It looks like I’ll need to have my foam panels freestanding at my first reflection points due to some obstacles. Also, if I put a panel 90 degrees to my listening position on my right side, I’ll have no wall behind it. My questions are: do I need a backing board to the panels so I get some reflection back or just let the sound go through – especially on the one with no wall behind? Does a freestanding panel need thicker foam than 2”? Thanks.
