PRODUCT INFORMATION
The CB153 full-range screen channel loudspeaker system offers small
theaters cost-effective access to the future of cinema audio – 3-way
loudspeaker design. Its passive mid/high biamplified design lets it
replace existing biamped 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 WGP®
waveguide.
The BV154C’s optimally vented enclosure uses the enclosure's
resonance 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
component'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
bracket attaching the mid/high component to the LF enclosure
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 positioned.
The LF and MF/HF sections include 2-terminal barrier strips which
accomodate bare wire, tinned leads or spade lugs. The input panels
are located on the sides of the enclosures for convenient access in
cramped installation areas.
All external components feature a textured black finish to eliminate
the reflection of light through perforated cinema screens.
