SERVICE NOTES
1) Remove the grille.
2) Access to the woofer and crossover network is accomplished by gently prying the woofer trim ring out of the counterbore, which is attached with a friction fit,
2) Access to the woofer and crossover network is accomplished by gently prying the woofer trim ring out of the counterbore, which is attached with a friction fit,
using a small, flat-blade screwdriver or similar tool. The four Phillips screws will then be visible.
3) Access to the HF/UHF sections is accomplished by first extracting the upper four rubber grille retainers. This can be accomplished by a) inserting a long screw
with coarse threads into the cup hole, thread the screw, and extract the cup, or b) carefully pulling them out of their cavities with long-nosed pliers or a similar
tool. It’s possible each grille cup could be damaged since the cups are affixed with RTV (silicon seal). Each cavity should be cleaned out with a 1/4" drill bit
before the Phillips head screw is turned. (Power tools are not recommended here). Remove the four screws, then pull off the faceplate with the UHF driver
attached to it.
