PRODUCT INFORMATION

The CB423MX full-range screen channel loudspeaker system offers small to medium-sized theaters a cost-effective entry to the future of cinema audio – 3-way loudspeaker design. Its passive mid/high design lets it replace existing biamped two-way systems without requiring new electronic crossovers or amplifiers. (Electronic cross- overs 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 BV423 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° x 45° 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 horizontal and vertical planes and can be locked once it is posi- tioned.

The HK523MX's mid and high frequency sections are integrated via

acomplex passive crossover/filter network. EAW's computer-de- signed passive filter networks are tightly aligned to the loudspeak- ers they control and go beyond merely dividing the signal, perform- ing 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 side and top of the enclosures for convenient access in cramped installation areas.

All external components feature a textured, non-reflective black finish to eliminate the reflection of light through perforated cinema screens.
