Technical Specifications CR72
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 elimi-
nate visual intrusion of visible surrounds. For safety, the cloth grill
is attached with multiple threaded fasteners.
COMPONENTS & CONSTRUCTION
The CR72 two-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 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-
terminal barrier strip, designed to accommodate bare wire, tinned
leads or spade lugs. For safety, the black cloth grill is attached with
multiple threaded fasteners.
