#42 Elemental Designs A7S-450: $499 Discontinued eBay
Pros: Independent CEA-2010 testing records 103.4 dB at 20 Hz and 122.3 dB through 40-80 Hz. The sealed enclosure with 18” (457mm) driver delivers formidable upper-bass output for movie effects and music.
Cons: 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 565.1H x 565.1W x 565.1D mm cabinet and 63.5 kg mass still require deliberate placement and calibration. Discontinued.
How it compares: Just above it: Funk Audio Classic 21.0L - $2496 more. Just below it: Power Sound Audio (PSA) XV30FSE - $4496 more.
