• 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 medi-  
um-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  
compression 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 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 dividing the signal, performing critical equalization functions.

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.

Enclosure Materials  
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 installa-  
tion areas. HF component connection is made directly on the  
compression driver.
