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  
a complex 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.
