The RCF HDM 45-A 15’’ powered speaker features a top-quality, 2-channel amplifier, RDNet networked management, RCF precision transducers, the FiRPHASE processing. All of this technology and power comes packaged in compact and rugged cabinet. With onboard bi-amplification, this active speaker has 2,200W of peak power.

While being one of the most powerful speakers in composite material in its category, it delivers clear, detailed and smooth sound from low to very high levels, with low distortion and fast transient response. The HDM concept is inspired by the touring industry, packing in an elegant and lightweight cabinet the maximum reliability and strength for intensive use on the road. Perfect as a main front of house speaker in PA systems, high-powered floor monitor, or unobtrusive infill system when combined with the RCF HDL System speakers.

RDNet is a robust management network and control platform for small, medium and large arena-sized sound systems, as well as complex and extended installations. Based on a proprietary network protocol, RDNet provides intuitive control and monitoring of every connected device/object in the RCF audio system. Each device has DSP to address specific presets or modifications of parameters to single or groups of objects. A network user can change level, delay, EQ (linear phase FiR as well) and other settings, including advanced subwoofer configurations. RDNet is not only designed for loudspeakers—you can control parameters and routing of multiple RCF devices, such as digital matrixes or amplifiers.

The HDM 45-A powered speaker’s low-frequency transducer is a high-power 15’’ neodymium woofer with a 3.5’’ voice coil, delivering a punchy bass. Reproduction of the mid-bass frequencies is accurate, transparent and free from distortion.

The RCF HDM 45-A 15″ active speaker features a ND940 compression driver in pure titanium with a 4″ voice coil, which allows a crossover point at only 650 Hz. This allows a better impulse response, fast decay and superior efficiency. Lightweight and powerful, RCF 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 minimizing distortion and extending low frequency range.
