Technical Specifications CB153x

COMPONENTS & CONSTRUCTION

The CB153x is a compact, three-way, high-output, full range passive loudspeaker system intended for use in behind-screen cinema applications. The two component system consists of a BV154C low frequency enclosure and an HK153 passive mid/high system.

The system can be powered by a single amplifier channel and requires no external electronic crossovers. EAW's complex, com- puter-designed passive filter networks are tightly aligned to the loudspeakers they control and go beyond merely dividing the signal, performing critical equalization functions.

The BV154C low frequency component features a single 15-in low frequency driver mounted in an asymmetrical, vented enclosure for excellent bass extension and high output level capability with low distortion.

The HK153 mid/high component features a 1-in exit compression driver loaded with EAW’s proprietary WGP® (Wave Guide Plate) and a direct radiating 8-in mid frequency cone transducer.

The LF cabinet is constructed of 3/4-in Medium Density Fiberboard (MDF) with the exception of the baffle, which is constructed of 15mm void-free, 18-ply-to-the-inch Baltic birch plywood. The mid/ high enclosure is constructed entirely of the MDF. Extensive internal bracing is provided for both the LF and mid/high sections to minimize panel resonances resulting from the large acoustical energies generated within the enclosure while maximizing acousti- cal energy transfer into the audience area. The enclosures and all external parts are coated with a textured black finish.

The LF section's input plate includes a 4-terminal barrier strip which accomodate bare wire, tinned leads or spade lugs. Two terminals serve as inputs and the other two serve as outputs for the "jumper cable" which connects to another 2-terminal barrier strip on the the mid/high section. The input panels are located on the sides of the enclosures for convenient access in cramped installation areas.

The adjustable steel bracket attaching the mid/high component to the LF enclosure allows the mid/high section to be aimed indepen- dently of the LF section in both the horizontal and vertical planes and can be locked once it is positioned. The LF enclosure has 2 mounting points to allow optimum front/rear positioning of the mid/high component.
