COMPONENTS & CONSTRUCTION
COMPONENTS & CONSTRUCTION continued
The CB153 is a compact, bi-amplified (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 HK153 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 recommend-
ed crossover point of 350 Hz. The mid/high component includes a
internal passive crossover/filter network with the crossover 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 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). 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.
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 installations areas.
The adjustable steel bracket attaching the mid/high component to
the LF enclosure allows the mid/high section to be aimed independ-
ently of the LF section in both the horizontal and vertical planes and
can be locked once it is positioned. The LF enclosure has 2 mount-
ing points to allow optimum front/rear positioning of the mid/high
component.
All external components feature a textured black finish to eliminate
the reflection of light through perforated cinema screens
