I think you'll find that the forte likes being less than a ft from the wall. I had my IIIs 10 inches from the wall and that seemed to be the sweet spot in my room.

Once you have them the right distance from the wall you'll know it.  Mine are about 10" away as well and the bass is awesome, no sub needed
I think the Forte IV bass is excellent,  while it doesn't have the pitch definition of a Cornwall it goes pretty deep.  I had a pair of Heresy III prior to these and the Forte are in a different league.    
Don't really like them much, too in your face, but I think the Forte are the most "musical" of all the Klipsch, but definitely not the loudest. I had the MkIII

Your tastes seem to be in the upper echelon.... Wilson , Magico.... which most can’t afford.   Why dis a speaker you aren’t even interested in, and I’m willing to bet you never heard the Forte IV .
