TECHNICAL SPECIFICATIONS CSC923X
APPLICATION • For the largest cinema screen channel applications • Bi-amplified
PRODUCT INFORMATION The CSC923X represents a major advancement in cinema screen channel speaker design. Incorporating many new EAW engineering breakthroughs, the CSC723X is designed to provide optimal coverage in all cinemas, especially “stadium” seating auditoriums, where front-to-back coverage provides a difficult challenge for even the best conventional systems. The bi-amplified three-way CSC923X 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.
DESCRIPTIVE DATA Part Number LF Subsystem MF Subsystem
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 dual low frequency sections incorporate EAW’s “push-pull” driver arrangement. Each driver pair is out of phase relative to each other both physically and electrically, yet their product is acoustically in phase, substantially lowering mechanically induced distortion. The CSC-MFX mid-frequency section includes an internal passive crossover network, which provides frequency division for the mid and high frequency sections.
