Short answer: the SVS SB-3000. It ranks #15 of 212 subwoofers by sound quality, rated 4.1/5, at $1,149; the MartinLogan Dynamo 12 ranks #149, rated 3.5/5, and costs $1,279.99, which makes this an easy call rather than a real tradeoff.
The SVS SB-3000 is the better-sounding pick. A well made sealed subwoofer with tight, accurate bass and handy app controls, great for music and medium rooms. Watch for: 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 MartinLogan Dynamo 12 does well: A sealed 12 inch subwoofer with app control and built in room correction that simplifies setup in a mid size room. Watch for: Nearly all controls, including low-pass frequency and phase, are app-only, with no physical switches for systems that lack separate bass management.
Buy the SVS SB-3000. It is rated higher for sound quality than the MartinLogan Dynamo 12 and costs less, which makes it the one to get unless you need something the other one does better.
