I've owned many and heard them all. There's a reson the Cornwall's were resurrected by Klipsch and the Chorus, Fortes, etc. were not.
They're very good speakers that have a smaller foot print, which is what they were designed for, but Paul knew what he was doing we he used the big cabinets for the CW's.
I read that he disigned the Cornwall's to have bass performance on par with the K-horns, but in a cabinet that was easier to place, i.e. didin't require two good corners.
Obviously the CW's are my favorites. I'll admit the K-Horns and LaScalla's are more sensative, more detailed, etc., but they can also sound very sharp to my ear if the cross over's are not modified.
I always felt the CW's were much smoother and represent a good compromise.
