Description
The RCF NX45-A Active Two-Way Multipurpose Speaker is an active speaker specifically designed to be the everyday tool for rental companies and professional musicians. It’s one of the most flexible speaker for deploying high-power and pristine sound as a stand-alone FOH system or as a satellite (with subwoofer) but either as a stage monitor or a front, down or side fill speaker.
New Perspective on Linearity
RCF speakers are designed using a proprietary and advanced FiR filtering technology, conceived to deliver transparent sound, absolute clarity and perfect stereo images to the listener. The special FiRPHASE filters allow to achieve coherent distribution of sound for all listeners without phase distortions, ensuring minimum latencies to the system.
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.
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.
