Description
Uncompromising Resolution. Monumental Scale. Pure Audio Realism.
The RBH Reference 6500-SF/R is a tour de force in full-range acoustic engineering. Designed for discerning audiophiles and home theater purists who demand the physical authority of a massive floorstanding tower without sacrificing pinpoint studio accuracy, the 6500-SF/R delivers an incredibly deep, three-dimensional soundstage.
Hand-assembled in the USA, this tower represents the absolute peak of RBH’s design philosophy, combining their highly inert High-Density Fiberboard (HDF) cabinetry with their world-class Reference upgrade package. Whether rendering the delicate acoustic nuances of a high-resolution jazz recording or the explosive, multi-layered dynamics of a modern cinematic soundtrack, this tower commands the room with absolute effortless control.
Elite Reference Driver Technology
Every aspect of the 6500-SF/R has been optimized to eliminate distortion and deliver maximum transient speed:
-
Proprietary Reference AMT Tweeter: Sourced directly from RBH’s flagship systems, a large Air Motion Transformer (AMT) ribbon tweeter handles the high frequencies. By squeezing air at incredible velocities rather than pushing it like a dome, it yields a sweet, ultra-airy high-frequency response extending effortlessly to 40kHz with zero listener fatigue.
-
Reference Aluminum Midrange with Solid Phase Plug: Critical vocal and instrumental ranges are handled by a dedicated 6.5-inch reference aluminum midrange driver. Equipped with a machined solid-metal phase plug that replaces a standard dust cap, this driver eliminates cone-resonance coloration, runs incredibly cool under heavy power, and maintains flawless off-axis dispersion.
-
Dual 6.5-Inch Reference Aluminum Woofers: Delivering deep, physical, and lightning-fast low-end impact are dual 6.5-inch reference-grade aluminum cone woofers. Because aluminum is exceptionally rigid yet lightweight, these drivers start and stop instantly, yielding incredibly tight, textured bass down to a visceral 35Hz without a hint of bloat or overhang.
Key Product Highlights
-
True 3-Way Acoustic Alignment: By dedicating specialized drivers to the high, mid, and low-frequency bands, the 6500-SF/R handles complex, dense musical passages with breathtaking clarity and separation.
-
