UMS-SM Dimensions with U-Bracket
The UMS-SM subwoofer is a version of the UMS-1P sub-
woofer with threaded end plates for single-mount configura-
tions with the UMS-SM U-bracket. The UMS-SM end plates
are factory-installed (with the U-bracket) and not available
as an upgrade option for the UMS-1P. The UMS-SM retains
the same acoustical and electrical characteristics of the
UMS-1P.
NOTE: For complete information on the electri-
cal and acoustical characteristics of the
UMS-SM, refer to the UMS-1P Operating Instruc-
tions.
Important Safety Considerations for Rigging!
When installing Meyer Sound loudspeakers, the following
precautions should always be observed:
■
All Meyer Sound products must be used in accordance
with local, state, federal, and industry regulations. It is
the owner’s and user’s responsibility to evaluate the reli-
ability of any rigging method for their application. Rigging
should only be carried out by experienced professionals.
■
■
Use mounting and rigging hardware that has been rated
to meet or exceed the weight being hung.
Make sure to attach mounting hardware to the building's
structural components (studs or joists), and not just to
the wall surface. Verify that the building's structure and
the anchors used for the installation will safely support
the total weight of the mounted loudspeakers.
■
Use mounting hardware appropriate for the surface
where the loudspeaker will be installed.
