Technical Specifications CB423MX
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.
