Description
Lifelike Dialogue. Holographic Soundstaging. Reference-Grade Clarity.
In any premium home theater, the center channel is the absolute heart of the system—responsible for up to 80% of all dialogue and the vast majority of the front soundstage’s localized effects. The RBH Reference 661C-SF/R is a no-compromise, reference-grade center channel speaker designed to deliver stunning vocal realism and seamless off-axis performance.
Hand-assembled in the USA, this speaker upgrades RBH’s standard MTM (Mid-Tweeter-Mid) layout with their elite Reference package. The result is a highly articulate, ultra-low-distortion transducer that matches perfectly with any 6.5-inch Signature or Reference series speakers to create a completely cohesive, timbre-matched front soundstage.
Elite Driver Technology & Acoustic Design
-
Proprietary Reference AMT Tweeter: The centerpiece is a large, highly efficient Air Motion Transformer (AMT) super-tweeter. By squeezing air rather than pushing it like a traditional dome, it reacts instantly to transient details, offering an effortless, airy high-frequency presentation up to 40kHz.
-
Dual 6.5-Inch Reference Aluminum Woofers: Flanking the tweeter are dual proprietary 6.5-inch anodized aluminum cone woofers. Upgraded with machined solid metal phase plugs instead of standard dust caps, these woofers offer excellent thermal cooling, minimize cone breakup under heavy loads, and drastically improve off-axis midrange dispersion.
-
Heavyweight HDF Cabinetry: While most center channels use standard MDF, the 661C-SF/R is built with a heavily braced ¾-inch High-Density Fiberboard (HDF) enclosure. This completely inert cabinet eliminates unwanted box coloration, ensuring that voices remain clean, clear, and perfectly intelligible.
-
Highly Optimized D’Appolito Layout: The precise driver alignment keeps horizontal directivity wide and vertical dispersion focused. This means every seat on the couch enjoys the same pristine, uncolored dialogue and seamless panning effects.
