NOMINAL DATA
The CR72i 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. The LF and HF sec-
tions 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-termi-
nal barrier strip, designed to accommodate bare wire, tinned leads or
spade lugs. For safety, the black cloth grille is attached with
multiple threaded fasteners.
All external components feature a textured, non-reflective, black
finish.
