APPLICATION

•For medium-sized theaters

•Bi-amplified 2-way screen channel loudspeaker

PRODUCT INFORMATION

The CB259 high power, full range two-way 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 for- mat 90°x40° HF horn loading a large diaphragm 2-in exit compres- sion driver.

The HK294’s constant directivity horn assures even distribution of high frequency information to every seat in the house. Its shortened horn throat minimizes horn throat distortion, eliminating the 700 Hz “honk” that has plagued cinema HF horns.

The BV253C’s optimally vented enclosure uses the enclosure’s reso- nance to increase LF response while limiting driver excursion. This method produces less distortion and minimizes driver strain while extending LF response to the lowest octaves.

The adjustable steel bracket attaching the HF horn to the LF enclo- sure can be positioned at one of three mounting points for optimum front/rear HF horn placement. 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 two-terminal barrier strip that accommo- dates bare wire, tinned leads or spade lugs. The Hf component uses heavy duty spring-loaded push button type connectors. input con- nectors for the LF section are located on the side of the enclosure for convenient access in cramped installation areas. HF input con- nectors are directly on the compression driver.
