I've had Klipsch speakers for most of my life including the La Scalas, Cornwalls, Chorus II, Forte II, CF3 (excellent speaker), and many others. I would say that if you've never experienced a Klipsch speaker the way it was intended, then you're missing out. Kinda like driving a fast German/Italian sports car. You hear and feel the excitement without totally losing refinement.
Now, not always! Sometimes those horns annoyed the crap outta me sounding honky and brash. But that was normally a terrible recording or me running low res mp3s straight from my laptop.
However, at $15k, Klipsch better refine the crap out of the Khorn and use top quality everything.. No phase issues with front panel resonances. Did they not test this?
Btw, I had to brace my La Scala side walls as they resonated pretty bad.
