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. They are very efficient and may have you reaching for the volume knob sooner than other speakers but the quality of sound will match any of the other highly touted brands like B+W or Magnepan. This is particularly true when one factors in the size of this speaker.
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. The two sets of speaker inputs are connected via metal strips. You want to leave these in place for regular use. They will be removed when biamping so each amp gets it's designated connection.
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...very efficient, very high quality, great tonality, kind of expensive...all in all it is a Kliosch Heitage Soeaker.
Summary: The Heresy III has incredible highs, tremendous mid range, a crisp bass line and very high efficiency. For [$] a pair these little guys are truly incredible, and are a part of the Heritage series that has made Klipsch the worlds best maker of speakers for 62 years.My Heresy II's had given me 20 years of reliable, high performance service, the upgrade was totally worth it.
Pros: Attractive Design, Compact, Easy To Connect, Great Sound Quality, Powerful
