The CB153 is a ompa t, bi-amplified (passive mid/high), three-way,
high-output, full range loudspeaker system intended for use in
behind-s reen inema appli ations. The two omponent system
onsists of a BV154C low frequen y en losure and an HK153 passive
mid/high system.
The system requires the use of an external a tive ele troni rossover
between the LF and mid/high se tions with a maximum re ommend-
ed rossover point of 350 Hz. The mid/high omponent in ludes a
internal passive rossover/filter network with the rossover set at
1.8 kHz. EAW’s omplex, omputer-designed passive filter networks
are tightly aligned to the loudspeakers they ontrol and go beyond
merely dividing the signal, performing riti al equalization
fun tions.
The BV154C low frequen y omponent features a single 15-in low
frequen y driver mounted in an asymmetri al, vented en losure for
ex ellent bass extension and high output level apability with low
distortion.
The HK153 mid/high omponent features a 1-in exit ompression
driver loaded with EAW’s proprietary WGP® (Wave Guide Plate) and a
dire t radiating 8-in mid frequen y one transdu er.
The LF abinet is onstru ted of 3/4-in Medium Density Fiberboard
(MDF). The mid/high en losure is onstru ted entirely of the MDF.
Extensive internal bra ing is provided for both the LF and mid/high
se tions to minimize panel resonan es resulting from the large
a ousti al energies generated within the en losure while maximizing
a ousti al energy transfer into the audien e area. The en losures and
all external parts are oated with a textured bla k finish.
Input onne tors for both the LF and mid/high se tions are 2-
terminal barrier strips. Separate input onne tors for the LF and
mid/high se tions are lo ated on the side of the en losure for
onvenient a ess in ramped installations areas.
The adjustable steel bra ket atta hing the mid/high omponent to
the LF en losure allows the mid/high se tion to be aimed independ-
ently of the LF se tion in both the horizontal and verti al planes and
an be lo ked on e it is positioned. The LF en losure has 2 mount-
ing points to allow optimum front/rear positioning of the mid/high
omponent.
All external omponents feature a textured bla k finish to eliminate
the refle tion of light through perforated inema s reens
