PRODUCT INFORMATION

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.
