I am considering purchasing this speaker to use on a 7.1.4 configuration. I am looking to ceiling mounting them horizontally but am concerned about the weight of the speaker hanging done using the threaded inserts that are off center.

I would prefer not to screw screws into the back.

Is it possible to order these speakers with an additional set of inserts on the opposite side so there are 4 inserts equally spaced?

TIA
