ST6MR 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 Two-Way Design, Unparalleled Performance
500 Hz to 18 kHz frequency response, high-level 130 dB peak SPL performance

• Flexible Input Configurations
Choose passive inputs, or go self-powered with the PM2MHR Power Net Bi-Amplifier with RHAON for flexible analog and multi-channel digital signal distribution, computer control and supervision.

Built-In Mid-High Crossover in STX6M
Eliminates the need for bi-amplification.

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

• Patented CoEntrant Topology
Integrates the acoustic output of an 8-inch cone and a 1-inch HF driver into a wideband, high-power true point source

• TRAP (True Array Principle) Design
ST6M/44R and STX6M/44 Models are true 40° TRAP modules that combine seamlessly to produce a phase aligned wavefront virtually free of lobing. The /64 and /94 models can be turned into TRAP modules by rotating their horn 90 degrees.

• Choice of Coverage Patterns
Choose between tightly controlled 60° by 40°, 90° by 40° and 40° by 40° coverage patterns.

PM-2MHR PowerNet Bi-Amplifier

The PM-2MHR, the heart of the PowerNet ST6MR, is a new kind of intelligent electronic system. The heart of the ST6MR, it combines Class D digital tri-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 arrayability are critical issues and outstanding sonic performance is required.

• Distributed systems in sports arenas and stadiums.

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

• Side fill in all types of sound reinforcement systems.

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