Note

  In order to prevent the unit from falling down, attach the safety wire as 

shown in the illustration.

 CAUTION

•  Before doing any installation or construction work, consult with your Yamaha dealer.
•  For optimum safety, the installation should be checked thoroughly at regular intervals. Some fittings may deteriorate 

over extended periods of time due to wear and/or corrosion.

•  When choosing the installation location, suspension wire and mounting hardware, make sure all are strong enough to 

support the weight of the speaker.

•  Make sure to take measures to prevent the speaker from falling down in the event of a installation failure.
•  When installing the safety wire to the wall, install it higher than the wire’s attachment 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 using eye bolts

Attach commercially-available eye bolts (M8 x 15 mm) to the screw holes located at the bottom (two locations) 
and on the upper rear (one location, only for DBR15 and DBR12). Keep in mind that you will need two points 
at the bottom to suspend the unit.
