PRODUCT INFORMATION
The CB423MX full-range screen channel loudspeaker system offers
small to medium-sized theaters a cost-effective entry to the future
of cinema audio – 3-way loudspeaker design. Its passive mid/high
design lets it replace existing biamped two-way systems without
requiring new electronic crossovers or amplifiers. (Electronic cross-
overs may require adjustment.)
Three-way design dramatically advances cinema audio quality by
improving the naturalness and intelligibility of dialog, eliminating
distortion from excessive driver excursion and extending pattern
control into the lower octaves.
The two component system includes a BV423 15-in low frequency
enclosure and an HK523MX mid/high section.
The low frequency enclosure uses optimally tuned enclosure venting
to increase LF response while limiting driver excursion. This method
produces less distortion and minimizes driver strain while extending
LF response to the lowest octaves. The enclosure’s shallow dimen-
sion allows convenient placement behind the screen.
The HK523MX MF/HF section features a horn-loaded 10-in cone and
a high power 1.4-in exit compression driver loaded with a 90° x
45° coverage pattern constant directivity horn.
The adjustable steel bracket attaching the mid/high section to the
LF enclosure can be positioned at one of three mounting points for
optimum front/rear placement. The bracket allows the mid/high
section to be aimed independently of the LF section in both the
horizontal and vertical planes and can be locked once it is posi-
tioned.
The HK523MX's mid and high frequency sections are integrated via
a complex passive crossover/filter network. EAW's computer-de-
signed passive filter networks are tightly aligned to the loudspeak-
ers they control and go beyond merely dividing the signal, perform-
ing critical equalization functions.
Two-terminal barrier strip input connectors that accommodate bare
wire, tinned leads or spade lugs are included for both the LF and mid/
high sections. The input panels are located on the side and top of
the enclosures for convenient access in cramped installation areas.
All external components feature a textured, non-reflective black
finish to eliminate the reflection of light through perforated cinema
screens.
