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.
