At the heart of the C128Be is a 1-inch (25mm) Beryllium tweeter driven by dual-neodymium magnets. The powerful tweeter is mated to an Acoustic Lens waveguide that seamlessly integrates with the directivity of the companion woofer driver resulting in greater efficiency, improved dynamic range, reduced distortion, and increased power handling compared to aluminum or titanium tweeters.

The 8-inch (200mm) aluminum cone woofer utilizes a Deep Ceramic Composite (DCC) cone 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 push cone breakup modes outside of the passband allowing the driver to maintain ideal pistonic motion throughout its range. DCC cones combine with optimized motor magnetics to deliver improved mid- and low-frequency performance.

Revel PerformaBe crossover networks utilize all film capacitors and air core inductors in the midrange and tweeter circuits. These premium components allow Revel's world-class engineers to extract nuances and details from music that would otherwise be lost. Combined with traditional Revel high-order crossover slopes and proprietary Acoustic Lens waveguide geometry, transducer integration is seamless.
