Highlights & Key Features

Reference Aluminum Drivers
The 1212P-SF/R features two 12-inch (305 mm) reference aluminum cone long-throw subwoofer drivers. Available in black or silver aluminum finishes, these reference drivers provide extended frequency response, greater power handling and improved dynamic range. The dual-driver configuration delivers massive output and displacement for the deepest bass possible in larger home cinema and listening environments.

2,400 Watt DSP Amplifier
The built-in 2,400 watt Class D amplifier with programmed DSP options drives the dual 12" drivers to deliver frequency response down to 18 Hz (±3 dB). The DSP provides extensive software-based control including variable crossover frequency (40–180 Hz), variable crossover slope (6–48 dB/octave), phase control (0–180°) with delay control, and DSP mode switching. The amplifier accepts AC 100–240V ~50/60Hz for worldwide compatibility.

Connectivity
The amplifier panel features XLR inputs with an included RCA adapter for flexible source connection. An XLR LFE output is provided for daisy-chaining additional subwoofers or signal pass-through. The LFE input is DSP mode switchable.

Cabinet & Construction
The vented cabinet features dual front firing ports, designed for flexible cabinet installation and freestanding placement. Constructed from High Density Fiberboard (HDF), the cabinet is individually hand assembled and tested at RBH’s facility. Available in satin black or satin white paint finish with a matching black or white fabric magnetic grille (3/4" MDF).

SF Series Integration
The 1212P-SF/R is part of the RBH Signature Reference SF Series, which provides timbre matched options for multi-channel sound across all freestanding, bookshelf, on-wall and in-wall products in the SF, SV or SI Series.
