[. . . ] Locate the hole template and remove the inside portion of it. Save this part--it may be used as a paint mask. Use the inside of the template to trace the outlines at the desired location on the ceiling or wall. With a keyhole saw, cut along the penciled lines. BE CAREFUL NOT TO CUT THROUGH ANY EXISTING WIRING. Attach the speaker wires to the speaker. Be sure that proper phasing is observed. On all models, there are four clamps which hold each speaker in place. The clamps are tightened via four front-baffle screws. To install the speaker, first rotate the clamps inward. Insert the speaker into the cutout and tighten the clamps by turning the screws clockwise. Overtightening the clamps may make the grill difficult to install. NOTE: The screws will be easier to turn if you "prime" them first. Before installing each speaker, turn the screws in and then turn them back out to their original positions. The grills for Models 75 and 76 fit tightly. This is to prevent each grill from becoming loose over time. Some effort and care is required when installing them. Insert the grill into the speaker and press along the outside edge of the plastic collar. [. . . ] Fold the tape onto itself to form a double-sided loop. Affix the tape to the tweeter and place the mask onto the speaker. The grills should be painted before they are installed. For all models, the best results will be obtained by using a spray gun or airless sprayer, thinning the paint (prevents clogging of grill holes) and by applying several light coats instead of one heavy one.
