PA subwoofers
RCF SUB 8008-AS Dual 18-inch Active Subwoofer
The RCF SUB 8008-AS is a single active subwoofer cabinet containing two 18-inch woofers with 4-inch voice coils. The 220–240V version is identified by manufacturer part 13000752 and EAN 8024530019945. RCF rates its amplifier at 4,400W peak and its maximum SPL at 137dB at one metre. The current manufacturer page does not state an RMS output figure, so no continuous-power claim is made. Frequency response is stated as 30Hz to 120Hz without an accompanying tolerance. Balanced or unbalanced wired audio uses XLR input and output connections. Eight crossover presets and four cardioid presets support system setup, alongside phase, Deep/Punch and output-delay controls. The black plywood cabinet has a protective polyurea coating, steel grille, two side handles and M20 mounting points for horizontal or vertical use. Power connections use powerCON TRUE1 TOP input and output. Manufacturer dimensions are 550 × 1,180 × 700mm, with an 80kg net weight, so this is substantial venue and touring equipment rather than a lightweight portable speaker. One dual-driver cabinet is supplied as the listing unit; additional speakers, poles, cover, wheels and a specific UK-plug cable are not promised as included.
