This page lists all 6 RBH Sound speakers ranked on this site across subwoofers. Each model is shown in the category where it competes, with its current rank and the size of that ranking.
Use the category position rather than the brand name alone: speakers from the same manufacturer can perform very differently by size, price and product family.

Large Home Subwoofers (Over 75 lbs)
Ranked #75 of 109 in Large Home Subwoofers (Over 75 lbs) - 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.

Large Home Subwoofers (Over 75 lbs)
Ranked #35 of 109 in Large Home Subwoofers (Over 75 lbs) - RBH Sound SX-1212PR: $1699 Discontinued eBay
Pros: Independent CEA-2010 testing records 115.8 dB at 20 Hz and 123.5 dB through 40-80 Hz. The ported, bottom enclosure with 2x 12” (305mm) drivers has the headroom for demanding film bass in a large room.
Cons: The 977.9H x 450.8W x 533.4D mm cabinet and 59.0 kg mass make this a serious placement and moving commitment. Ported output does not solve room modes, so careful placement and calibration remain essential. Discontinued.

Ranked #45 of 109 in Large Home Subwoofers (Over 75 lbs) - RBH Sound SV-1212PR: $1499 Discontinued eBay
Pros: Published CEA-2010 specifications list 108.5 dB at 20 Hz and 122.2 dB through 40-80 Hz. The sealed enclosure with 2x 12” (305mm) driver has the headroom for demanding film bass in a large room.
Cons: The 838H x 386W x 581D mm cabinet and 49.9 kg mass make this a serious placement and moving commitment. A sealed cabinet still needs careful placement and calibration to avoid room-mode peaks. Discontinued.
