Description
Monumental Dynamics. Absolute Musicality. The Ultimate High-Output LCR.
The RBH Premier 821-SF/R (also known simply as the Premier 821) is a massive, reference-grade 2-way freestanding speaker designed to anchor high-fidelity, high-output 2-channel stereo systems and state-of-the-art home theaters alike. Acting as the larger, incredibly potent sibling to the 621-SF/R, this heavyweight LCR (Left, Center, Right) monitor delivers an uncompromised “wall of sound” with the physical authority of a tower and the pinpoint, holographic imaging of a world-class studio monitor.
Individually hand-assembled and tested in the USA, the 821-SF/R features a symmetrical Mid-Tweeter-Mid (MTM) configuration. By pairing dual high-displacement 8-inch reference woofers with a massive flagship Air Motion Transformer (AMT) tweeter in a rigid, sealed enclosure, it provides staggering dynamic range and absolute acoustic truth—making it the ultimate solution for large-scale listening spaces.
Key Product Highlights
-
Flagship 4.72-Inch AMT Tweeter: High frequencies are handled by an exceptionally large 4.72” x 1” (120mm x 25mm) AMT tweeter. Operating via a folded, ultra-lightweight ribbon diaphragm that squeezes air at high velocity, it delivers an airy, highly resolved, and effortless treble response up to 35kHz with near-zero distortion.
-
Dual 8-Inch Reference Aluminum Woofers: Flanking the tweeter are dual 8-inch cast-aluminum basket, black-anodized aluminum cone woofers. These heavy-duty drivers provide the vast surface area and physical displacement necessary to add massive chest-thumping depth, organic body, and realistic weight to instrumentation and low-frequency effects.
-
Sealed High-Density Fiberboard (HDF) Cabinet: Constructed from premium ¾-inch High-Density Fiberboard (HDF) with extensive internal bracing. The completely sealed enclosure guarantees exceptionally tight, fast, and melodic bass transients free from the “chuffing” or smear associated with ported cabinets.
-
Steep 24dB/Octave Crossover Network: A highly sophisticated, premium crossover network centered at 2,200 Hz with steep 24dB per octave slopes ensures that both the dual 8-inch woofers and the massive AMT tweeter operate strictly within their optimal performance zones.
