PRODUCT INFORMATION
The CB153x full-range screen channel loudspeaker system offers small
theaters cost-effective access to the future of cinema audio – 3-way
loudspeaker design. Its full range passive design lets it be powered by
a single amplifier channel with no external electronic crossover.
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 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
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.
All sections are integrated via an internal passive crossover/filter
network. EAW's complex, computer-designed passive filter networks
are tightly aligned to the loudspeakers they control and go beyond
merely dividing the signal, performing critical equalization functions.
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 section's input plate includes a 4-terminal barrier strip which
accomodate bare wire, tinned leads or spade lugs. Two terminals serve
as inputs and the other two serve as outputs for the "jumper cable"
which connects to another 2-terminal barrier strip on the the mid/
high section. 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.
