#73 RBH Sound Unrivaled 21-SF/R: $11,995 eBay
Pros: Manufacturer-supplied CEA-2010 data records 112.3 dB at 20 Hz and 118.8 dB through 40-80 Hz, with a passing result down to 10 Hz. The 21” carbon fiber driver and 4,000W thermal power handling gave this sub the first Extreme Bassaholic room rating on record.
Cons: At around 333 lbs, moving or placing this cabinet is a multi-person job, and the price puts it well outside typical home theater budgets.
How it compares: Just above it: JL Audio Fathom f113 - $9196 cheaper. Just below it: Velodyne Acoustics DD-15+ - $7195 cheaper.
