High-Power Quad 12-inch Three-Way Mid/High CoEntrant Complex Conic Loudspeaker System
Non-powered STX9 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 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.
• 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.
