First introduced in 1957, the Heresy, a three-way design, started out as a compact center channel speaker to accompany the Klipschorn® in three-speaker stereo arrays. In 1985, we made some changes and improvements to this model and re-released it as the Heresy II. Today, the new Heresy III has a more powerful woofer, a bi-wire network, and a titanium diaphragm tweeter with a larger magnet assembly. The midrange compression driver also features a new titanium diaphragm. All of these changes result in improved tonal balance and increased output. In fact the Heresy III is three decibels louder (96 to 99dB), improving on its already high sensitivity. In addition to delivering smooth, dynamic and low distortion sound, the Heresy III is available in a high-quality cherry, walnut or black ash wood veneer finish. Included is a slant riser base for floor placement that can be removed for cabinet installations.
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. The dispersion quality is excellent. Depending on what speakers you have been using before hand you will be hearing sounds unheard prior to using this speaker. What may be considerd the best part of a speaker like this is that it can be driven by a low powered tube amp and does not require a 200 watt monster amp. These really are incredible 'little' speakers and one is doing himself a dis-service not to give them a listen. I have had them for about 3 months now and it still amazes me that the sound they produce is coming from such a small box.
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. I also have Forte II's and Chorus II's as well, and they all have that very efficient and smooth throughout their frequency range.
