Highlights & Key Features

Reference Aluminum Driver
The 12N-SF/RS features a single 12-inch (305 mm) reference aluminum cone long-throw subwoofer driver. Available in black or silver aluminum finishes, the reference driver provides extended frequency response, greater power handling and improved dynamic range. The sealed cabinet design delivers tight, accurate bass ideal for both home theater and two-channel listening environments.

Sealed Cabinet Design
Unlike the ported 12N-SF/R, the 12N-SF/RS utilizes a sealed cabinet design for tighter, more precise bass response. The sealed enclosure provides accurate, musical bass that is the perfect choice for theaters or two-channel listening enjoyment. The compact form factor makes it easy to place conveniently in any room, and for complete bass coverage, two subs is best — which is easily done due to the size of the 12-SF/RS series.

Passive Design & Amplifier Compatibility
As a passive (non-powered) subwoofer, the 12N-SF/RS requires an external amplifier with a recommended power range of 300–800 watts. RBH recommends their DA-1202DSP chassis amplifier, which unlocks extended bass response down to 24 Hz (±3 dB). The 12N-SF/RS has all the perks of the powered 12P-SF/RS with the added benefit of customizing your experience with the amplifier of your choosing.

Cabinet & Construction
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 premium fabric magnetic grille (3/4" MDF).

SF Series Integration
The 12N-SF/RS 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 Impression, SF, SV or SI Series.
