APPLICATION

• For small to large cinemas

• Passive 2-way surround channel loudspeaker

• THX®-approved

PRODUCT INFORMATION

The CR82 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 a 12-in woofer and
a 1.4-in exit compression driver mounted coaxially 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 CR82 is specifically engineered to cover a larger seating area
with higher quality, higher output sound than traditional cinema
surrounds. With 250 Watts AES standard power handling and a 90°
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
sion pattern lets CR82’s be used in cinemas with low ceilings without
sacrificing coverage of fringe seats.

The passive crossover/filter network included in the CR82 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 15° 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.

The input connector – a 2-terminal barrier strip that accommodates
bare wire, tinned leads or spade lugs - is located on top of the
enclosure. The enclosure features a textured black finish to elimi­nate visual intrusion of visible surrounds. For safety, the cloth grill
is attached with multiple threaded fasteners.

CINEMA SERIES

COMPONENTS & CONSTRUCTION

The CR82 two-way, passive, full range cinema surround loudspeaker
system includes a 1.4-in exit compression driver mounted on EAW’s
proprietary WGP® (Wave Guide Plate®) mounted coaxially within a
12-in cone transducer on a slanted baffle. The LF and HF sections are
integrated with a complex, multicomponent passive crossover/filter
network which tailors HF response to match the SMPTE/ISO 2969
response curve.

The enclosure is constructed of 3/4-in Medium Density Fiberboard
(MDF). Extensive internal bracing is employed to minimize panel
resonances resulting from the large acoustical energies generated
within the enclosure while maximizing acoustical energy transfer
into the audience area.

Input connectors, located on the top of the enclosure, are 2­terminal barrier strip, designed to accommodate bare wire, tinned
leads or spade lugs. For safety, the black cloth grill is attached with
multiple threaded fasteners.
