Technical Specifications CB523M
COMPONENTS & CONSTRUCTION
The CB523M is a THX-approved, triamplified three-way, high-
output, 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-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.
