RCF SUB 18-AX – Professional active 18 inch subwoofer with DSP
The RCF SUB 18-AX is a powerful professional active 18 inch subwoofer for DJs, bands, live music, events, rental companies, and mobile PA systems. This subwoofer combines powerful low-end reproduction with extensive DSP capabilities, offering much more than just extra bass.
The SUB 18-AX is equipped with an 18 inch woofer with 4 inch voice coil and a powerful 2,200 Watt Peak Class-D amplifier. This allows the subwoofer to reach a maximum sound pressure level of no less than 135 dB SPL. The frequency range spans from 35 Hz to 120 Hz, convincingly delivering both deep sub-bass and powerful punch.
A major advantage of the AX series is the extensive built-in DSP. Via the 2.4 inch color touchscreen, settings such as crossover, equalizer, routing, delay, and system configurations can be adjusted. The SUB 18-AX also features eight recallable snapshots and a parametric 8-band EQ.
For professional PA systems, the crossover presets and top/sub alignment are particularly interesting. These allow the subwoofer to be precisely tuned to various RCF top speakers. The built-in delay can be set up to 45 meters, and special settings are available for cardioid configurations and 2.1 systems.
The RCF Bass Motion Control technology monitors woofer excursion, enabling powerful low-end reproduction without unnecessary limiting. This keeps the bass dynamic and controlled.
Remote control is also possible. With the RCF LiveRemote app, settings such as crossover, system EQ, and delay can be adjusted from a smartphone or tablet. This makes the SUB 18-AX particularly interesting for professional sound engineers and rental companies.
The housing is made of high-quality plywood and finished with a durable polyurea coating. The steel grille protects the woofer during transport and use. Thanks to the M20 pole mount, an RCF top cabinet can be placed directly on top of the subwoofer.
This makes the SUB 18-AX a versatile subwoofer for both smaller mobile productions and serious professional PA applications.
