•Bi-amplified 3-way screen channel loudspeaker

PRODUCT INFORMATION

The CB523MX full-range screen channel loudspeaker system offers medium-sized theaters a cost-effective entry to the future of cinema audio - three way loudspeaker design. Its passive mid/high design lets it replace existing bi-amped two-way systems without requiring new electronic crossovers or amplifiers. (Electronic crossovers may require adjustment.)

Three-way design dramatically advances cinema audio quality by improving the naturalness and intelligibility of dialog, eliminating distortion from excessive driver excursion and extending pattern control into the lower octaves.

The two component system includes a BV253C dual 15-in low frequency enclosure and an HK523MX mid/high section.

The low frequency enclosure uses optimally tuned enclosure venting 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. The enclosure’s shallow dimen- sion allows convenient placement behind the screen.

The HK523MX MF/HF section features a horn-loaded 10-in cone and a high power 1.4-in exit compression driver loaded with a 90°x45° coverage pattern constant directivity horn.

The adjustable steel bracket attaching the mid/high section to the LF enclosure can be positioned at one of three mounting points for optimum front/rear placement. The bracket allows the mid/high section to be aimed independently of the LF section in both the hor- izontal and vertical planes and can be locked once it is positioned.

The HK523MX’s mid and high frequency sections are integrated via a complex passive crossover/filter network. EAW’s computer-designed passive filter networks are tightly aligned to the loudspeakers they control and go beyond merely dividing the signal, performing critical equalization functions.

Two-terminal barrier strip input connectors that accommodate bare wire, tinned leads or spade lugs are included for both the LF and mid/high sections. The input panels are located on the sides and top of the enclosures for convenient access in cramped installation areas.
