Carefully move the cables back inside the cabinet while moving the tweeter chassis toward its recessed location.

While supporting the chassis with your one hand while it's in place, insert the upper screw and screw it in lightly to fix the component in its correct position.

Insert both lower screws and screw them in lightly with your fingers.

Finally, use your Hex wrench hand tool and tighten all three screws finger tight until the component is securely locked in its place. Make sure not to overtighten the screws.
