RBH Signature Reference 1212N-SF/R – Dual 12" Passive Subwoofer

RBH Sound 1212N-SF/R – Signature Reference Dual 12" Passive Subwoofer

Built to deliver copious amounts of extremely deep and powerful bass with precise control, the 1212N-SF/R passive subwoofer is not for the faint of heart. The 1212N-SF/R features two reference 12-inch long-throw aluminum cone drivers. These reference drivers provide extended frequency response, greater power handling and improved dynamic range. Designed for larger home cinema and listening environments, the 1212N-SF/R delivers an incredible sonic and tactile experience to every movie or music listening session. We recommend using the RBH DA-1802 or DA-2602 subwoofer amplifiers for powering this subwoofer.

Highlights & Key Features

Reference Aluminum Drivers
The 1212N-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 compared to standard drivers. The dual-driver configuration delivers massive output and displacement for the deepest bass possible in larger home cinema and listening environments.

Passive Design & Amplifier Compatibility
As a passive (non-powered) subwoofer, the 1212N-SF/R requires an external amplifier. RBH recommends their DA-1802 or DA-2602 subwoofer amplifiers, which unlock extended bass response down to 18 Hz (±3 dB) with programmed DSP options. The recommended power range is 500 to 2,400 watts. The 1212N-SF/R has all the perks of the powered 1212P-SF/R with the added benefit of customizing your experience with the amplifier of your choosing.

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 1212N-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.
