Renkus-Heinz ST or STX5M2

High Power Mid/High CoEntrant Complex Conic Loudspeakers

Self-powered PowerNet ST5M2R and non-powered STX5M2 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.


STX5M2 loudspeakers are non-powered, for use with external amplification.

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

Choose the STX5M2 with external bi-amplification, or go 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. Select the STX5M2 when the project dictates the use of external amplifiers and the self-powered PowerNet ST5M2R for convenience and control in other applications. 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 arrayability 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.
