line. |
| Price | B | B&W ASW610 costs less - $899 against $3,000, about 70% less. |
A SVS 3000 In wall Dual Subwoofer System B B&W ASW610
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?
The usual trade-off: SVS 3000 In wall Dual Subwoofer System measures better, B&W ASW610 costs about 70% less. In a normal room, placement will make a bigger difference than the gap between these two. 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 $899 each, two B&W ASW610 cost about $1,798 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.
