Short answer: the Rythmik F18. Both are rated 4.1/5 for sound quality (#85 and #87 of 143 subwoofers), and the Rythmik F18 costs $2,344 against $5,000 for the Perlisten Audio R212s, and with sound quality even, the cheaper one is the better buy.
What the Perlisten Audio R212s does well: A sealed dual 12 inch subwoofer with strong, punchy upper bass for movie effects and music, plus XLR and RCA inputs. The catch: Deep-bass output is more limited than the strong 40-80 Hz result suggests, so it is not the right choice when the lowest movie effects are the priority.
The case for the Rythmik F18: A massive sealed 18 inch subwoofer with tight, powerful bass and balanced XLR inputs, built for big home theaters. The tradeoff: The 520.7H x 520.7W x 533.4D mm cabinet and 115.1 lbs (52.2 kg) mass make this a serious placement and moving commitment.
Buy the Rythmik F18. Both are rated the same for sound quality, and it costs $2,656 less than the Perlisten Audio R212s.
