About the RCF HDL 20-A
The RCF HDL 20-A is an active two-way line array module designed for live sound reinforcement and installed sound situations. It is powered by a 1400 Watt peak (700 Watt RMS) digital amplifier and reaches a maximum SPL of 135 dB across a 55 Hz to 20 kHz frequency response. Two 10-inch woofers handle low-end reproduction while a 3-inch voice coil compression driver delivers vocal clarity. A powerful onboard DSP manages the input section with selectable presets, including options for indoor and high curving situations, as well as cluster and HF projection correction. The composite PP enclosure is structurally reinforced with wood, and variable rigging hardware supports fast, reliable deployment.
RCF HDL 20-A — buyer FAQs
What is the RCF HDL 20-A and what is it designed for?
The RCF HDL 20-A is an active two-way line array module built for live sound reinforcement and installed sound applications. It combines a 1400 Watt peak digital amplifier with onboard DSP, two 10-inch woofers and a 3-inch voice coil compression driver. Its variable rigging mechanics and selectable DSP presets, including indoor and high curving options, are designed to make deployment fast and straightforward.
Who makes the HDL 20-A and where does it sit in the RCF range?
The HDL 20-A is made by RCF, an Italian audio manufacturer founded in 1949 in Reggio Emilia that designs its own transducers and loudspeaker systems. Within the RCF range it sits as an active line array module aimed at professional live and installed sound, and is complemented by the HDL 18-AS, a flyable bass module designed to work alongside the HDL 20-A array system.
What are the key specifications of the RCF HDL 20-A?
The HDL 20-A delivers 1400 Watt peak power (700 Watt RMS) and reaches a maximum SPL of 135 dB. Its frequency response spans 55 Hz to 20 kHz. The cabinet is a composite PP enclosure with structural wooden reinforcement, and the DSP section includes cluster and HF projection correction alongside presets for different deployment scenarios.
What should I check when buying a used RCF HDL 20-A?
Check that the amplifier powers on correctly, that both 10-inch woofers and the compression driver reproduce sound without distortion, and that the DSP presets and input section function as expected. Inspect the composite cabinet and rigging hardware for damage that could affect structural safety. Used HDL 20-A units on 10K Used carry a 21-day warranty covering major functional faults; full details are in the buying guide at 10kused.com/used-av-equipment-guide/.
What drives the price of a second-hand RCF HDL 20-A?
Used HDL 20-A pricing depends on overall condition, the state of the rigging hardware and cabinet, age, and whether accessories such as rigging frames or a flight case are included in the package. Configuration within a larger array (number of modules available together) can also influence value. Check the live listings on this page for current asking prices and any Make an Offer options.
