The Revel PerformaBe series was designed to redefine performance expectations. The core component of these models is a 1" beryllium tweeter driven by massive 85 mm dual ceramic magnets. This results in higher efficiency, an enhanced dynamic range, reduced distortion and a better performance than achieved through aluminium or titanium tweeters. The low-frequency and mid-range transducers made of ceramics also offer sound rich in details for an outstanding audio performance across the entire frequency range.
