18-Inch High Performance Subwoofer (Non-Powered, 4 Ohm)

18-inch High Performance Subwoofer
Sound that makes performances and audiences truly come alive doesn't come easy. But CF/CFX Series loudspeakers put the power of unique Renkus-Heinz developments like Complex Conic horns to work for you. Versatile enclosure designs, go-anywhere hardware and rugged construction help solve your sound reinforcement challenges easily and quickly.

Advanced options like intelligent onboard amplification and RHAON - the Renkus-Heinz Audio Operations Network - help you build sophisticated sound systems that are easy to use. CF18S and CFX18S subwoofers were developed as companion pieces to full range CF / CFX series loudspeakers. They provide the high impact sub bass energy needed in many venues and also serve as a mounting base for the loudspeakers.
