PRODUCT INFORMATION
The CB150x full-range passive stage/screen loudspeaker system
offers small cinemas cost-effective access to the future of cinema
audio – 3-way loudspeaker design. Its passive design lets it replace
existing two-way systems powered by a single amplifier channel
without requiring new processors or amplifiers.
The two component system consists of a BV153C low frequency
enclosure and an HK200 passive mid/high system integrated via a
passive crossover/filter network. EAW's complex, computer-de-
signed passive filter networks are tightly aligned to the loudspeak-
ers they control and go beyond merely dividing the signal, perform-
ing critical equalization functions.
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 CB150x’s passive mid/high component – the HK200 – features
a dedicated midrange frequency subsystem that solves many of
cinema audio’s long standing problems. Moving crossover points out
of the vocal region eliminates the acoustical anomalies which
degrade the naturalness and intelligibility of dialog. Its direct
radiating 7-in MF cone transducer eliminates the horn-throat
cancellation distortion typical of two-way cinema loudspeakers. And
by loading the 1-in exit high frequency compression driver with
EAW’s patented WGP® waveguide, HF information is distributed
evenly over the entire audience area.
The BV153C low frequency subsystem uses optimally tuned enclosure
venting 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. The enclosure’s shallow
dimension allow convenient placement behind the screen.
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 2-terminal barrier strip input connector creates a gas-free
connection to minimize corrosion and maximize signal transfer. A
jumper cable is provided to extend the signal chain to the mid/high
component. The input panel is located on the side of the enclosure
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 CB150x is a compact, passive, three-way, high-output, full
range loudspeaker system intended for use in behind-screen cinema
applications. The two component system consists of a BV153C low
frequency enclosure and an HK200 passive mid/high system.
The system requires no external active electronic crossover. An
internal passive crossover/filter network integrates all subsystems.
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 func-
tions.
The BV153C low frequency component features a single 15-in low
frequency driver mounted in a slim, vented enclosure for excellent
bass extension and high output level capability.
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 cone transducer covering the entire vocal
range.
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 same MDF. Extensive
internal bracing is provided for both the LF and mid/high sections.
The enclosures and all external parts are coated with a flat black
polyurethane finish.
The input connector is a 2-terminal barrier strip located on the side
of the LF enclosure for convenient access in cramped installation
areas. A jumper cable is provided to extend the signal chain to 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 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.
