The RCF HDL 50-A is a true active high power speaker system ready to use the touring system for large events, indoors and outdoors. Equipped with 2×12” woofers, 4x symmetrical 6.5” midranges, and two 2” drivers, it offers excellent playback quality and high sound pressure levels with a built-in 2200W RMS powerful digital amplifier that delivers superior SPL, while reducing energy requirement. Using advanced neodymium magnets and a groundbreaking new housing constructed from lightweight plywood and polypropylene, it has a remarkably low weight for easy handling and flying. The HDL 53-AS is the ideal flyable bass complement for the HDL 50-A array system.

UPGRADE YOUR HDL 50-A WITH 4K
The 4K amplifier is an essential part of the HDL 50-A reengineering effort. The 4000 W RMS Class-D power operates at very low impedance producing a quick and detailed transient response, while the high damping factor improves sound quality and detail.
The HDL 50-A 4K power section is tailored to the transducers and the cabinet design to reach excellent efficiency, low distortion, and high signal-to-noise ratio. 4000W RMS class-D amplifier – 1000W for the HF, 1000W for the Midrange section, and 1000W+1000W for the LF for a quick and detailed transient response.
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 achieving coherent distribution of sound for all listeners without phase distortions, ensuring minimum latencies to the system.
V-SHAPED SYMMETRICAL DESIGN
The symmetrical design of the cabinet produces identical left and right coverage. The component positioning and special DSP crossover filtering of the HDL 50-A take care of the constant directivity without spots of break up or attenuation. The originally designed V-SHAPED front baffle provides:
- Coplanar midranges and woofers
- Controlled LF dispersion
- Central space to host the HF guide
4 PATH WAVEGUIDE
The custom 4PATH designed waveguide allows a precise coverage of 90 x 10 degrees, while also delivering a superb, linear high-frequency response. The unique shape of the four ducts forming the guide creates an ideal isophasic load from 800 Hz to the highest audible frequencies.
NEODYMIUM RCF PRECISION TRANSDUCERS
HIGH FREQUENCIES – The two ND 840 large format compression driver deliver one of the key advantages of the HDL 50-A: the 3.0” voice coil allows a crossover point of 800 Hz and therefore this driver can produce almost all of the vocal range. This allows for better coverage and superior efficiency.
MID FREQUENCIES – 4 x 2.0” voice coil 6.0” neo midranges – Water resistant fiber doped cone – Polycotton M-roll surround – High power magnetic structure
LOW FREQUENCIES – 2 X 3.0” voice coil neodymium 12” woofers – Water resistant fiber doped cone – Polycotton M-roll surround – Hypervented magnetic structure
NETWORKED CONTROL AND MUCH MORE
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.
