IMPORTANT:

This product must be installed in accordance with your local area’s building 

codes and regulations.  This may require use of an additional support bracket, 

depending on the installation.  In this case, use the MBR-70 described below.

SEISMIC TAB:

For proper installation, the seismic tab MUST be secured to a secondary 

support in the event of failure of the primary support structure.

MBR-70: 

(sold separately)

The MBR-70 consists of a round bracket and two rails designed to be used 

with suspension ceilings.  The rails will fit either 24” or 600

mm

 tiles.  They are 

designed to rest on top of the tile without the “V” end of the rail grabbing the 

grid struts.  In the event that the tile falls, the “V” end of the rail will grab the 

strut holding the speaker in place.  The MBR-70 is not required for installation 

when the speaker is being installed in drywall or other rigid material.  When 

installing in these surfaces, use attached swivel mounts and hole locating 

template included in the box with each loudspeaker.

For  suspension  ceiling  installation  instructions,  refer  to  the  installation 

manual included with the MBR-70.
