[Cornwall IV Frequency Respond messurments?]

Hi Paul,  I have a few REW in room measurements from last fall.  They are a bit messy with room modes and such but I could share if you send me an email address.   I probably live 10 minutes from you, I'm in Chandler.

[Need a center channel for my LaScalas AL5]

I haven't studied your case but I have Cornwall IV's and ended up using a Heresy IV for the center.  It's excellent.  I referenced the tweeter / midrange descriptions on the Klipsch website spec sheet and was surprised to see the Cornwall IV and Heresy IV use the same tweeter / midrange drivers.   I don't think you're going to be as lucky though but hopefully this post will help a future person searching this topic.
