Lots of folks commented 3 or more years late, then wondered if it mattered any more since the thread was old. I am here to say that the thread is as current today, as it was over 20 years ago. When the thread was started, Heresy's were in Version II. Posters had know idea the Version III was coming out in a few years (2005). Now here we are, Version IV! brought with it more changes. But one thing remains the same. Brightness! Researching this issue is all I have been doing for 3 months. Learning about L-pads, auto formers, golf balls taped to the through of the mid range driver, to name a few. I've done nothing yet, but will at the right time. I say all this to say, keep the discussions going. It will help someone someday, whether it is tomorrow or two decades from now. I have learned a lot from this thread, and can say my research is over. Now it is time to evaluate everything I have read and learned. I'll keep posting with updates when I have some thing good to share. The first thing I plan to do is buy a good subwoofer. That may very well be the least invasive approach to getting this balanced out. V/r, Rob

I haven't. But funny thing, I just saw your message and also just this second sat down to the PC to start looking for a good sub. My DAC/preamp has a pair of balanced outputs available; or I would have to use a splitter on the RCA's to connect to a subwoofer. Please share any thoughts you have about how it should/would/might work. Thanx. Rob

I was thinking of something that could lower the gain to either the squawker or the tweeter. Maybe placed between the crossover and the actual drivers. I would love it had Klipsch offered something like that as an option. Or an aftermarket device. I may have found a work around though. I just discovered that if I toe-in the H-IV's to about 35 degrees from the back wall; and then sit behind the normal axis listening spot, I get a lot less glare. The sound stage is obviously further away, but that's fine. I never cared to be on the front row anyway. I just don't ever remember having to do that with the Heresy I's. I would back them flat against the wall and blast them. No glare. But I love the H-IV just the same and and bound to make them their best. A labor of love you could say. 🙂

Thx 83 LSIs for your reply. Means a lot. Was the idea to drop the gain, because the horns are so sensitive/and/or bright sounding? You can tell I have a lot to learn.

Twenty years to late for some incredible ideas and people that understand and appreciate them.

Besides the tubes, does anyone know what modifications are in the Horn Mono's that make them more suitable for horn speakers? That would be good info to have to teach me more about horn speakers and what I have with the H-IV's. I Thx, Rob

Lighten up Francis!

I have only hear great things about the Willsenton amps. The build quality looks excellent as well. Congrats.

There is certainly a lot of charts and graphs. One problem though, is the set up. The wrong placement was used for both the listener and the speakers. The manual says to start with the listening point on axis, then move around until you find the sweet spot. That wasn't done. No one does that. That's like putting a bull horn up to your ear lobe. The ideal spot, most experienced horn aficionados agree, for the listener is 2 or 3 feet in back of the axis point. Do that and an entirely new and warranted world of sound appears. Secondly, rather than have the speakers set up in a corner or even near a wall, they are in the open somewhat. That isn't recommended in the manual. Not following the OEM manual and not following the position of the majority of experienced Klipsch owners, immediately runs afoul of the ANSI standards for home stereo testing; and general scientific procedures. Science is only science if agreed on standards, OEM recommendations, and the scientific process is followed. Another interesting point to me, is that the conclusions are opinions, and not supported by the data. Again, from a science perspective...that's neither help nor useful. It's also misleading. There appears to be a measure of confirmation biases going on and likely why the test set up was the way it was. The set up presents the speakers at their worst position. Makes no sense unless that is the intent. Thankfully, one test is only one test. It does not even come close to....let's say....explaining why millions of owners love the sound; let alone offering anything useful when understanding the horn sound. Notice too, the tester has taken contrarian views on several controversial speakers. From a business perspective...that may be smart. You create the event (in this case posting radical test results), and then lead folks to visit your website. Getting them to your site brings you clicks and visitors. That's business. No matter how you get them there, your site value goes up and the more money you make. Expect more controversial test results in the future. Remember, complexity isn't accuracy. Fancy charts and graphs founded on the wrong test set up are meaningless. Would any one buy the newest item on the Taco Bell menu, knowing that it had undergone one and only one test buy a guy in his garage? Hmmm. My two cents.

I have the same issue with a brand new set of Heresy IV's. Do they all sound this shouty bright, or could I have received that 1 in 100 where the squawker makes more than a few pieces of music un-listenable (if that is a word). I love these speakers and want to get them right. NAD CS1 Tidal Endpoint ----> RME ADI 2 FS DAC/pre with EQ ------> 2 WPC SET 45 (Alan Eaton) ----> Heresy IV (using Mogami cables 10 ft.) I am grateful for any advice, ideas or thoughts. Robert Marshall/Danville KY

I want to live in that studio!!!! Incredible!

Congrats!

Thanks all: mboxer - I guess. But I hardly even know what I am saying since I have no technical knowledge of these devices/components. I came across the idea of "L-pads" and "autoformers" a day or so back. Since then, I think I saw an image of an automaker, but not an L-pad. I came across them googling for ways to attenuate power to horns. I am 95% content with the Heresy IV 's because I listen mostly to acoustical tracks and some jazz guitar (Pat Matheny. If you have not listen to his stuff....please do. It's insanely good and sounds amazing on Klipsch horns - other worldly good). But ever once and a while, I want to listen to something else...and the horns can sometimes come across a little bright. So from there, I starting thinking, if there was some sort of device that could be integrated with the crossover (or not integrated with the cross over and placed between the crossover and the horn terminals) that could be user controlled. I agree too, the IV's crossover is a very different monster. I long for the old style...it's like the VW motor of old...you could find and fix anything. Sure appreciate everyone..and I hope I did not stir up any anything with my questions or post. UPDATE: As soon as I posted this I started googling acoustic "L-pad" and was introduced to a new world I never new existed. So this idea of tuning horns has been around a while. I don't know if I will ever do it, I might never be able to justify it...but if the Heresy's came with it...I would not object in the least. Just seems like it would be a worthwhile feature.

Langston and all other esteemed posters!!! Enjoyed this discussion a lot. As a relative new comer and a proud owner of Heresy IV's, I've been wondering about this very same thing (I think...) lately....and clueless about any of it. All I had in mind was some "device" that might be installed on the existing crossovers that would allow the user to "adjust" the power on one or more of the horns. The came up when I was faced with a lot of room treatments to tone down the highs. Sure would be a lot easier to adjust the horns. From what I read here, my idea was far from new. Similar devices have been used in the past. From you experience, would a device like the autoformer work on, say a Heresy, the same what it worked on a K-horn or the other big ones? Thanks. Rob

I had that same thing happen, but it ended up being the RCA cable into my amp. I swapped speakers and equipment for days...till I discovered it was one bad connector on an RCA cable. Might check those.
