I only got rid of my Hereseys to buy Cornwalls. I got rid of my Cornwalls to please my wife! I now have much smaller but almost as efficient Coincidents. In my opinion, if size matters, the Cornwalls are the best Klipsch out there. Hereseys take up as much space once on stands. Khorns, LaScala and Belle are HUGE and only marginally more efficient.
Also, the Corwalls are "old school" klpsch cabinet design with 3/4 plywood boxes. The whole company changes when they went to using mdf and cheaper materials for the horns. Now that HK has them, it's even worse.
Forte & Chorus are not from the original line-up. I'm very partial to the original klipsch.
Final note: My coincident speakers are almost as efficient, very tight and clean, smaller & prettier but made with veneer instead of plywood, have less bass and only lose out to klipsch when listening to horns/jazz or cranking at 125db!
