COMPONENTS & CONSTRUCTION continued
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.
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°x45° constant directivity horn.
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.
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 perforated cinema
screens.
