Description
Symmetrical Precision. Dynamic Articulation. Seamless Versatility.
While many speakers are locked into a single position, the RBH Signature 661-SF is a high-output LCR (Left, Center, Right) monitor designed to master any role in your home theater. Thanks to its symmetrical Mid-Tweeter-Mid (MTM) driver configuration, this powerhouse can be oriented horizontally as a high-performance center channel, or stood vertically to act as pristine front left and right main channels.
Whether you deploy three matching units to create a seamless “wall of sound” behind a projector screen, or use it as a dedicated center speaker, the 661-SF delivers the lifelike vocal texture, uncompressed dynamics, and wide horizontal soundstage that RBH’s Signature Series is famous for.
Key Product Highlights
-
Premium Aluminum Cone Mid-Woofers: Armed with dual 6.5-inch black-anodized aluminum cone mid-woofers. Aluminum’s exceptional stiffness-to-mass ratio ensures lightning-fast transient response and incredibly clean, uncolored mid-bass performance, allowing complex movie soundscapes to resolve with absolute clarity.
-
Liquid-Cooled Silk Dome Tweeter: Flanked by the dual mid-woofers, a premium 1-inch liquid-cooled fabric dome tweeter delivers a smooth, highly detailed high-frequency response with zero listener fatigue, even during marathon movie sessions.
-
Acoustically Dead HDF Cabinetry: Built using heavily braced ¾-inch High-Density Fiberboard (HDF) rather than cheap MDF. This rigid, inert enclosure eliminates unwanted “boxy” cabinet resonances, ensuring that dialogue remains crisp, clear, and perfectly intelligible.
-
Symmetrical D’Appolito MTM Design: The MTM driver layout narrows vertical dispersion to minimize reflections from your floor and ceiling, while keeping horizontal dispersion wide to maximize the home theater sweet spot.
