Two-Way CoEntrant M/H Driver Complex Conic Loudspeaker Modules

Non-powered STX6M loudspeaker modules unite advanced technology and application-driven engineering to bring live sound closer to the ultimate reference point: reality. Patented CoEntrant M/H transducers, 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 and STX Series loudspeakers are an excellent choice for transparent, reference quality performance.


STX6M loudspeakers are non-powered, for use with external amplification.

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.

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.


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.

• 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.
