SUPERIOR COMPRESSION DRIVERS

The RCF Compression Drivers in pure Titanium are perfect for a crossover point lower than 800 Hz. This allows a better impulse response, fast decay and superior efficiency. Lightweight and powerful, our neodymium drivers are a reference in performance and reliability.

The voice coil features a high-temperature kapton former. The assembly process takes advantage of the RCF proprietary Direct Drive technology. The diaphragm’ s suspension has been designed following extensive studies aimed at minimising distortion and extending low frequency range.
