Storm Series Ceiling Speakers BK6C/BK8C Rough-In Bracket Figure 3.10 - Rough-In Bracket Mounting Rough-In Brackets Once the mounting locations are decided upon, assemble the brackets and secure them to the ceiling joists using fl at-head screws or heavy-duty staples (see the ATON Ceiling/In-Wall Rough-In Brackets Manual for detailed steps). Retro-Fit Retro-fi t installations are more diffi cult to complete than pre-construction because walls and ceilings are intact. Typically wires must be fi shed into position through walls, fl oors and ceilings. Holes must be cut and speakers mounted directly in the ceiling with no rough-in brackets. Note: Before cutting holes in any existing wall or ceiling surface, probe the cavity behind each speaker’s installation location for obstructions! Cutting Speaker Openings in Ceiling-No Rough-in Brackets 1. Use a stud fi nder to locate the studs around the intended speaker location. Note: A stud-fi nding device may not detect pipes, wiring, or other obstructions located behind the drywall. 2. Use the inside portion of the speaker cutout template to confi rm speaker placement. 3. Remove templates and drill or carefully punch a pilot hole in the ceiling. A bent piece of wire or a coat hanger may be use to probe the stud bay for obstructions. If you experience resistance of any kind–STOP! If any obstructions are detected, patch the pilot hole and try again in another location.

Once it has been determined that the cavity is free from obstructions, position the cutout template and use a pencil to lightly trace the perimeter of the template. 5. Cut the opening using a keyhole saw, drywall router, or razor knife. Mounting Speakers in Ceiling (Pre-Construction or Retro-Fit) 1. Remove speaker grille and place speaker face down. 2. Locate the speaker wire and pull through the ceiling opening. 3. Connect the speaker wire. BE SURE TO OBSERVE CORRECT POLARITY! 4. Insert the speaker into the opening in the ceiling (or Rough-in Bracket opening) and care- fully tighten each of the four clamping screws, alternating diagonally between each screw position to ensure proper fit. 5. Aim the pivoting tweeter at the listening area. 7. Set the Treble (A62C/A62ST/A63/A82C) and Bass (A63C) switches if applicable. See Setting Switches for details. 8. Replace the speaker grille. Figure 3.12 -Mounting Speakers In Ceiling Setting Switches Once the speakers are wired, mounted, and positioned correctly, use the Bass and Treble switches (if applicable) to fine-tune the speakers based on local environmental variables such as hardwood floors, thick draperies, etc. Select the “+” position to increase Bass/Treble response or select the “-” position if no increase or decrease is desired.
