WARNING Calls attention to a procedure, practice, condition, or the like that, if not correctly performed or adhered to, could result in injury or death. [. . . ] Use caution to cut the hole approximately centered between wall studs, allowing at least 1 inch between the cutout and wall studs, as shown in Figure 9. Use a carpenter's level to ensure a level measurement. Baffle 1/3 of Height 1/3 of Height 1/3 of Height Place Woofer at 1/3 the height of Stud Bay 1/3 the height of Stud Bay (measured from the Fire Block) 1/3 the height of Stud Bay (measured from the Fire Block) Fire Block Figure 9: Use wall template Figure 10: Ideal Height of Woofer Figure 10: Cut wall opening Carpenter's Level Mounting Frame Figure 12: Remove Baffle From Mounting Frame 5. (Optional) It is recommended that the frame be painted before it is mounted. For instructions on painting the frame and grille, refer to page 12. The mounting frame has springloaded clamps around its perimeter, which are designed to fold shut as the mounting frame is placed into the wall opening and spring open once inside, anchoring the mounting frame in the wall opening. Loosen all clamp screws until the clamps are fully extended. 9 At least 1-inch At least 1-inch Utility Knife Figure 9: Use Wall Template Figure 11: Cut Wall Opening Figure 15: Frame Alignment Tool 7. Be sure to run the speaker wire in through the rear opening before reinstalling the baffle assembly. Insert the mounting frame into the cutout until the clamps snap into Figure place. 13: Clamp Closeup CLAMP Mounting Frame 14. Refer to the Making Connections section on page 11 for instructions.

Insert the frame alignment tool horizontally into the center of the frame. This tool functions as a frame spreader, while the clamps are being tightened, as shown in Figure 15. Starting from the lower right corner and working in a diagonal torque sequence, use a power screwdriver to tighten each of the clamp screws (only until almost snug). If needed, adjust the mounting frame so it is level and centered in the cutout. Figure 17: Tighten Allen Screws With Allen Key Wrench NOTE: Be sure that the speaker wires are clear of the woofer basket and not too close to the woofer cone. Make sure the wires are not pinched between the baffle and the mounting frame. Use the spacer shim to center the baffle inside of the frame while securing with four 10-32 x 2-1/4-inch screws. Loosely tighten the screws while using the spacer on the bottom side. Remove spacer and gauge the other three sides before starting final torque sequence. Proper centering of the baffle is critical to the grille fitting properly. Use the included 5/32-inch Allen key to tighten until snug, as shown in Figure 17. Clamp Wall B 11. Hand-tighten frame screws and check each screw at least twice to make sure they are fully tightened to prevent rattles. [. . . ] After the paint is dried, install the replacement scrim cloth, if desired. Speaker Frame Removal Attaching the Grille to the Frame To Attach the Grille: 1. Line the grille up to the frame and press the grille in only partially at first. Push gently at multiple points around the outer edges to slowly ease it into position. NOTE: Configure the four front-panel controls and experiment until optimal results are achieved, before installing the grille. [. . . ]
