Short answer: the Monoprice SW-15. It ranks #14 of 212 subwoofers by sound quality (rated 4.1/5) at $499.99 and is still sold new; the Genelec 7050B ranks #210 (rated 2.7/5) and is discontinued, so it is only an option used. The Genelec 7050B’s replacement, the Genelec 7050C, is rated 2.7/5 at $1,575.
The Monoprice SW-15 is the better-sounding pick. 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.
Why pick the Genelec 7050B: A discontinued compact studio subwoofer with five channel inputs and automatic startup, built for small monitoring setups. The tradeoff: Output is low for the price, averaging only 100.3dB from 40 to 80Hz, so it suits small rooms and near field monitoring rather than a home theater.
Buy the Monoprice SW-15. It is rated higher for sound quality; the Genelec 7050B is no longer sold new.
