Highlights & Key Technologies

RBH Sound Reference Driver Package
The 61-SF/R further enhances the capability of the 61-SF by replacing the signature drivers with the RBH Sound Reference Driver package. This upgrade includes the RBH Reference AMT tweeter — measuring 1.38" x 1" (35mm x 25mm) — and the RBH Reference 6½-inch aluminum cone woofer with solid aluminum phase plug, available in silver or black-anodized. This driver package also includes an enhanced crossover circuit. Together, these changes extend clarity, detail, and imaging relative to the standard 61-SF.

HDF Cabinet
The 61-SF/R cabinet is constructed from ¾-inch High Density Fiberboard (HDF) with heavy internal bracing, individually hand assembled and tested in the USA, and available in satin black or white. A magnetically attached black or white high quality fabric grille with a ½" MDF frame is included.

SF Series Compatibility
The 61-SF/R is timbre matched to blend seamlessly with other RBH Sound Signature on-wall, in-wall, and in-room products, providing multi-channel integration across all freestanding, bookshelf, on-wall, and in-wall products in the SF, SV, and SI Series.
