The CR72i two-way, passive, full range cinema surround loudspeak-
er system is engineered to reproduce today’s full bandwidth digital
surround tracks in smaller cinemas. It features an 8-in woofer and a
1-in dome tweeter mounted in a slanted baffle.
This system is approved by the THX® division of Lucasfilm, Ltd., for
use in THX® certified theaters.
The CR72i is specifically engineered to cover a larger seating area
with higher quality, higher output sound than traditional cinema
surrounds.
The passive crossover/filter network included in the CR72i goes
beyond merely dividing the signal and actually performs critical
equalization functions. This means it will provide more detailed,
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. For safety, the cloth grille is attached with multiple
threaded fasteners.
