#29 OEM Systems ICBM: $1,725 eBay
Pros: A hidden in-wall subwoofer system with four 8 inch drivers that fits a standard stud bay and delivers strong movie bass. Independent CEA-2010 testing (4-driver configuration) records 97.5 dB at 20 Hz and 117.0 dB (avg of 3/4 bands) through 40-80 Hz. The sealed in-wall enclosure fits inside a standard 2x4 stud bay, invisible behind a paintable grille.
Cons: Custom-install product: no combined system weight is published, and a 2-driver variant of this kit is not currently sold anywhere verified, so only the 4-driver configuration is listed here.
