Short answer: the Monoprice SW-15. It ranks #14 of 212 subwoofers by sound quality, rated 4.1/5, at $499.99. The RSL (Rogersound Labs) Speedwoofer 10E ranks #183, rated 3.3/5, at $339.34, $160.65 cheaper, which does not close the gap in sound quality.
The Monoprice SW-15 is the better-sounding option. A big 15 inch subwoofer with powerful, punchy bass at a budget price, great for movies in a large room. The tradeoff: Budget-tier design, ported room gain dependency, 66.1 lbs (30 kg) mid-size, and limited dynamic headroom.
Why pick the RSL (Rogersound Labs) Speedwoofer 10E: An affordable 10 inch ported subwoofer that stays composed at high volume, a budget pick for movies. The catch: The boxy cabinet skips the rounded edges of pricier subs in the lineup.
Buy the Monoprice SW-15. It is rated higher for sound quality, and saving $160.65 with the RSL (Rogersound Labs) Speedwoofer 10E does not make up for the sound-quality gap.
