Wetsounds Illusion tower brackets

Quick questions. When using the wetsounds illusion tower bracket to mount a second set of speakers where does the hole in the bracket go tower side ?? or speaker side ?? also do you still use both powder coated spacer plates like on the X mount for the top speakers or do you just use one set and replace the second set with the brackets??

Anybody ???

You only use the adapters on the bottom set. They mount with the channel to the tower so the wire runs between the tower and the bracket.

thanks got it
