• Approved for use in THX®-certified t eaters
• For medium-sized t eaters
• Tri-amplified 3-way screen c annel loudspeaker
T e CB523M tri-amplified t ree-way full-range screen c annel loud-
speaker system as been approved for use in THX® certified t eaters.
T ree-way design dramatically advances cinema audio quality by
improving t e naturalness and intelligibility of dialog, eliminating
distortion from excessive driver excursion and extending pattern
control into t e lower octaves.
T e two component system includes a BV253C dual 15-in low
frequency enclosure and an HK523M mid/ ig section.
T e low frequency enclosure uses optimally tuned enclosure venting
to increase LF response w ile limiting driver excursion. T is met od
produces less distortion and minimizes driver strain w ile extending
LF response to t e lowest octaves. T e enclosure’s s allow dimension
allows convenient placement be ind t e screen.
T e HK523M MF/HF section features a orn-loaded 10-in cone and a
ig power 1.4-in exit compression driver loaded wit a 90°x45°
coverage pattern constant directivity orn.
T e adjustable steel bracket attac ing t e MF/HF section to t e LF
enclosure can be positioned at one of t ree mounting points for
optimum front/rear placement. T e bracket allows t e MF/HF section
to be aimed independently of t e LF section in bot t e orizontal
and vertical planes and can be locked once it is positioned.
Input connectors for t e LF and MF sections are two-terminal
barrier strips t at accommodate bare wire, tinned leads or spade
lugs. Bind posts for t e ig frequency section are located directly
on compression driver. T e input panels are located on t e sides and
top of t e enclosures for convenient access in cramped installation
areas.

COMPONENTS & CONSTRUCTION continued
T e CB523M is a THX® approved, tri-amplified t ree-way, ig out-
put, full range loudspeaker system intended for use in be ind-screen
cinema applications. T e two component system includes a BV253C
dual 15-in low frequency enclosure and an HK523M mid/ ig
system.
T e system requires t e use of external active electronic crossovers
to integrate all sections.
T e BV253C low frequency component features dual 15-in woofers
mounted in a vented enclosure for excellent bass extension and ig
output level capability.
T e HK523M mid/ ig component features a orn-loaded 10-in
midrange driver and a 1.4-in exit compression driver mounted to a
medium format 90° x 45° constant directivity orn.
Two-terminal barrier strip input connectors t at accommodate bare
wire, tinned leads or spade lugs are included for t e low-and mid
frequency sections. Bind posts for t e ig frequency section are
located directly on compression driver.
T e LF cabinet is constructed of 3/4-in Medium Density Fiberboard
(MDF). T e HK523M mid/ ig section is constructed of 3/4-in MDF
wit t e exception of t e mid frequency flare w ic is void-free,
18-ply-to-t e-inc , Baltic birc plywood backed wit ig density
polyuret ane foam. Bot enclosures are coated wit a textured black
finis . T e HF orn is constructed of flat black structural foam plastic.
All external components feature a textured black finis to eliminate
t e reflection of lig t t roug perforated cinema screens.
