PRELIMINARY INFORMATION
COMPONENTS & CONSTRUCTION
The CR71 2-way, passive, full range cinema surround loudspeaker
system includes one 8-in cone transducer mounted in an optimally
vented enclosure and one 1-in soft dome driver coupled with a
WGP®. The subsystems are integrated with a complex, multicompo-
nent passive crossover/filter network.
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-
terminal barrier strip, designed to accommodate bare wire, tinned
leads or spade lugs. The enclosure is finished in flat black polyure-
thane and includes a black cloth grill. For safety, the grill is attached
with multiple threaded fasteners.
