• For small theaters
• Bi-amplified 3-way screen channel loudspeaker
The CB153 full-range screen channel loudspeaker system offers
small theaters cost-effective access to the future of cinema audio -
threeway loudspeaker design. Its passive mid/high bi-amplified
design lets it replace existing bi-amped two-way systems without
requiring new electronic crossovers or amplifiers. (Electronic
crossovers settings may need to be adjusted.)
The two component system consists of a BV154C low frequency
enclosure and an HK153 passive mid/high system.
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 HK153 features an 8-in MF cone transducer and a 1-in exit high
frequency compression driver loaded with EAW’s patented Wave
Guide Plate (WGP™).
The BV154C’s optimally vented enclosure uses the enclosure’s reso-
nance to increase LF response while limiting the single 15-in cone
transducer’s excursion. This method produces less distortion and
minimizes driver strain while extending LF response to the lowest
octaves.
Its asymmetrical enclosure design smooths response in the LF com-
ponent’s upper register and minimizes the potential for standing
waves inside the enclosure. Left and right side enclosures can be
placed flush to a back wall while still focusing their output to the
audience area. The enclosure can be inverted to provide a right or
left-handed angle.
The LF enclosure has 2 mounting points to allow optimum front/rear
positioning of the mid/high component. The adjustable steel brack-
et attaching the mid/high component to the LF enclosure allows the
mid/high section be be aimed independently of the LF section in
both the horizontal and vertical planes and can be locked once it is
positioned.
The LF and MF/HF sections include 2-terminal barrier strips which
accommodate bare wire, tinned leads or spade lugs. The input pan-
els are located on the sides of the enclosures for convenient access
in cramped installation areas.
