Klipsch speakers are very particular about what you feed them. If this is a hassle for you, move on.
They are also very sensitive to placement. Again, hassle for you, move on.
Lastly, there have been numerous improvements in the Heritage line in the last few years. Don't base your opinion of Klipsch on a pair of 70s Lascalas that you heard back in the 80s being driven by a receiver in a less than optimal room. This happens a lot and people post their opinion as fact.
The new Heritage speakers are able to compete with anything in their price range and not be embarrassed. Sometimes way above too.
As for @jasonbourne52 and his measurement fetish, JA measured the Khorn on a dolly in Art's driveway. This is a speaker that is designed to use the corner of a room as the last fold of the bass horn. What would you expect that graph to look like?
