RCF SUB 8004-AS – 18-inch touring subwoofer with massive output
The RCF SUB 8004-AS is a professional active 18-inch subwoofer developed for demanding applications in the professional PA world. This powerful subwoofer is excellent for touring, live bands, DJs, festivals, large events, and rental companies where impressive low-end reproduction and high sound pressure are essential.
The SUB 8004-AS is equipped with a powerful 18-inch hypervented woofer with 4-inch voice coil. The woofer is specifically developed for high power handling and very powerful low-end reproduction. The result is a deep, direct, and controlled bass that perfectly complements professional RCF top cabinets and line-array systems.
The built-in 2,500 Watt Peak Class-D amplifier delivers no less than 1,250 Watt RMS. This allows the SUB 8004-AS to reach a maximum sound pressure of 136 dB SPL. The frequency range spans from 30 Hz to 120 Hz, enabling the subwoofer to convincingly reproduce both deep sub-bass and powerful kick and punch.
The DSP-controlled input section offers extensive options to adapt the subwoofer to the used PA configuration. Settings include crossover, phase, Deep/Punch, output delay, and cardioid. This allows the SUB 8004-AS to be accurately tuned to the venue and the top cabinets used.
The cardioid functionality is particularly interesting for professional live productions. By configuring multiple subwoofers correctly, the amount of low-end radiated towards the stage can be reduced. This provides more control over the total sound system.
The housing is crafted from Baltic birch plywood and is designed for intensive touring use. The sturdy steel grille protects the woofer during transport and performances. The rear is also prepared for mounting four wheels, which is particularly practical for a subwoofer of this size.
The SUB 8004-AS can be combined with RCF NXL23-A and NXL24-A, among others, and can be used in configurations with professional RCF line-array systems such as the HDL 10-A and HDL 20-A.
RCF SUB 8004-AS – 18-inch, 2,500 Watt Peak and 136 dB SPL. A professional touring subwoofer for deep, powerful, and controlled low-end.
