I don't but I do have some experience with some of the larger Klipsch stuff.
If that works for you, then fantastic!!
If you still find it wanting a bit, have you thought about looking at some of their larger offerings?
I'm thinking, beater Cornwall, beater LaScala (preferable with handles), maybe something out of their cinema lineup...
I bought a pair of MWM bass bins. These are the monsters that are 8 (yes eight) feet wide. I paid $250 for them and the only issue was, I didn't have the midhorn/tweeter to go with them.
For my specific circumstance, that was ok as I had other solutions by Klipsch that would work wonderfully.
I realize it's a bit of a nuts-o suggestion so I'm not expecting you to take it seriously. All I'm hoping to do is perhaps shake your thinking into getting outside the traditional box of logic and realize there are other options out there that might be cost effective.
My brother in law has some powered EV speakers. I think they are SXa 120 or something like that. We put those on top of my MWM bass bins and it really gave them some weight to the sound.
Carrying those 8' wide bins around however, is nothing short of a pain in the.....
