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! The klipschorn is a true horn loaded loudspeaker...the heresy is still a great speaker..Paul Klipsch was a true audio pioneer!
Summary: Starting with this speaker you step into a line of quality no other RF RB Icon or Synergy can offer up in sound.Made in the USA sounds great weather you use a tube or solid state amplifier.Not the mass marketed Chinese speakers that will burn your ear drums out.Beware this is a very natural and warm sounding speaker for a horn speaker.A real horn not the molded crap you get on the other stuff.Quality drivers and components an a finish on these babies that look like truly...
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. The bass roll off on these speakers is somewhere between 50 - 58 Hz, the material of the cabinet is irrelevant, it's the less than 2.0 cubic feet of cabinet volume that gives them the high roll off.
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 have spent the last 9 years going through a multitude of speakers, searching for the "perfect speaker" for myself. I had been trying to capture "The Sound" that was stuck deep within my memory of our old Magnavox console with it's tube amp, and dual 12's and Horns. Over the years as I was able to try some pretty decent speaker/amp combos I just never hit upon THE speaker that brought me right back to 1965. Well, my search is over!
Summary: I carefully studied speaker choices by doing a 2 day blind listening study. I sat in a darkened room as I listened to various types of music from different sources (CD-LP). The sales assistant switched between speakers on cue from my hand signals. After spending several hours over a two day period I narrowed it down to two different speakers. When I asked which they were I found them both to be Klipsch speakers.
Summary: Needed a high efficiency speaker for a new decware zen 6 watt per side tube amp. I wanted the best I could get and got that for a price reduction that was greatly appreciated by me. These speakers are fine furniture grade pieces for my room. They are like timeless works of vintage art. The sound is crisp and expansive. I am thrilled to listen to my large collection of all types of music as if the band were in my room with me, no kidding simpley amazing.
Summary: I own a pair of these Heresy's (I bought used, not from Amazon) and I can say they are the best speakers I've ever owned. I've had Advents, JBLs, Electro Voice, Altec, and several other lesser brands. There is just something about Klipsch that keeps me coming back to them. First, the sound. The horn loaded tweeter and midrange are both exceptional. Unless you've heard something similar, it is hard to envision just the amount of difference they make.
