You may get the desired result just pulling the speakers out an inch or two especially if you are plugging the ports. Also another possibility is to close off those cabinet spaces so they are flush with the wall and installing M22 on wall speakers. That would remove the issue of any sound reverberating inside of the cabinet cavity. Since you are all subbed up with the 500 the on walls would probably do very nicely.

It all matters.....just not very much.
