TECHNICAL SPECIFICATIONS CB259X

COMPONENTS & CONSTRUCTION continued

15 mm void-free, gross-grain-laminated birch plywood. Extensive 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 formulated compound which is non-resonant, lightweight and non-reflective.

The LF enclosure has 3 mounting points to allow optimum front/rear positioning of the HF component. The adjustable steel bracket attaching the HF horn to the LF enclosure allow the HF horn to be aimed independently at the LF section in both the horizontal and vertical planes and can be locked once it is positioned.

All components feature a textured black finish to eliminate the reflection of light through perforated cinema screens.

COMPONENTS & CONSTRUCTION

The CB259X is a two way, high-output, passive, full range loud- speaker system intended for use in cinema applications. It features dual 15-in low frequency transducers mounted in a vented enclosure and a titanium diaphragm compression driver mounted to a large, 2- in throat, 90°x40° coverage pattern, constant directivity horn.

The CB259X requires no external active electronic crossover. An internal passive crossover/filter network integrates the LF and HF sections. EAW’s complex, computer-designed passive filter networks are tightly aligned to the loudspeakers they control and go beyond merely dividing the signal, performing critical equalization functions.

The input connector is a 2-terminal barrier strip located on the side of the LF section for convenient access in cramped installation areas. A jumper cable is provided to extend the signal chain to the HF component.

The low frequency enclosure is constructed of 3/4-in thick Medium Density Fiberboard (MDF) with the exception of the baffle which is
