RCF HDL 28A Description

The RCF HDL 28A is engineered for professional touring applications, offering high-output performance with precision coverage and intelligibility. It features two neodymium 8" woofers and a high-output 3" titanium compression driver, all housed in a durable composite enclosure. The symmetrical cabinet design ensures consistent left/right coverage, while the 4PATH waveguide and FiRPHASE filtering provide ultra-linear phase response and accurate sound imaging. Its integrated 2200W Class-D amplifier delivers massive headroom with an SPL of up to 135dB, and the onboard 32-bit/48kHz DSP handles crossover, filtering, and protection with surgical precision. The HDL 28A is fully compatible with RCF’s RDNet software for advanced networked control and real-time system tuning. The module includes robust rigging hardware for fast, ground-based angle adjustments and array configurations. It’s the ideal solution for scalable, professional PA setups where quick deployment and consistent performance are critical. For full-range performance, pair the HDL 28A with the flyable HDL 36-AS subwoofer, designed as its perfect low-end match.
