RCF - SUB 18-AS
RCF's SUB 18-AS active subwoofer delivers a full, dense and deeply physical sound, designed to make the space vibrate without ever blurring the sound message. The bass descends with assurance, remaining legible even at high levels, and retaining a feeling of control that immediately reassures the ear. Each impact gains in relief, each bass finds its place, with a rapid response and a dynamic range that give life to live performances and DJ sets alike. The SUB 18-AS RCF transforms electrical energy into a coherent sound foundation, with that extra character that makes you want to turn up the volume and smile behind the console.
Presentation
Thanks to its 2200 W Class D amplification, the cabinet delivers a clean, fast attack, with an energy reserve that remains stable over time, even in very demanding configurations and during extended performances.
The integrated Bass Motion Control processing allows you to exploit the lowest frequencies without compromising the mechanical stability of the loudspeaker, precisely adjusting the excursion to preserve the linearity and coherence of the audio signal.
Designed to accompany 10", 12" or even 15" full-range speakers, this active subwoofer helps to balance the overall system, reinforcing the lower end of the spectrum without weighing down the mix, simplifying adjustments in the field.
The polyurethane-coated multi-ply wood cabinet effectively protects the electronics and transducer, while withstanding the stresses of frequent transport, with a structural rigidity conducive to clean reproduction of low frequencies.
