Highlights & Key Features

Reference Aluminum Driver
The 12N-SF/R 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 down-firing port design combined with the reference driver delivers deep, powerful bass down to 26 Hz in a compact, manageable form factor.

Passive Design & Amplifier Compatibility
As a passive (non-powered) subwoofer, the 12N-SF/R requires an external amplifier. RBH recommends their DA-1202DSP amplifier, which unlocks extended bass response down to 22 Hz and extends the upper range to 150 Hz (±3 dB) with programmed DSP options. The 12N-SF/R has all the perks of the powered 12P-SF/R with the added benefit of customizing your experience with the amplifier of your choosing.

Cabinet & Construction
The vented cabinet features a down-firing port, providing a small footprint compared to output. 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). For complete bass coverage, two subs is best, which is easily done due to the compact size of the 12-SF/R series.

SF Series Integration
The 12N-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.
