PRODUCT INFORMATION
The CSC723 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 “stadium” seating auditoriums, where front-to-back coverage
provides a difficult challenge for even the best conventional
systems.
The three-way CSC723 features a multicomponent modular design
which allows quick installation, with little or no assembly required
on site.
The mid-range and high frequency horns feature an unusual asym-
metrical 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-inch exit driver, and also features a controlled collapsing pattern
at the very highest frequencies, which compensates for the screen’s
effect of widening the pattern, 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 “VA4” phase plug. The unique
radial design of the VA4phase plug significantly reduces throat
distortion and frequency “time smear”, resulting in noticeably
clearer, more natural sounding dialog.
The low frequency section incorporates 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.
