Read and follow these instructions carefully before beginning.
Installing speakers must be performed by experienced professionals. If you have any doubts about the integrity of the structure you are mounting to or are not sure about the proper hardware or method to use, consult a structural engineer.
Qty – Description
1 pc. – Bracket
2 pcs – Friction Gasket
2 pcs – Bolt, 6mm, 1mm pitch, 20 mm long,18-8SS
2 pcs – Fender Flat Washers for 6mm,18-8SS
2 pcs – Spring Lock Washer for 6mm,18-8SS
Step 1 Test Fit the Bracket to the Speaker Place the bracket over the speaker cabinet. Gaps between the speaker surface and the bracket arms are to be filled in with the included friction gasket. Test the included hardware to make sure the bolts, washers and lock washers fit correctly. Determine which slot you will be using and how the bracket will be positioned in relation to the speaker. Determine which threaded hole in the speaker will be used (Note: The center hole is closest to the center of gravity, so the speaker will stay in position best when using the center hole.) Make sure you will have enough wall clearance for your intended positioning. Remove the bracket from the speaker.
Step 2 Install the Bracket Securely to Building Structure Select the mounting area where the speaker will be positioned. Be sure there is adequate structural material for mounting, such as a stud. Do not rely on drywall, acoustic tiles, etc. to support the weight of the speaker. Follow building code requirements to safely install the bracket to the building structure. Tighten all hardware permanently.
Step 3 Install Speaker into Bracket. Position the speaker in between the bracket arms and install the included hardware through the desired slots and into the speaker cabinet’s threaded holes. Be sure to place the friction gaskets between the speaker and the bracket arms then tighten the bolts loosely, not tight.
Step 4 Aim the Speaker Rotate the speaker until it is aimed in the desired direction, then secure the side bolts permanently with a wrench.
Step 5 Recommendation: Safety Cable It is strongly recommended that the speaker be secured to the mounting structure with a properly rated safety cable.
