PRODUCT INFORMATION

The CB523M tri-amplified three-way full-range screen channel loud- speaker system has been approved for use in THX® certified theaters.

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 HK523M 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 dimension allows convenient placement behind the screen.

The HK523M 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 MF/HF section to the LF enclosure can be positioned at one of three mounting points for optimum front/rear placement. The bracket allows the MF/HF section to be aimed independently of the LF section in both the horizontal and vertical planes and can be locked once it is positioned.

Input connectors for the LF and MF sections are two-terminal barrier strips that accommodate bare wire, tinned leads or spade lugs. Bind posts for the high frequency section are located directly on compression driver. The input panels are located on the sides and top of the enclosures for convenient access in cramped installation areas.
