STX4 loudspeakers are non-powered, for use with external amplification.

Key Features

• Compact Three-way Mid/High Loudspeaker Module
50 Hz to 18 kHz frequency response, high-level 133 dB peak SPL performance

• Flexible Input Configurations
External bi-amplification.

• Quad-8 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 an 8-inch cone and a 1-inch HF driver into a wideband, high-power true point source

• TRAP (True Array Principle) Design
ST4R and STX4 loudspeakers are true 40° TRAP modules that combine seamlessly to produce a phase aligned wave front virtually free of lobing.

• Choice of Coverage Patterns
40° by 40°, 60° by 40° and 90° by 40° coverage patterns.

Applications

Virtually any application where directional control and array-ability are critical issues and outstanding sonic performance is required.
