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.

Powerful 18" Subwoofers
Provide high-impact (128 dB peak SPL on the CFX18S) sub-bass performance.

CFX18S Non-Powered Subwoofer
Same high performance as the CF18S only non-powered. 

High Power, High Performance Woofers
With 4” voice coils, rigid cast-alloy frames and long throw magnetic structures easily handle 900 Watts of program power.

Built-In Lo-Pass Filter
Eliminates the need for a separate electronic crossover.

RHAON Renkus-Heinz Audio Operations Network
Self-powered CF18S series subwoofers are available with RHAON for flexible digital signal distribution, loudspeaker management and control. Whenever you are ready for Ethernet audio networking, your CF/CFX loudspeakers are too; just replace the connector plate with a PF1-200R or PF1-500R RHAON empowered amplifier equipped for connection to the Renkus-Heinz Audio Operations Network. RHAON empowers you with CobraNet digital audio distribution, user configurable DSP for maximum control, remote systems management from any Windows computer, life safety functions and more – all using standard Ethernet hardware and cable.

If you need an outstanding high-power 18-inch subwoofer, order the CFX18S or CF18S-5. For nearfield applications, the CF18S-2 with a 200 Watt PF1-200 is a logical choice. If you need Ethernet-based audio operations networking, order the CF118S-2R or the CF18S-5R; both are RHAON empowered.

PF Series Intelligent Amplifiers
Passive, powered or networked: you can choose the CF/CFX system that suits your needs at any time. At the factory or in the field, the CFX passive connector plate can be easily replaced by a PF1-200 or PF1-500 Class D digital amplifier with loudspeaker specific processing. Their lightweight switching power supplies deliver 70% efficiency at full output, reducing AC requirements and eliminating the need for a cooling fan.
