Technical Specifications CB259x
COMPONENTS & CONSTRUCTION
The CB259x is a two way, high-output, passive, full range loud-
speaker system intended for use in cinema applications. It features
dual 15-in low frequency transducers mounted in a vented enclosure
and a titanium diaphragm compression driver mounted to a large, 2-
in throat, 90
°
x 40
°
coverage pattern, constant directivity horn.
The CB259x requires no external active electronic crossover. An
internal passive crossover/filter network integrates the LF and HF
sections. 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 func-
tions.
The input connector is a 2-terminal barrier strip located on the side
of the LF section for convenient access in cramped installation
areas. A jumper cable is provided to extend the signal chain to the
HF component.
The low frequency enclosure is constructed of 3/4-in thick Medium
Density Fiberboard (MDF) with the exception of the baffle which is
15-mm void-free, cross-grain-laminated birch plywood. Extensive
internal bracing is employed to minimize panel resonances resulting
from the large acoustical energies generated within the enclosures.
The high frequency horn is constructed from a specially formulated
compound which is non-resonant, lightweight and non-reflective.
The LF enclosure has 3 mounting points to allow optimum front/rear
positioning of the HF component. The adjustable steel bracket
attaching the HF horn to the LF enclosure allows the HF horn to be
aimed independently of the LF section in both the horizontal and
vertical planes and can be locked once it is positioned.
