RCF HL 35-S Flyable Subwoofer

The RCF HL 35-S is a professional flyable subwoofer engineered to extend low-frequency performance for the HL 6 line array system. It is designed for touring and installation environments where powerful bass reproduction, controlled dispersion, and seamless array integration are required. Despite its compact flyable design, it delivers extremely high output and precision bass response suitable for demanding professional applications.

At its core, the system features a 15-inch high-power neodymium woofer with a 4.0-inch voice coil, capable of producing tight, controlled, and distortion-free low frequencies. The enclosure is built from durable Baltic birch plywood, ensuring both acoustic rigidity and long-term structural reliability. The subwoofer operates within a frequency range of 40 Hz to 140 Hz, delivering deep and impactful bass that complements full-range line array systems.

With a maximum SPL of 134 dB and peak power handling up to 3600W, the HL 35-S is capable of delivering high-impact low-end performance in large venues, including arenas, concert halls, and outdoor installations. Its design ensures maximum efficiency and low distortion even at high output levels.

The integrated rigging system is fully compatible with HL 6 line array modules, allowing flexible configurations including flown arrays, ground stacking, or hybrid setups. A steel front grille with acoustic foam backing protects internal components from dust and impact while maintaining sound transparency. Additional features such as an M20 pole mount and dual Speakon connectors enhance its versatility in professional setups. The HL 35-S is a reliable and powerful low-frequency extension solution for modern professional sound systems.
