APPLICATION

• For small theaters

• Full range passive 3-way screen channel loudspeaker

• Requires no external electronic crossover

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.

INPUT

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 left­handed 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.

COMPONENTS & CONSTRUCTION

The CB153x is a compact, three-way, high-output, full range passive
loudspeaker system intended for use in behind-screen cinema
applications. The two component system consists of a BV154C low
frequency enclosure and an HK153 passive mid/high system.

The system can be powered by a single amplifier channel and
requires no external electronic crossovers. 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 BV154C low frequency component features a single 15-in low
frequency driver mounted in an asymmetrical, vented enclosure for
excellent bass extension and high output level capability with low
distortion.

The HK153 mid/high component features a 1-in exit compression
driver loaded with EAW’s proprietary WGP® (Wave Guide Plate) and
a direct radiating 8-in mid frequency cone transducer.

The LF cabinet is constructed of 3/4-in Medium Density Fiberboard
(MDF) with the exception of the baffle, which is constructed of
15mm void-free, 18-ply-to-the-inch Baltic birch plywood. The mid/
high enclosure is constructed entirely of the MDF. Extensive internal
bracing is provided for both the LF and mid/high sections to
minimize panel resonances resulting from the large acoustical
energies generated within the enclosure while maximizing acousti­cal energy transfer into the audience area. The enclosures and all
external parts are coated with a textured black finish.

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.

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 enclosure has 2
mounting points to allow optimum front/rear positioning of the
mid/high component.
