• For small theaters
• Bi-amplified 3-way screen channel loudspeaker
The CB153 full-range screen channel loudspeaker system offers
small theaters cost-effective access to the future of cinema audio threeway loudspeaker design. Its passive mid/high bi-amplified
design lets it replace existing bi-amped 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 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 Wave
Guide Plate (WGP™).
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
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 be 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
accommodate 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.

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 recommended 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 2terminal 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 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.
All external components feature a textured black finish to eliminate
the reflection of light through perforated cinema screens
