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

Use the bolt hole on each side of the speaker.

5 Adjust the speaker angle, then tighten the bolts until the

speaker is securely affixed.
