• THX® Approved

The CSC923 represents a major advancement in cinema screen
channel speaker design. Incorporating many new EAW engineering
breakthroughs, the CSC723 is designed to provide optimal coverage
in all cinemas, especially “stadium” seating auditoriums, where
front-to-backcoverage provides a difficult challenge for even the best
conventional systems.

The three-way CSC923 features a multicomponent modular design
which allows quick installation, with no assembly required on site.

The mid-range and high frequency horns feature an unusual asym­metrical flare design, which provides a narrow pattern at the rear of
the room, and a wider pattern at the front of the room. This design
minimizes energy radiated at the side walls, while concentrating
sound in the seating area. The high frequency horn is coupled to a
2-in exit driver, and also features a controlled collapsing pattern at
the very highest frequencies, which compensates for the screen’s
effect of widening the dispersion, thus resulting in a constant pat­tern in the seating area.

The single 10” mid-range cone driver is housed in its own subenclo­sure and is coupled to EAW’s patented Radial Phase Plug™. The
unique design of the Radial Phase Plug™ significantly reduces throat
distortion and frequency “time smear”, resulting in noticeably
clearer, more natural sounding dialog.

The low frequency sections incorporate EAW’s “push-pull” driver
arrangement. The drivers are out of phase relative to each other both
physically and electrically, yet their product is acoustically in phase,
substantially lowering mechanically induced distortion.
