COMPONENTS & CONSTRUCTION
COMPONENTS & CONSTRUCTION continued
The CB259 is a biamplified, two way, high-output, full range loud-
speaker system intended for use in cinema applications. It features
dual 15-in low frequency transducers mounted in a compact, vented
enclosure and a titanium diaphragm compression driver mounted to
a large, 2-in throat, 90°x40° coverage pattern, constant directivity
horn.
The CB259 requires use of an external active electronic crossover.
The recommended crossover point is 800 Hz.
Input connectors for the HF section are dual spring loaded push but-
ton type, designed to accommodate bare or tinned leads, with a 2-
terminal barrier strip for the LF section. Separate input connectors
are provided for each section.
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, gross-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 adjustable steel HF section bracket can be locked once it is posi-
tioned.
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 allow the HF horn to be
aimed independently at the LF section in both the horizontal and
vertical planes and can be locked once it is positioned.
All components feature a textured black finish to eliminate the
reflection of light through perforated cinema screens.
