Short answer: the Rythmik F18. It ranks #60 of 97 subwoofers by sound quality at $1850; the Perlisten Audio R212s ranks #61 and costs $5000, which makes this an easy call rather than a real tradeoff.
What the Perlisten Audio R212s offers: Independent CEA-2010 testing records 102.7 dB at 20 Hz and 119.2 dB through 40-80 Hz. The sealed enclosure with 2x 12” (305mm) drivers delivers substantial upper-bass output for movie effects and music. Watch for: 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 599.4H x 408.9W x 500.4D mm cabinet and 48.1 kg mass still require deliberate placement and calibration.
What the Rythmik F18 offers: Independent CEA-2010 testing records 106.2 dB at 20 Hz and 119.5 dB through 40-80 Hz. The sealed enclosure with 18” (457mm) driver has the headroom for demanding film bass in a large room. Watch for: The 520.7H x 520.7W x 533.4D mm cabinet and 52.2 kg mass make this a serious placement and moving commitment. A sealed cabinet still needs careful placement and calibration to avoid room-mode peaks.
Buy the Rythmik F18. It ranks higher for sound quality than the Perlisten Audio R212s and costs less, which settles it without a real tradeoff to make.
