Highlights & Key Technologies

High-Power 12″ Aluminum Woofer
A single 12″ (305mm) Reference Aluminum Cone subwoofer driver with high-power handling delivers exceptional accuracy and fast transient response. With recommended amplifier power of 300 - 800 Watts, the 12NS is best paired with a single channel of the DA-2602DSP or bridged mono operation of the DA-1202DSP.

G.A.D.S. Technology
On select, sealed-only speaker systems, RBH’s patent-pending G.A.D.S. (Granular Acoustic Damping System) technology is employed. Not only does it have mass-loading effects, which can further improve the rigidity of the cabinet, it is also an excellent acoustic absorber. The marvel of this technology is that while the granular particulates may occupy a significant amount of space in the enclosure, the impact on the total volume is negligibly affected, therefore the tuning of the box is near unaffected. In the 12NS, the combination of G.A.D.S. and the acrylic polymer panels makes the subwoofer so inert that you will experience bass with an unreal tightness, accuracy, and musicality; the sub driver does all of the talking, significantly reducing extra energy that is otherwise emitted from the cabinet, resulting in speed, precision, and linearity, with lightning transients and infrasonic capabilities.

Damping Materials
Wool is an excellent acoustic absorber, with a greater density and absorptive ability over polyfill, and is the material of choice for any sealed enclosures or chambers. For ported enclosures, cabinets are lined with high-quality 1-inch foam, which is a terrific absorber and ensures nothing is projected out of the ports.

Cabinet Anti-Resonance Lining
Each UNRIVALED speaker cabinet is internally lined with an anti-resonance material. This material is made from rubber and aluminum and is adhered to the internal walls of the speaker, effectively adding to the absorption of unwanted vibrations.

Internally Wired with Kimber Kable
As part of the no-compromise pledge with UNRIVALED systems, RBH utilizes Kimber wire with their tried and true braided geometry, which further improves crosstalk rejection and external influences.

Acrylic Polymer Damping Panels
To further the performance of the speaker, as well as cosmetics, side panels made from acrylic polymer solid surface, which has a density similar to granite, can drastically improve the rigidity of the speaker, which substantially reduces cabinet resonance, providing several benefits including reducing smearing, improved imaging, improved soundstage, tightened response, and improved clarity. On the 12NS, the acrylic polymer side panels are optional.

Stackable Design
These subs are even stackable for endless power and creative applications.

Internally Braced Heavy-Duty HDF Cabinet
Constructed of internally braced heavy-duty High Density Fiberboard (HDF), the sealed cabinet is finished in Satin Black or White Paint. Individually hand assembled and tested. Cabinet made in USA of High Density Fiberboard (HDF).

Magnetically Attached Grille
A 3/4″ MDF magnetically attached grille is included, available in Black or White fabric.
