Short answer: the Rythmik LV12. It ranks #8 of 212 subwoofers by sound quality, rated 4.2/5, at $899; the SVS SB-3000 ranks #15, rated 4.1/5, and costs $1,149, so there is little reason to consider the other one.
Why pick the SVS SB-3000: A well made sealed subwoofer with tight, accurate bass and handy app controls, great for music and medium rooms. The catch: Being sealed, it gives up deep-bass output: Audioholics measured 96.6dB at 20Hz and 101.7dB at 25Hz, about 15dB behind the ported SVS PB-3000 from the same series, so a large room or reference-level movie bass may call for a second sub.
Why pick the Rythmik LV12: A great value 12 inch servo controlled subwoofer with deep bass and switchable tuning for depth or loudness. Watch for: At 495 by 381 by 470mm and 69 lbs (31.3 kg) it is a large, heavy cabinet for a 12 inch subwoofer.
Buy the Rythmik LV12. It is rated higher for sound quality than the SVS SB-3000 and costs less, so only choose the other one for a particular feature it does better.
