I have high frequency hearing loss, which means I can hear dialogue but can't understand it well because I cannot differentiate consonants well.

I have the 180 center speaker now, with M80s on the side. I'm still not understanding movie dialogue. I have a new Yamaha Aventage RX-A3030 on the way hoping that might help (running a Denon 3312 now with a Behringer to push the M80s).

I've seen comments to the effect that Klipsh speakers are colored in the treble range. Wouldn't that help me? What center speaker brand might help me since the Axiom isn't working for me, though my wife loves it?
