Looks much better. Flipping the phase switch might help with that dip at 75-80 hz, as John suggested further up the thread. If you have already flipped the switch, flip it back

Do you have room dimensions around 11 and 19 feet ? That's what the first two peaks seem to indicate.

The 135 hz dip seems to relate to having the fronts of your speakers a bit over two feet from the wall. Make sure you don't have similar distances from front of M80 to both back and side wall -- if you do, make 'em different if possible. The changes John suggested for sub placement would probably also help that 135 Hz dip.

Note that putting the sub in the middle of a wall can significantly reduce the bass spike that you get from the room mode corresponding to that dimension, ie "nasty peak at a frequency 565/room dimension" => "try sub in middle of that wall".
