[. . . ] TECHNICAL SPECIFICATIONS CB259X APPLICATION · For medium cinemas · Passive 2-way screen channel loudspeaker · Requires only one amplifier channel and no external crossover PRODUCT INFORMATION The CB259X two-way passive screen loudspeaker system fills medium-sized theaters with all the high-impact, full-range sound encoded on today's digital soundtracks while reproducing voices clearly and naturally. The two component system includes a BV253C vented dual 15-in low frequency unit and a HK294 high frequency system - a medium format 90°x40° HF horn loading a large diaphragm 2-in exit compression driver. [. . . ] The bracket 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. The LF section includes a barrier strip that accommodates bare wire, tinned leads or spade lugs. A jumper cable is supplied to extend the signal chain to the HF component. The input connector is located on the side of the enclosure for convenient access in cramped installation areas. HF component connection is made directly on the compression driver.

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. NOMINAL DATA Frequency Response +3 dB 42 Hz - 17 kHz Axial Sensitivity (dB SPL, 1 Watt @ 1m) Full Range 101 Impedance (Ohms) Full Range 4 COMPONENTS & CONSTRUCTION The CB259X is a two way, high-output, passive, full range loudspeaker 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, 2in throat, 90°x40° coverage pattern, constant directivity horn. The CB259X requires no external active electronic crossover. [. . . ] All specifications are therefore subject to change without notice. · PUB #888119(B) May 2001 ª Printed in USA [. . . ]
