PRODUCT INFORMATION
The CB423M tri-amplified three-way full-range screen channel
loudspeaker system has been approved for use in THX® certi-
fied 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 BV423 15-in low fre-
quency enclosure and an HK523M passive mid/high section.
The low frequency enclosure uses optimally tuned enclosure
venting to increase LF response while limiting driver excur-
sion. 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 sec-
tion 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 side and top of the enclosures for convenient
access in cramped installation areas.
