COMPONENTS & CONSTRUCTION
The CB2590x is a two-way, high output, full range loudspeaker
system intended for use in cinema applications. It features dual 15-
in low frequency transducers mounted in a compact, vented enclo-
sure and a 2-in exit titanium diaphragm compression driver mounted
to a large format 90
°
x 40
°
constant directivity horn.
The CB2590x requires no external active electronic crossover. The
subsystems 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 func-
tions.
The low frequency enclosure is constructed of 3/4-in thick Medium
Density Fiberboard with the exception of the baffle which is 15mm
void-free, cross-grain-laminated Baltic birch plywood. Extensive
internal bracing is employed to minimize panel resonances resulting
from the large acoustical energies generated within the enclosures.
The enclosure and all external parts are coated with a flat black
polyurethane finish.
The high frequency horn is constructed from a specially formulated
urethane compound which is non-resonant, lightweight and non-
reflective.
Input connector is a 2-terminal barrier strip located on the side of
the LF section for convenient access in cramped installation areas.
The barrier strip accomodates bare wire, tinned leads or spade lugs.
A jumper cable is provided to extend the signal chain to the HF
component.
The LF enclosure has 3 mounting points to allow optimum front/rear
positioning of the HF component. The adjustable mounting sled
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. The HF
component (compression driver, HF horn, bracket or mounting sled)
comes completely pre-assembled from the factory to minimize
assembly time.
