High Power Mid/High CoEntrant Complex Conic Loudspeakers

Self-powered PowerNet ST5M2R Series loudspeakers unite advanced technology and application-driven engineering to bring live sound closer to the ultimate reference point: reality. Patented CoEntrant Mid/Hi transducers, Class-D digital tri-amplification, and unique innovations like our Complex Conic Horns combine to deliver natural sounding music and intelligible speech. Wherever audiences and operators demand superior performance and ease of use, ST/STX Series loudspeakers are an excellent choice for transparent, reference quality performance.


ST5M2R PowerNet loudspeakers are RHAON empowered for flexible analog and digital signal distribution and loudspeaker management and control over a CAT 5 Ethernet network.

Key Features

• Compact Three-way Design – Unparalleled Performance
Accurate, 350 Hz to 18 kHz frequency response, high-level 138 dB peak SPL performance

• Flexible Input Configurations
Self-powered with the PM3R PowerNet Tri-Amplifier with RHAON for flexible analog and multi-channel digital signal distribution, computer control and supervision.

• High Output CDT-2A CoEntrant Driver
CDT-2A CoEntrant driver with 3-inch throat, plus a 10-inch mid-range transducer with 3-inch throat and dual Complex Conic Array guides provide 350 Hz to 18 kHz response, 138 dB peak SPL.

• Exclusive Complex Conic Design
Provides constant beamwidth/directivity without the issues associated with conventional rectangular horns.

• Patented CoEntrant Topology
Integrates the acoustic output of a 10-inch cone and a 2-inch HF driver into a wideband, high-power true point source

• TRAP (True Array Principle) Design
ST5M2/42R and STX5M2/42 models are true 40° TRAP modules that combine seamlessly to produce a phase aligned wave front virtually free of lobing.

• Choice of Coverage Patterns
Choose between tightly controlled 40° by 20° and 90° by 20° coverage patterns.

PM-2MHR PowerNet Tri-Amplifier

Passive or self-powered and networked, choose the system configuration that meets your needs. The PM-2MHR, the heart of the PowerNet ST5M2R, is a new kind of intelligent electronic system. It combines Class D digital bi-amplification with RHAON the Renkus-Heinz Audio Operations Network for comprehensive DSP controlled signal processing and control.

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 cabling.

The PM-2MHR offers dual analog inputs, dual CobraNet inputs and an AES3id serial input. The on-board DSP includes eight bands of parametric EQ, high and low shelving filters, delay and input level control, and is easily configured using RHAON software. Critical operating parameters such as signal clipping, amplifier output voltage and current, and temperature are continually monitored with automatic alert functions.


Virtually any application where directional control and array-ability are critical issues and outstanding sonic performance is required.

• Distributed systems in sports arenas and stadiums.

• As a companion to the ST5LR and STX5L low frequency enclosures in high-power 2-box systems.

• Multi-channel A/V playback systems, live sound and music systems in dance clubs (with optional subwoofers)

• Side fill in all types of sound reinforcement systems.

• Array modules for theatrical and concert sound systems, sound reinforcement systems in houses of worship.
