NOMINAL DATA
The CB153X is a compact, three-way, high-output, full range passive
loudspeaker system intended for use in behind-screen cinema appli-
cations. 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, 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 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 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.
