Technical Specifications CB2591x CINEMA SERIES

COMPONENTS & CONSTRUCTION

The CB2591x is a high output, passive, two-way, full range loud- speaker system intended for use in behind screen cinema applica- tions. It features dual 15-in low frequency transducers mounted in a compact, vented enclosure and a 2-in exit titanium diaphragm compression driver mounted to a large format 90° x 40° constant directivity horn.

The CB2591x requires no external active electronic crossover. The HF and LF sections are integrated via an internal passive crossover/ filter network. EAW's complex, computer-designed passive filter networks are tightly aligned to the loudspeakers they control and go beyond merely diving the signal, performing critical equalization functions.

The low frequency enclosure is constructed of 3/4-in thick Medium Density Fiberboard (MDF) with the exception of the baffle which is 15mm void-free, cross-grain-laminated Baltic birch plywood. Exten- sive internal bracing is employed to minimize panel resonances resulting from the large acoustical energies generated within the enclosures.

The high frequency horn is constructed from a specially dampened fiberglass which is non-resonant, lightweight and non-reflective.

The LF section includes a two-terminal barrier strip that accomodates bare wire, tinned leads or spade lugs. The input panel is located on the side of the LF enclosure for convenient access in cramped installation areas. A jumper cable is provided to extend the signal chain to the HF component.

The adjustable mounting bracket attaching the HF horn to the LF enclosure can be positioned at one of three mounting points for optimum HF horn placement. It allows the HF horn to be aimed independently of the LF section in both the horizontal and vertical planes and can be locked once it is positioned.
