Technical Specifications CB423M

COMPONENTS & CONSTRUCTION

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 system 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° 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 non-reflec- tive, textured black finish and the HF horn is constructed of flat black structural foam plastic.
