I have Klipsch RF 3II's and may have to put them 10" from the side wall to accommodate a screen. I can probably come out from the rear wall 18".

Will this ruin the sound or can I compensate with treatments and the receivers audio correction?

If you can toe them in to your MLP that will help and adding treatment at the first reflection point on that sidewall should do the trick.

The distance to the sidewall isn't a problem so long as you toe them in. The distance to the rear wall might be. When the distance from the baffle to the rear wall is 1/4 wavelength you'll get a reflected wave cancellation null. With 18 inches of spacing and the 16 inch cab depth the resulting 34 inch baffle to wall distance is 1/4 wavelength at 100Hz, not where you want a null. Tight to the wall the null would be at 200Hz, where it would be far less severe. The exception to putting the cab tight to the wall would be if the room is boomy, in which case the distance to the rear wall can be used to put the null at the same frequency as the room mode, taming the boom.
