Suspending the Subwoofer Using Eyebolts and Shear Plates

The subwoofer can be suspended using the included eyebolts. There are three possible orientations for installing the sub-

woofer this way. 
 

1. Port facing laterally, subwoofer in “wide” orientation

 

2. Port facing laterally, subwoofer in “narrow” orientation

 

3. Port facing down

For each of these orientations, the points for eyebolt and shear plate attachment are very specific. Please consult the follow-

ing illustrations to understand each orientation and pay careful attention to which attachment points are correct.

Any unused attachment point can be used as a safety/seismic secondary attachment. Attach an eyebolt to an available at-
tachment point according to the section of the manual titled: 

Suspending the Subwoofer Using Eyebolts and 

Shear Plates

. Be sure to leave less than 12 in (300 mm) of slack in the secondary attachment cable. 

 

the safety/seismic secondary attachment must be secured to structure that is capable of supporting  

 

the weight of the subwoofer and must be connected using load rated hardware.
