I don't know about Klipsch horns, but I love the Merak (made by Axiom) horn center channel. The MC6H absolutely blows away the very expensive Infinity CC3 center I used to use. The Merak balances perfectly with my M60 like towers and M22 like side surrounds. What I love about this Merak center is its SLAM. I have not noticed any undue coloration or tonal mismatch with Axiom M50s, M3s, M22s or Michaura M665s or M55s. Just my opinion based on first hand experience.

Enjoy the Music. Trust your ears. Laugh at Folks Who Claim to Know it All.
