TECHNICAL SPECIFICATIONS CB523M

COMPONENTS & CONSTRUCTION

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.
