Description
The RCF SUB 905-AS MK3 is a high-performance 15” powered subwoofer designed for professional audio applications, including live sound, DJ performances, and touring. Engineered with a powerful 2200W Class-D amplifier and a high-excursion 15” woofer, it delivers deep, punchy bass with remarkable clarity and impact. With a frequency response of 40 to 120 Hz and a maximum SPL of 133 dB, this subwoofer provides exceptional low-end extension for any venue or event.
