PRODUCT INFORMATION
The CB150 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 HK200 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 HK200 features a 7-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 driver 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 “dead” flat black finish to
eliminate the reflection of light through perforated cinema screens.

COMPONENTS & CONSTRUCTION
The CB150 is a compact, biamplified (passive mid/high), three-way,
high-output, full range loudspeaker system intended for use in
behind-screen cinema applications. The two component system
consists of a BV154C low frequency enclosure and an HK200 passive
mid/high system.
The system requires the use of an external active electronic
crossover between the LF and mid/high sections with a maximum
recommended crossover point of 350 Hz. The mid/high component
includes a internal passive crossover/filter network with the cross-
over set at 1.8 kHz. 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 HK200 mid/high component features a 1-in exit compression
driver loaded with EAW’s proprietary WGP® (Wave Guide Plate) and
a direct radiating 7-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 acousti-
cal energy transfer into the audience area. The enclosures and all
external parts are coated with a flat black finish.
Input connectors for both the LF and mid/high sections are 2-
terminal barrier strips. Separate input connectors for the LF and
mid/high sections are located on the side of the enclosure 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 indepen-
dently 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.
