Short answer: the Harbinger V2218S. It ranks #15 of 110 subwoofers by sound quality at $3495; the Funk Audio Classic 18.0 ranks #16 and costs $4893.35, which makes this an easy call rather than a real tradeoff.
What the Harbinger V2218S offers: Independent CEA-2010 testing records 81.7 dB at 20 Hz and 128.9 dB through 40-80 Hz. The ported, front enclosure with 18” (457mm) driver delivers formidable 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 825.5H x 673.1W x 754.4D mm cabinet and 40.8 kg mass still require deliberate placement and calibration.
What the Funk Audio Classic 18.0 offers: Independent CEA-2010 testing records 106.5 dB at 20 Hz and 127.3 dB through 40-80 Hz. The sealed enclosure with 18” (457mm) driver delivers formidable 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 571.5H x 558.8W x 520.7D mm cabinet and 52.2 kg mass still require deliberate placement and calibration.
