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 .

I've had Klipsch-Horn and La-Scala and the Forte. I don't like "horn-shout" is that ok ? And like I said the Forte was the most musical of them all.
And my tastes if you search are big ESL's.
