RCF HDL 20-A 1,400-watt Dual 10-inch Active Line Array Module

The RCF HDL 20-A is a 1,400-watt peak active line array module built for professional touring and installed sound. Each module houses two 10-inch woofers and a 2-inch compression driver, powered by an onboard 2-way digital amplifier with advanced DSP processing. Peak SPL output of 135 dB means these modules can fill large venues with clear, powerful sound.

The solid machined aluminum structure serves double duty as a structural frame and fan-less heat sink, so the module runs silently even at high output levels. Built-in DSP includes cluster correction, HF projection compensation, and dedicated presets for indoor and high-curving configurations. The 100-degree horizontal and 15-degree vertical coverage pattern provides controlled dispersion that’s essential for array performance. Soft limiters and thermal/RMS protections keep everything safe under demanding conditions.
