Commentary
A large speaker system for theaters developed for small theaters and post-production studios with up to 250 seats.
A 38 cm cone type woofer is installed in the low range.
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.
