Ez I was waiting to see if you have anything more to add before I jump back in :-)
Dynamat on SIDEwalls is something I'm going to ask you about; that sounds interesting (most people just put it on the horns). However even the good old Klipsch can be harsh-sounding if you don't have them set up well, which can be difficult. You simply must have good cabling & equipment matches for the application in order to achieve good sonic results, while realizing the efficiency & dynamics of horns. It is no easy feat to pull off the right balance, so if one is not willing to work at it then you will be probably dissapointed as-above.
