• For very large theaters

• Biamplified 2-way screen channel loudspeaker

PRODUCT INFORMATION

The CB2592 large format 2-way screen channel loudspeaker system
fills the largest theaters with all the high-impact, full-range sound
encoded on today’s digital soundtracks while reproducing voices
clearly and naturally.

The three component system includes two BV253C vented dual 15­in low frequency units and EAW’s HK2591 high frequency system –
a large format 90° x 40° horn loading a large diaphragm 2-in exit
compression driver.

The HK2591's large format HF cinema horn ensures even distribution
of HF information over the entire audience area.

The BV253C’s optimally vented enclosures use enclosure resonance
to increase LF response while limiting driver excursion. This method
produces less distortion and minimizes driver strain while extending
LF response to the lowest octaves. Their shallow enclosure dimen­sions allow convenient placement behind the screen.

Each LF enclosure has 3 mounting points to allow optimum front/
rear positioning of the HF component. The adjustable mounting
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.

The LF section includes a two-terminal barrier strip that accomodates
bare wire, tinned leads or spade lugs. The HF component uses heavy
duty spring-loaded push button type connectors. Input connectors
for the LF section are located on the side of the enclosure for

convenient access in cramped installation areas. HF input connec­tors are directly on the compression driver.

All components feature a “dead” flat black finish to eliminate the
reflection of light through perforated cinema screens.

COMPONENTS & CONSTRUCTION

The CB2592 is a biamplified, high output, two-way, full range
loudspeaker system intended for use in cinema applications. It
features 4x 15-in low frequency transducers mounted in two com­pact, vented enclosures and a 2-in exit titanium diaphragm com­pression driver mounted to a large format 90° x 40° constant
directivity horn.

The CB2592 requires an external active electronic crossover. The
recommended crossover point is 500 Hz.

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. 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 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 HF component uses heavy
duty spring-loaded push button type connectors. Input connectors
for the LF sections are located on the side of the enclosure for
convenient access in cramped installation areas. HF input connec­tors are directly on the compression driver.

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.
