You can still use both inputs, that won't matter.
Dikki, I've been in a couple situations where there was an overhang, design in the ceiling, or slope where I had to reposition the tower, or where it was a tight fit.
One instance was in the lounge of the American Legion where we had the Jam (but not the room we used this time). I had to put the two sections together then slide the system back under the overhang to get it where I wanted.
It's pretty rare, but it does happen.
Personally, I would rather be out of position than to use half of the tower. You can hear it anywhere it is, but it's optimal when it's just behind and slightly to the side.
