Mounting the Active Speaker
Be careful when cutting the hole to mount the speaker. There is only a small amount of clearance between the
case and the mounting holes, and cutting the hole too large could compromise the stability of the speaker after
it is mounted.
Before you can mount the speaker, you must select a mounting location.
1 Trim the template and make sure it fits at the mounting location.
2 Secure the template to the mounting surface.

3 Using a 13 mm ( / in.) drill bit, drill a hole inside the corner of the line on the template to prepare the

mounting surface for cutting.
4 Using a rotary-cutting tool or jigsaw, cut the mounting surface along the inside of the dashed line on the
template.
5 Place the speaker in the cutout to test the fit.
6 If necessary, use a file and sandpaper to refine the size of the cutout.
7 After the speaker fits correctly in the cutout, ensure the mounting holes on the speaker line up with the pilot
holes on the template.
8 If the mounting holes on the speaker do not line up, mark the new pilot-hole locations.
