Thanks for the input, guys. I will check out the suggestions.
My front speakers, CA-8T are (or were before new cabinets) outdoor speakers: 8" woofer/driver with horn tweeter. They work well at very high volumes - but I am married.
What worries me about Klipsch speakers is this article:

As you can see the Klipsch crossover attenuates the mid range which is the opposite of what I want.
A three way speaker is mandatory, I think, to get the most mid-range.
