Short answer: the Monoprice SW-15. It ranks #14 of 212 subwoofers by sound quality, rated 4.1/5, at $499.99; the JL Audio E112 ranks #34, rated 3.9/5, and costs $2,500, so there is little reason to consider the other one.
Why pick the Monoprice SW-15: A big 15 inch subwoofer with powerful, punchy bass at a budget price, great for movies in a large room. Watch for: Budget-tier design, ported room gain dependency, 66.1 lbs (30 kg) mid-size, and limited dynamic headroom.
Why pick the JL Audio E112: A sealed 12 inch subwoofer with fast, powerful bass, a very strong amplifier and excellent build quality. The tradeoff: There are no balanced inputs and no built-in EQ, which a SVS SB13-Ultra with similar output includes for $400 to $500 less.
Buy the Monoprice SW-15. It is rated higher for sound quality than the JL Audio E112 and costs less, so only choose the other one for a particular feature it does better.
