RCF SUB 18-AX 18-inch Active Subwoofer — Black

The RCF SUB 18-AX is a single powered 18-inch bass-reflex subwoofer for live sound and DJ systems. This black 220–240V version uses manufacturer part 13000836 and EAN 8024530021825. RCF specifies 2,200W peak and 1,100W RMS total amplifier power, with a maximum SPL of 135dB at one metre. Its stated frequency response is 35Hz to 120Hz; no frequency tolerance is supplied here. A 2.4-inch colour touch panel and rotary encoder provide local control, while Bluetooth supports parameter adjustment through the LiveRemote app rather than a claimed wireless audio input. Wired audio uses dual XLR/TRS combo inputs with links and dual XLR crossover outputs. Processing includes crossover presets, eight-band parametric EQ, routing, delay and cardioid configuration tools. The plywood cabinet has a polyurea finish, steel grille, side handles and an M20 threaded pole mount. RCF lists dimensions of 693 × 505 × 685mm and a net weight of 42.9kg. This listing covers one subwoofer, not a complete PA system or pair; no cover, pole, castor kit or UK-plug cable is promised without confirmed package information.
