Based in Reggio Emilia, Italy, RCF is one of the rare pro-audio titans that manufactures every single component—from raw voice coils and neodymium magnets to wooden cabinetry and digital DSP—entirely in-house. With the launch of their premium touring division, TT+ Audio, and the flagship GTX Series, the Italian company delivers world-class stadium-grade audio performance.

1. Proprietary Innovations: FiRPHASE 0° Linear Phase Processing

Traditional crossover filters introduce non-linear phase shifts that smear audio transients and create comb filtering when cabinets couple. RCF's proprietary **FiRPHASE** DSP algorithms use advanced finite impulse response filters to achieve **true $0^circ$ linear phase response across the entire audio bandwidth** without adding excessive system latency.

  • The Audible Benefit: Vocals sound intimate and centered, drum transients hit with instant percussive attack, and stereo imaging stays wide and transparent.
