*VERY IMPORTANT*
Please note that the pivoting lock arms are not designed to support
the weight of the speaker. They are only designed to pull the speaker
tight to the ceiling and prevent it from rattling. Do not use them for
supporting the speaker. The screws going through the speaker and
into the joists are there for support and must be properly used.
