RCF HL 35-S 8ohm Flyable 15″ Passive Subwoofer

The HL 35-S White is a high-output passive subwoofer built to complement the HL 6 line array system. Housed in a sturdy Baltic birch plywood cabinet finished in white (RAL 9003), it features a powerful 15” neodymium woofer with a 4.0” voice coil, capable of delivering tight and controlled low frequencies from 40 Hz to 140 Hz. With 3600 W peak power and a maximum SPL of 134 dB, the HL 35-S White ensures exceptional performance in flown arrays or ground-stacked configurations. Designed with HL 6-compatible rigging hardware and an M20 threaded pole mount, it offers versatile deployment options. The steel grille, backed with transparent acoustic foam, adds durability while protecting the components from dust and debris—making it ideal for corporate AV, worship spaces, or fixed sound installations that demand both performance and aesthetics.
