Installation Instructions
• Make sure that the wall surface is strong enough to support the
total weight of the speaker and the U bracket. Avoid attaching the
U bracket to drywall, such as acoustic tiles.
• Secure the speaker to the mounting structure with a properly
rated safety wire.
Vertical installation
1 Assemble two L-shaped brackets into a U-shape using
the included M5x10 screws as shown in the figure below.
Peel off the sheet from each rubber spacer, and then
attach the spacers to the inside of each bracket arm by
aligning the holes so that the hexagon bolts can be
inserted.
2 Make sure that the width of the U bracket matches the
speaker width.
3 Affix the U bracket on the wall or ceiling using
appropriate metal brackets and bolts.
These metal brackets or bolts are not included in the
package. If you are not sure what to use to affix the U
bracket, consult a specialist.
4 Use the included M8x25 hexagon bolts, spring washers,
and flat washers to attach the speaker to the U bracket.
UB-DXR15 / UB-DXR12
Use the bolt hole in the center of the handle on each
side of the speaker.
UB-DXR10 / UB-DXR8

5 Adjust the speaker angle, then tighten the bolts until the
speaker is securely affixed.
