Hi I have had Klipsch Heresy IV's and Forte IV's. I didn't have the courage to buy and carry Cornwall's into my small place.
I didn't know what I was hearing until I head NSMT 100's. The difference between a horn and a silk dome covered tweeter was large. So before you buy more horns I would suggest hearing non horns then it may help you pick. I did like the sound of the Forte's over the Heresy's.
