New perspective on linearity

RCF speakers are designed using a proprietary and advanced digital FiR technology, conceived to deliver transparent sound, absolute clarity, and perfect imaging to the listener.
The special FiRPHASE filters allow for coherent distribution of sound for all listeners without phase distortions, ensuring minimum latencies in the system.

Superior compression drivers

The RCF Compression Drivers in pure Titanium are perfect for a crossover point lower than 650 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.

Powerful class D amplifiers

RCF's Class-D power amplifier technology packs huge performance operating with high efficiency into a lightweight solution. NX amplifiers deliver ultra-fast attack, realistic transient response and impressive audio performance. The amplifier features a solid mechanical aluminium structure which not only stabilises the amplifier during transportation but also helps the fan-less heat dissipation. All the NX amplifiers present SMPS power supply section in order to produce maximum output and minimum transportation weight.
