Its compact enclosure and modular design ensure it's ready for versatile deployment in professional environments.

Proprietary RCF Components for Superior Audio Performance

At the heart of this RCF line array module are custom-designed transducers that redefine sound quality. Two 10" woofers deliver tight, articulate bass with incredible headroom. Complementing this is a 3" compression driver that ensures crisp high frequencies and vocal clarity even at high SPLs. Together, these components provide transparent sound across the entire frequency spectrum. Designed by RCF, these transducers set the standard for precision and reliability in professional audio systems.

Advanced DSP for Controlled Sound

The HDL 20-A module features integrated DSP that optimizes sound performance based on venue requirements. This digital control system includes HF projection correction, cluster adjustments and presets tailored for indoor and high-curving installations. The intelligent processing ensures consistent audio coverage and tonal accuracy, no matter the configuration. Whether used for live sound reinforcement or permanent installations, the DSP system delivers adaptable functionality and precise sound control for professional-grade applications.

Modular Design for Seamless Line Array Integration

The HDL 20-A's modular design makes it an essential component for scalable line array setups. Multiple units can be coupled vertically to adapt to venue size and audience geometry, creating seamless sound coverage. Its composite enclosure, reinforced with wood, is engineered for durability and outdoor use, ensuring reliable performance in challenging environments. This module's compact form factor and lightweight construction make it easy to transport, install and integrate into larger systems, whether for touring or fixed installations.
