Short answer: the Monoprice SW-15. It ranks #14 of 212 subwoofers by sound quality, rated 4.1/5, at $499.99; the ELAC SUB3010 ranks #141, rated 3.6/5, at $499. With prices this close, go by the sound-quality ranking rather than the cost.
The Monoprice SW-15 is the better-sounding choice. A big 15 inch subwoofer with powerful, punchy bass at a budget price, great for movies in a large room. The catch: Budget-tier design, ported room gain dependency, 66.1 lbs (30 kg) mid-size, and limited dynamic headroom.
What the ELAC SUB3010 does well: A 10 inch subwoofer with a passive radiator and app based automatic room EQ using your phone’s microphone. Watch for: Output falls to 97.9dB at 25Hz and 83.8dB at 20Hz, so it will not shake the room with the lowest bass.
Buy the Monoprice SW-15. It is rated higher for sound quality, and the $0.99 saving on the ELAC SUB3010 is not enough to make up the difference.
