COMPONENTS & CONSTRUCTION continued
The CB523M is a THX® approved, tri-amplified three-way, high out-
put, full range loudspeaker system intended for use in behind-screen
cinema applications. The two component system includes a BV253C
dual 15-in low frequency enclosure and an HK523M mid/high
system.
The system requires the use of external active electronic crossovers
to integrate all sections.
The BV253C low frequency component features dual 15-in woofers
mounted in a vented enclosure for excellent bass extension and high
output level capability.
The HK523M mid/high component features a horn-loaded 10-in
midrange driver and a 1.4-in exit compression driver mounted to a
medium format 90° x 45° constant directivity horn.
Two-terminal barrier strip input connectors that accommodate bare
wire, tinned leads or spade lugs are included for the low-and mid
frequency sections. Bind posts for the high frequency section are
located directly on compression driver.
The LF cabinet is constructed of 3/4-in Medium Density Fiberboard
(MDF). The HK523M mid/high section is constructed of 3/4-in MDF
with the exception of the mid frequency flare which is void-free,
18-ply-to-the-inch, Baltic birch plywood backed with high density
polyurethane foam. Both enclosures are coated with a textured black
finish. The HF horn is constructed of flat black structural foam plastic.
All external components feature a textured black finish to eliminate
the reflection of light through perforated cinema screens.
