Setup and Installation

The JBL Stage 280C is designed for easy installation in ceilings or walls. Ensure you have the necessary tools before beginning.

Tools Required:

• Pencil
• Drywall Saw or Rotary Tool
• Wire Strippers
• Screwdriver (Phillips head)
• Measuring Tape
• Safety Glasses and Gloves

Installation Steps:

1. Plan Placement: Determine the optimal location for your speaker, ensuring there are no obstructions (e.g., studs, wiring, plumbing) behind the drywall.
2. Cut Opening: Use the provided installation template to trace the cutout hole on the ceiling or wall. Carefully cut the opening using a drywall saw or rotary tool.
3. Run Speaker Wire: Route speaker wire (minimum 16-gauge recommended) from your amplifier or receiver to the cutout opening. Leave enough slack for connection.
4. Connect Speaker Wires: Strip approximately 1/2 inch (12mm) of insulation from the ends of the speaker wires. Connect the positive (+) terminal of the speaker to the positive (+) terminal of your amplifier, and the negative (-) terminal of the speaker to the negative (-) terminal of your amplifier. The JBL Stage 280C uses spring-loaded connectors.
5. Insert Speaker: Carefully insert the speaker into the cutout opening.
6. Secure Speaker: The speaker features an XL-2 Installation System. Tighten the mounting screws on the front baffle of the speaker. This will rotate the dog-leg clamps outwards and secure the speaker firmly to the drywall. Do not overtighten. The system is compatible with wall/ceiling material up to 2 inches thick.
7. Attach Grille: The zero-bezel grille is magnetic. Simply align it with the speaker frame and it will snap into place. The grille is paintable to match your room's decor.
