Technical Specifications CB423MX CINEMA SERIES

COMPONENTS & CONSTRUCTION

The CB423MX is a biamplified (passive mid/high) 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 HK523MX mid/high system.

The system requires the use of an external active electronic crossover between the LF and mid/high sections with a maximum recommended crossover point of 350 Hz. The mid/high component includes an internal passive crossover/filter network with the crossover set at 1.43 kHz integrated via a complex passive crossover/ filter network. EAW's computer-designed passive filter networks are tightly aligned to the loudspeakers they control and go beyond merely dividing the signal, performing critical equalization func- tions.

The BV423 low frequency component features a single 15-in woofer mounted in a vented enclosure for excellent bass extension and high output level capability.

The HK523MX 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.

Input connectors for both the LF and mid/high components are 2- terminal barrier strips that accommodate bare wire, tinned leads or spade lugs. Separate input connectors are provided for the LF and mid/high components. A pre-installed "jumper cable" continues the signal chain to the HF section.

The LF cabinet is constructed of 3/4-in Medium Density Fiberboard (MDF). The HK523MX 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 sections are coated with a non-reflective, textured black finish and the HF horn is constructed of flat black structural foam plastic.
