PRODUCT INFORMATION
The CR72 two-way, passive, full range cinema surround loudspeaker
system is engineered to reproduce today’s full bandwidth digital
surround tracks in smaller cinemas. It features an 8-in woofer and
a 1-in dome tweeter loaded with EAW’s proprietary WGP® (Wave
Guide Plate®) mounted in a slanted baffle.
This system is approved by the THX division of Lucasfilm, Ltd., for
use in THX-certified theaters.
The CR72 is specifically engineered to cover a larger seating area
with higher quality, higher output sound than traditional cinema
surrounds. With 150 Watts AES standard power handling and a 110
°
conical coverage pattern, it can be mounted higher than traditional
surrounds. Higher placement lets the system cover a larger area
"across" the room creating a larger area of stereo surround coverage
than traditional surround placement. The WGP’s
® extra wide disper-
sion pattern lets CR72’s be used in cinemas with low ceilings without
sacrificing coverage of fringe seats.
The passive crossover/filter network included in the CR72 goes
beyond merely dividing the signal and actually performs critical
equalization functions. This means it will provide more detailed,
more natural reproduction of any sonic event occurring in the 360
°
aural arena. The crossover/filter network tailors HF response to
match the SMPTE/ISO 2969 response curve.
The front baffle is angled down 20
° to accommodate overhead
mounting. The optimally vented enclosure increases LF response
while limiting driver excursion. This method produces less distortion
and minimizes driver strain while extending LF response to the
lowest octaves.
