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.

Compact Design
Outstanding, full-range ± 3 dB, 70 Hz to 18 kHz performance in a compact, space-saving design.

RHAON Renkus-Heinz Audio Operations Network
All self-powered CF121 series cabinets 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 12-inch 2-way system, order the CFX121M. For full-range nearfield applications, the CF121M-2 is a logical choice. If you need Ethernet-based audio operations networking, order the RHAON empowered CF121M-2R.

Exclusive 90° by 60° Complex Conic Design
Provides constant beamwidth/directivity without the problems of conventional rectangular horns; can be rotated 90° within the cabinet for wide or deep listening spaces. 

2" Extended Range Titanium HF Driver
Provides smooth, low distortion high frequency performance to 18 kHz and beyond.

Heavy-Duty 12" Woofer
Easily handles 500 Watts of program power.

Built-in Crossover
Includes EQ and high frequency protection; in the CFX121M eliminates need for a separate electronic crossover and bi-amplification.

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.


  • Stage monitor and foldback systems.
  • Ideal for both install and portable applications ranging from houses of worship, schools, night clubs, performing art centers and portable/rental systems.
