PRELIMINARY INFORMATION
PRODUCT INFORMATION
The CB2590x passive large format 2-way stage screen loudspeaker
system fills large theaters with all the high-impact, full-range sound
encoded on today's digital soundtracks while reproducing voices
clearly and naturally.
The two component system includes a BV253C vented dual 15-in low
frequency unit and EAW's breakthrough HK2590 high frequency
system – a large format 90 x 40 curved-face horn loading a large
diaphragm 2-in exit compression driver.
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
functions.
The HK2590's curved-face horn offers several notable advantages
over traditional square large format cinema horns. In addition to
greatly improved distribution of HF information to the corners of the
coverage area and the ability to position left and right channel horns
closer to the screen, the curved face minimizes reflections of HF
information off the back of the screen which can degrade HF
performance. Further, its shortened horn throat minimizes horn
throat distortion, eliminating the 700 Hz "honk" that has plagued
cinema HF horns. The HF component (compression driver, HF horn,
bracket or mounting sled) comes completely pre-assembled from the
factory to minimize assembly time.
The BV253C's optimally vented enclosure uses enclosure resonance
to increase LF response while limiting driver excursion. This method
produces less distortion and minimizes driver strain while producing
exceptionally high output levels. Its shallow enclosure dimensions
allow convenient placement behind the screen.
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 can be aimed indepen-
dently of the LF section in both the horizontal and vertical planes
and can be locked once it is positioned.
The two-terminal barrier strip input connector creates a gas-tight
connection, minimizing corrosion and maximizing signal transfer.
The barrier strip accomodates bare wire, tinned leads or spade lugs.
A jumper cable is supplied to extend the signal chain to the HF
component. The input connector is located on the side of the
enclosure for convenient access in cramped installation areas. HF
component connection is made directly on the compression driver.
All components feature a "dead" flat black finish to eliminate the
reflection of light through perforated cinema screens.
