Commentary
A large speaker system for theaters developed for large-scale theaters with more than 500 seats.
Four 38 cm cone woofers are mounted in the lower range and are arranged in a unique diamond quad array configuration to minimize interference effects while maximizing output.
This unit uses VGC (Bent Gap Cooling) and SFG (Symmetrical Field Geometry) technologies to achieve both high power and low distortion.
A optimized, aperture, biradial horn and titanium diaphragm driver are used to reduce distortion in the mid-range region, and the direct-to-reverberation ratio is improved by directional control in the mid-range region.
It has a flat front structure that is easy to install on wall baffles.
It is designed to show the performance by the tri-amp drive.
It has been certified by the THX.
