STX9


STX9 loudspeakers are non-powered, for use with external amplification.



Key Features

• Compact Three-way Design - Unparalleled Performance
Accurate, full-range 40 Hz to 18 kHz frequency response, high-level 142 dB peak SPL performance

• Flexible Input Configurations
Choose external bi-amplification.

• Quad-12 Doublet Low Frequency Design
Provides superior low frequency directionality in both horizontal and vertical planes.

• 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
ST9/44ASR and STX9/44AS Models are true 40° TRAP modules that com bine seamlessly to produce a phase aligned wave front 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 asymmetrical 40° by 40° (+10°, -30°) coverage patterns.






Applications

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 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.
