There's a definite difference in sound between a Heresy and a Heresy II. The so-called Heresy 1.5 that was spoken about in an above post is a transition model, which was made before Heresy II production began. Klipsch ran out of the Heresy midrange drivers and resorted to using the yet-to-be-released Heresy II midrange driver. This created a speaker that used a Heresy tweeter and woofer but with a Heresy II midrange. They did this to be able to use up their stock of Heresy tweeters and midranges before releasing the Heresy II model. I would stay away from that particular Heresy 1.5 speaker myself. But let's talk about the "straight" Heresy and Heresy II models. If you were to A/B the speakers together on the same amp, you'd most likely walk away with the same impression as did I, which is to say the following: The Heresy I sounds more shrill, more in your face, with less bass, while the Heresy II sounds more refined, less shrill, with more bass. This makes the Heresy II sound more like a modernized, "tamed" loudspeaker. Keep this in perspective though. Saying that a Heresy II is tamed and refined is akin to saying the same about a captive great white shark. If you're looking for a tame fish, go find a dolphin. If you're looking for a tamed speaker, look for something other then a Klipsch Heritage model. You really owe it to yourself to A/B a pair of Heresy and Heresy II models in order to appreciate the differences. I tend to like the Heresy model myself, over the Heresy II. The mid to late 70s Heresy models are held in high regard.
