The MTC-29UB bracket mounts for the control 29AV loudspeaker to the walls, decks and ceilings and provides a degree of swiveling capability. Read and follow these instructions carefully before beginning. Installing speakers must be performed by experienced professionals. 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. Select the mounting area where the speaker be positioned. Be sure there is adequate structural material for mounting, such as a stud. 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. Rotate the speaker until it is aimed in the desired direction, then secure the side bolts permanently with a wrench.
