NOMINAL DATA
The CB423M is a THX-approved, triamplified three-way, high-
output, full range loudspeaker system intended for use in
behind-screen cinema applications. The two component sys-
tem includes a BV423 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 BV423 low frequency component features a 15-in woofer
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°x45° constant directivity
horn.
Two-terminal barrier strip input connectors that accommo-
date bare wire, tinned leads or spade lugs are included for the
low-and mid frequency sections. Bind posts for the high fre-
quency section are located directly on compression driver.
The LF cabinet is constructed of 3/4-in medium density fiber-
board (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 non-reflective, textured black finish and the
HF horn is constructed of flat black structural foam plastic.
All external components feature a non-reflective, textured
black finish to eliminate the reflection of light through per-
forated cinema screens.
