RCF S 15 Passive Bass Reflex Subwoofer

The S 15 steps up from the S 12 with a 15-inch woofer on a 3.0-inch voice coil, handling 500W RMS (2000W peak) at 8 ohms and reaching 126 dB max SPL. Its efficient design pushes response below 35 Hz from a compact enclosure, output that would normally need a much larger box.

M10 inserts on the top and rear panels let a single unit fly in permanent installations, and Euroblock input/output connectors keep wiring simple with the rest of the S series. It suits venues from clubs and bars up through theatres and corporate spaces where a fast, controlled low end matters more than touring-level headroom.
