Technical Specifications CR58

CINEMA SERIES

COMPONENTS & CONSTRUCTION

The CR58 two-way full range cinema surround loudspeaker system employs one 15-in cone transducer mounted in an optimally vented enclosure and one 1-in exit, titanium diaphragm compression driver mounted to a 90° x 70° dispersion pattern constant directivity horn. The LF and HF sections are integrated with a complex, multicompo- nent, passive crossover/filter network.

The enclosure is constructed of 3/4-in thickness Medium Density Fiberboard (MDF). Extensive internal bracing is employed to mini- mize panel resonances resulting from the large acoustical energies generated within the enclosure while maximizing acoustical energy transfer into the audience area. A total of eleven 3/8"-16 threaded mounting points facilitate a wide variety of mounting option.

The input connector, located on the top of the enclosure, is a two- terminal barrier strip designed to accommodate bare wire, tinned leads or spade lugs. For safety, the grill is attached with multiple threaded fasteners.
