Revel

Revel has introduced a third new PerformaBe model that employs a beryllium tweeter, the F226Be at $7000/pair. This is a smaller floor-standing model and supplements the F126BE and F228BE models introduced last year.

The Revel F226Be joins the PerformaBe series as a compact floor-standing loudspeaker. As part of the PerformaBe loudspeaker line, the F226Be includes a 1-inch (25mm) beryllium tweeter driven by massive 85mm dual ceramic magnets. The powerful tweeter and 5th-generation, ceramic-coated, cast-aluminum Acoustic Lens waveguide seamlessly integrate with the directivity of the companion midrange driver to result in greater efficiency, improved dynamic range, reduced distortion, and increased power handling compared to aluminum or titanium tweeters.

Beryllium is renowned for its remarkable physical properties that make it the ideal material for a high-frequency transducer. Compared to aluminum and titanium tweeter diaphragms, beryllium offers 4.5 times the stiffness and three times more damping and does so at only half of the weight. Beryllium tweeters are the centerpiece of the Revel PerformaBe loudspeaker series. The 5.25-inch midrange and dual 6.5-inch aluminum cone woofers utilize Deep Ceramic Composite (DCC) cones for improved performance. DCC is a plasma electrolytic oxidation process that uses a plasma discharge to create a coarse ceramic coating on both sides of the aluminum core. The deep ceramic layers sandwiching the aluminum core provide constrained layer damping that pushes cone breakup modes outside of the audio passband. This allows the driver to maintain ideal, piston-like motion throughout its range. DCC cones combine with optimized motor magnetics to deliver improved mid- and low-frequency performance.
