Cinema System CB259X Manuals







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  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.
