RCF SUB 9019-AS Description

The RCF SUB 9019-AS redefines what’s possible in a compact, high-output subwoofer for professional touring systems. Powered by a 4000W Class-D amplifier, this sub produces thunderous yet controlled bass with up to 138 dB SPL. Its 19" neodymium transducer, designed with a 4" inside-outside voice coil, ensures fast transient response, low distortion, and exceptional low-frequency reproduction down to 30 Hz. The onboard RDNet platform allows engineers to monitor, manage, and tune every element of their system in real time, while RDTap technology introduces a revolutionary approach to configuration — allowing system setup even when the unit is unpowered. Through RDTap’s contactless communication, presets, EQ, delay, and cardioid settings can be transferred instantly using a smartphone or tablet. With the inclusion of RCF’s proprietary BMC (Bass Motion Control), the SUB 9019-AS eliminates the need for traditional high-pass filtering, delivering full-range low-end response while protecting the transducer. The ACE (Advanced Crossover Engine) ensures seamless phase alignment and precise crossover transitions when paired with RCF full-range speakers. Its tour-ready weatherproof enclosure, Polyurea coating, and included rain cover make it perfect for demanding live and outdoor applications.
