• Approved for use in THX®-certified theaters

• Tri-amplified 3-way screen channel loudspeaker
The CB523M tri-amplified three-way full-range screen channel loud-
speaker system has been approved for use in THX® certified theaters.
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 HK523M 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 dimension
allows convenient placement behind the screen.
The HK523M 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 MF/HF section to the LF
enclosure can be positioned at one of three mounting points for
optimum front/rear placement. The bracket allows the MF/HF section
to be aimed independently of the LF section in both the horizontal
and vertical planes and can be locked once it is positioned.
Input connectors for the LF and MF sections are two-terminal
barrier strips that accommodate bare wire, tinned leads or spade
lugs. Bind posts for the high frequency section are located directly
on compression driver. The input panels are located on the sides and
top of the enclosures for convenient access in cramped installation
areas.
