• For the largest cinema screen channel applications

• Bi-amplified

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.

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.
