Summary: These are great old-school speakers but...$1700 a pair. Really? I bought a new pair (unfinished) for $730 in the late 80s. For that kind of money I'd throw in a few more bucks and get some MartinLogan electrostatics.
Summary: the heresy has a horn tweeter and a horn midrange driver...the woofer is a 12 inch acoustic suspension driver..a true horn loaded loudspeaker will have a horn loaded woofer....the heresy does not. I know it is hand built in Kentucky but 1700 bucks is still a bit much for a pair of speakers!
Summary: Many audiophiles bewail the so-called horn sound of horn loaded speakers. I cant speak for other horn loaded speakers (not that there are that many others) but these simply do not have the so called horn sound.
Summary: I own a few pair of Klipsch Heritage speakers and I've always used the Heresy as a center channel. I have K-Horns, Chorus II's, Forte II's, Cornwall II's and Quartets, so I'm a bit familiar with the limitations.
Summary: I gave the Heresy high marks for features because it offers two sets of connections for biamping, a magnetically attached grill and a nice base that tilts the speakers up. Biamping is using two different amps to drive the speakers, one to the low end and another for mids & highs.
Summary: The Heresy III is a truly amazing little speaker, I use thrm for everything from Bolero to the movie XXX ( I like Vin Diesel movie) Although the lower limit id 58 Hz, everything is crisp and clear. These little guys provide tremendous sound ifromr really small floor standing speaker, Hmm..
