Klipsch Heresy vs Forte

The dog is my favorite part of the video. 

Had them both. Forte is a much better speaker. 

Love my Heresy IIIs and did not like the plastic diaphragm in redesigned mid horn of the IVs, preferring the sound of the titanium IIIs. Have wondered if the Forte IV suffered the same as the Heresy. The Heresy requires a good front end for sure, and with that they're great (I use a couple of REL subs with mine).

The entire IV series has the upgraded mid-range horns.  If that's not your cup of tea skip the Forte IV.  I think many would agree it was a welcome change, but you can't please all the people all the time.
