Description
Unrivaled Scale. Extreme Resolution. The Ultimate Flagship Performance.
The RBH Reference 8300-SF/R is a monumental achievement in full-range passive loudspeaker design. Engineered as the absolute crown jewel of RBH’s premier freestanding lineup, this towering 3-way system delivers the jaw-dropping power, physical impact, and visceral depth of a live concert, alongside the surgical, holographic precision of a world-class mastering studio.
Individually hand-assembled and tested in the USA, the 8300-SF/R integrates a massive multi-driver array with RBH’s elite Reference upgrade package. Housed in a dense, heavily braced HDF cabinet, it plunges effortlessly down to a subterranean 25Hz—setting a new benchmark for what is acoustically possible from a passive floorstanding speaker.
The Power of Reference Innovation
The “/R” Reference designation upgrades the tower’s critical acoustic components to deliver a dramatically wider soundstage, absolute transient speed, and breathtaking transparency:
-
Signature Reference AMT Tweeter: Sourced directly from RBH’s most prestigious designs, a high-output 1.38″ x 1″ Air Motion Transformer (AMT) super-tweeter reproduces high frequencies. By squeezing air at incredible velocities rather than pushing it like a dome, it delivers lightning-fast transient speed and shimmering, airy treble up to 40kHz with near-zero distortion.
-
Dual Reference Mid-Woofers with Solid Phase Plugs: The crucial midrange frequencies are handled by dual 6.5-inch reference aluminum cone drivers. Upgraded with machined solid-metal phase plugs that replace traditional dust caps, these drivers eliminate cone-resonance coloration, optimize thermal cooling, and dramatically widen the off-axis midrange dispersion for an exceptionally forgiving listening sweet spot.
-
Triple 8-Inch Low-Frequency Woofers: Anchor the entire sonic presentation with a massive low-frequency array. Utilizing three proprietary 8-inch cast-frame aluminum cone woofers with durable NBR surrounds, this low-frequency engine moves vast amounts of air with absolute speed and authority, producing tight, chest-thumping bass that completely eliminates the need for an external subwoofer.
Key Product Highlights
-
Heavily Braced HDF Cabinetry: To prevent box vibration from robbing the drivers of detail, the cabinet is constructed in the USA from ultra-dense High-Density Fiberboard (HDF). Weighing a massive 91 lbs, this acoustically dead enclosure features advanced internal damping to ensure you only hear the pure, uncolored sound of the drivers.
-
Dual Rear-Firing Ports: Meticulously flared rear-firing bass reflex ports tune the cabinet’s internal air pressure, letting the triple 8-inch woofers expand their low-frequency output down to a flat 25Hz without a hint of chuffing or bloat.
-
Bi-Wire & Bi-Amp Capability: Equipped with dual heavy-duty 5-way binding posts. This allows critical listeners to run the tower in a bi-amplified or bi-wired configuration—making it an ideal partner for high-current audiophile monoblocks or dedicated subwoofer amplifiers like the RBH DA-1802DSP.
