Maybe it’s the FiRPHASE

RCF speakers are designed by using FiRPHASE, a proprietary and advanced FIR filtering technology, conceived for delivering transparent sound, absolute clarity and perfect stereo images to the listener. The FiRPHASE algorithm optimises dynamics, amplitude and phase patterns, ensuring at the same time minimum system latency.
Needless to say, we’re impressed.
