I was messing with some UltraRes cabs in parallel and I ran into this so I thought I would share.
I added the second cab (the same cab and in my cab 1) and I was getting a hollowed out sound consistent with a phase issue.
I managed to track it down to one cab having motor drive on and the other with none. You can hear it right away when one motor drive is set to something other than zero and the other is set to zero.
It is something to be aware of if things do not sound right between two cabs in parallel.
