Technical Specifications CR82
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 2-

leads or spade lugs. For safety, the black cloth grill is attached with
multiple threaded fasteners.
