Short answer: the SVS SB-3000. It ranks #15 of 212 subwoofers by sound quality, rated 4.1/5, at $1,149; the XTZ Sound 99 W12S ranks #61, rated 3.8/5, and costs $1,499, which makes this an easy call rather than a real tradeoff.
What the SVS SB-3000 does well: A well made sealed subwoofer with tight, accurate bass and handy app controls, great for music and medium rooms. The tradeoff: 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.
What the XTZ Sound 99 W12S does well: A ported 12 inch subwoofer with a strong amplifier, phase control and EQ switches for tuning it to the room. Watch for: Deep output falls off sharply, with 86.5dB at 25Hz and 74.0dB at 20Hz, so it is weak for the lowest movie effects.
Buy the SVS SB-3000. It is rated higher for sound quality than the XTZ Sound 99 W12S and costs less, which makes it the one to get unless you need something the other one does better.
