Product Description
The RCF S8018 II is a high-performance 18-inch subwoofer designed for professional installed sound systems and demanding live sound applications. Engineered for powerful low-frequency reinforcement, it delivers deep, controlled bass response down to 30 Hz with exceptional clarity and output.
At its core is a precision 18" high-excursion woofer featuring a 4" inside/outside voice coil, designed to reduce power compression and improve thermal efficiency for long-term reliability. The bass-reflex enclosure design enhances low-frequency response while maintaining efficiency and tight performance.
Built from rugged Baltic birch plywood and finished with a heavy-duty textured epoxy coating, the S8018 II is designed for durability in permanent installations and touring environments. A protective steel grille, integrated handles, pole mount adapter, and Speakon NL4 connectivity make it both versatile and installation-friendly.
