• For small theaters
• Full range passive 3-way screen channel loudspeaker
• Requires no external electronic crossover
The CB153X full-range screen channel loudspeaker system offers
small theaters cost-effective access to the future of cinema audio three-way loudspeaker design. Its full range passive design lets it be
powered by a single amplifier channel with no external electronic
crossover.
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.
All sections are integrated via an internal passive crossover/filter
network 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 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 section’s input plate includes a 4-terminal barrier strip which
accommodate bare wire, tinned leads or spade lugs. Two terminals
serve as inputs and the other two serve as outputs for the “jumper
cable” which connects to another 2-terminal barrier strip on the
mid/high section. The input panels are located on the sides of the
enclosures for convenient access in cramped installation areas.

NOMINAL DATA
The CB153X is a compact, three-way, high-output, full range passive
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 can be powered by a single amplifier channel and
requires no external electronic crossovers. EAW’s complex, computerdesigned 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 Wave Guide Plate (WGP™) and
a direct radiating 8-in mid frequency cone transducer.
Both sections are constructed of 3/4-in Medium Density Fiberboard
(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.
The LF section’s input plate includes a 4-terminal barrier strip which
accommodate bare wire, tinned leads or spade lugs. Two terminals
serve as inputs and the other two serve as outputs for the “jumper
cable” which connects to another 2-terminal barrier strip on the
mid/high section. The input panels are located on the sides of the
enclosures 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 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.
