RCF S 19 Passive Bass Reflex Subwoofer

The S 19 is a high-power single-19-inch passive subwoofer for RCF Installed Sound systems, sized between the traditional 18-inch and 21-inch to combine fast transient response with real low-end reach. The neodymium woofer's 4.0-inch voice coil handles 1500W RMS (6000W peak) at 8 ohms, reaching 139 dB max SPL with a bass-reflex response down to 30 Hz.

The plywood cabinet carries a heavy-duty black polyurea coating and a powder-coated metal grille, and Speakon NL4 connectors handle wiring. This listing includes both the standard finish and a weatherproof (WP) SKU for outdoor and covered installs at the same driver and enclosure specification.
