COMPONENTS & CONSTRUCTION
The CB2591x is a high output, passive, two-way, full range loud-
speaker system intended for use in behind screen cinema applica-
tions. It features dual 15-in low frequency transducers mounted in
a compact, vented enclosure and a 2-in exit titanium diaphragm
compression driver mounted to a large format 90° x 40° constant
directivity horn.
The CB2591x requires no external active electronic crossover. The HF
and LF sections 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 diving the signal, performing critical equalization
functions.
The low frequency enclosure is constructed of 3/4-in thick Medium
Density Fiberboard (MDF) with the exception of the baffle which is
15mm void-free, cross-grain-laminated Baltic birch plywood. Exten-
sive 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 dampened
fiberglass which is non-resonant, lightweight and non-reflective.
The LF section includes a two-terminal barrier strip that accomodates
bare wire, tinned leads or spade lugs. The input panel is located on
the side of the LF enclosure for convenient access in cramped
installation areas. A jumper cable is provided to extend the signal
chain to the HF component.
The adjustable mounting bracket attaching the HF horn to the LF
enclosure can be positioned at one of three mounting points for
optimum HF horn placement. It 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.
