MTC-210UB Instructions

U-Bracket for Control SB-2210 Subwoofer Loudspeaker

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.

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.
