CAUTION
• Make sure that the installation surface is strong enough to support the total weight of the speaker and the U-bracket. If you
are not sure about the installation surface, consult a specialist. Avoid attaching the U-bracket to drywall such as acoustic
tiles.
• Make sure to take precautionary measures using wires to prevent the speaker
from falling down in the event of an installation failure. Attach commercially-avail-
able M8 eye bolts to the screw holes for the U-bracket, and attach M8 for DXR10 or
M10 for DHR10/CHR10 to the screw holes (rigging points) located at the top (two
locations) and on the lower rear (one location) of those units. For the DHR10 and
CHR10, use eye bolts 30–50 mm in length.
• When installing the safety wire to the wall, install it higher than the wire’s attach-
ment point on the speaker, with as little slack as possible. If the wire is too long,
and the speaker happens to fall, the wire may snap as a result of too much strain.
Yamaha cannot be held responsible for damage or injury caused by insufficient strength of the support structure or
improper installation.

Installation Instructions
Vertical installation
1. Assemble two L-shaped brackets into a U-shape using
the included M5 × 10 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 appropri-
ate 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 hexagon bolts (M8×25 for DXR10,
M8×55 for DHR10 and CHR10), M8 spring washers, and
M8 flat washers to attach the speaker to the U-bracket.
The mounting position of the speaker is sealed before
shipment, so remove the seal for DXR10, and remove the
M8 screws (2 total) for DHR10 and CHR10 with a 5 mm
hexagon wrench in advance.

5. Adjust the speaker angle, then tighten the bolts until the
speaker is securely affixed. The recommended torque is
12.4 Nm.
CAUTION
Make sure that you do not pinch your fingers
between the U-bracket and speaker.
(DHR10, CHR10 only) Carefully store the screws removed from the
speaker so that they are not lost. Using the speaker with the screws
removed will negatively affect sound quality due to air leakage
because the screw holes penetrate the inside of the speaker cabi-
net. Re-install the screws to the original screw holes after removing
the U-bracket.
