Input connectors for both the LF and mid/high components are 2- terminal barrier strips the accommodate bare wire, tinned leads or spade lugs. 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.

All external components feature a non-reflective, textured black finish to eliminate the reflection of light through perforated cinema screens.

COMPONENTS & CONSTRUCTION

The CB523MX is a bi-amplified (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 BV253C dual 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 1.8 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 functions.

The BV253C low frequency component features dual 15-in woofers mounted in a vented enclosure for excellent bass extension and high output level capability.
