• For medium-sized theaters
• Bi-amplified 3-way screen channel loudspeaker
The CB523MX full-range screen channel loudspeaker system offers
medium-sized theaters a cost-effective entry to the future of
cinema audio - three way loudspeaker design. Its passive mid/high
design lets it replace existing bi-amped two-way systems without
requiring new electronic crossovers or amplifiers. (Electronic
crossovers 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 BV253C dual 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°x45°
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 hor-
izontal and vertical planes and can be locked once it is positioned.
The HK523MX’s mid and high frequency sections are 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.
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 sides and top
of the enclosures for convenient access in cramped installation
areas.
