RCF HDL36-AS 3200W Active Flyable Subwoofer Module (Black)

Designed for High-Performance Live Sound Systems
The RCF HDL36-AS is a flyable active subwoofer specifically engineered to integrate seamlessly with the HDL 28-A line array system. Housed in a rugged Baltic birch plywood enclosure and powered by a 3200W peak (1600W RMS) Class-D amplifier, this subwoofer delivers maximum efficiency and a staggering 135 dB SPL. It supports high-impact low-end frequencies from 40 to 140 Hz, making it ideal for concerts, touring productions, and permanent installations in theaters, auditoriums, and performance venues. With integrated DSP and RDNet capabilities, the HDL36-AS offers precise control and optimization in any sound reinforcement scenario.

Optimized for Integration with HDL 28-A Arrays
This subwoofer is designed to be flown in tandem with HDL 28-A modules using the FB-HDL28 flybar, providing consistent phase alignment and sonic cohesion throughout the rig. The integrated hardware ensures fast setup and mechanical compatibility, whether you're deploying a ground stack or full array. Its compact form factor combined with its power output gives system designers flexibility in creating high-output configurations within weight-limited environments.

RDNet Networked Control System for Flexible Management
Featuring RCF’s proprietary RDNet network protocol, the HDL36-AS can be monitored and adjusted remotely from a computer running RDNet software. System engineers can manage EQ, delay, and gain settings, organize zones, and access advanced tools such as air absorption compensation and cluster configuration. Every connected component can be individually controlled or grouped into logical arrays, streamlining workflows for complex sound system deployments.

Premium 15-Inch Neodymium Woofer for Deep Bass Performance
At the heart of the HDL36-AS is a powerful 15-inch neodymium woofer with a 4-inch voice coil, designed to move high volumes of air while maintaining low distortion. This transducer is engineered for high SPL performance and features a water-resistant cone and robust magnetic structure. Whether you're delivering EDM drops or reinforcing kick drums and bass guitars, the HDL36-AS produces tight, articulate lows with authority.

Efficient and Lightweight Class-D Amplification
The onboard amplifier module is a Class-D design that balances power and portability. With a solid aluminum housing for thermal stability and fanless cooling, it ensures reliability even under continuous operation. The switch-mode power supply (SMPS) helps reduce overall system weight while maintaining headroom and transient response. This ensures efficient use of power across all output levels without compromising performance.

Durable Cabinet and Road-Ready Mechanics
The HDL36-AS enclosure is built from high-quality Baltic birch plywood and coated for scratch and moisture resistance. Its front grille is powder-coated steel backed with protective acoustic foam to guard the transducers against dust and debris. With integrated rigging points, carry handles, and a modular form factor, this subwoofer is easy to transport, hang, and maintain, whether you’re setting up for a corporate AV show or a large-scale concert.

Advanced DSP and FiRPHASE Technology for Accurate Sound
Internal DSP handles EQ, level adjustment, and timing alignment, accessible via RDNet or local controls. RCF’s proprietary FiRPHASE technology ensures phase-consistent, linear frequency reproduction across the audience area. This means better intelligibility, tighter bass response, and more uniform sound coverage throughout the venue—essential for professional touring and fixed installations.
