  1. Bob Crites discussed this very issue along with some others. He was able to make the necessary measurements and make an appropriate choice for the replacements. If someone was interested they could search the threads (I am not that someone) and get the details. Just stepping back for a moment ... c'mon guys, these are simple capacitors in straight forward circuits. This is not rocket science.
  2. I am not sure where to begin ....... Old capacitors have probably not appreciably drifted off spec in terms of capacitance. What folks worry about with old capacitors is ESR (Equivalent series resistance). This requires more than an inexpensive volt meter. The above post does not really address the issue at hand. In fact it is just noise in the discussion. While I am at it ... there is this myth being perpetuated (IMHO), that Bob Crites was unaware of how to measure and specify capacitor parts (functionality -- including acceptable levels of ESR). This is not true. In fact Bob had a nice post about how he was able to "work backwards" and figure out the functionality of how the original parts would have performed and measured. His argument was convincing. While I am still at it ... no one has fresh OEM capacitors that were used in some of the older Heritage products. Now, a vendor may claim that their products meets those specs, but is it fair to claim they are actually OEM parts? Should folks blindly repeat the mantra that these, and these only, are "true OEM parts". I think some of you folks are victims of advertising. IMO, I would not hesitate to use the either the Crites replacements (or the JEM replacements), but let's be aware of the sales pitch .... -Tom
  3. Kevin Klipsch, Please PM me if the Xilica XD4080 is still for sale. I would have PM'ed, but you do not have it enabled. Thanks, -Tom
  4. I think you are off target on this one. In fact, I really can't figure out where your comments are coming from. Granted, there are copies out there that are not very good. There are also copies that are pretty good and some that are remarkably good. The cost for parts alone would be shy of $3k, if you can get them. If you start making substitutions, then the result may become severely compromised.
  5. I'm glad it has worked for you. I still don't comprehend how a youtube video would help someone appreciate the differences between speaker systems costing thousands of dollars. In my world, especially if I was going to buy them, I would need to hear them in person .... not via youtube
  6. I am sure that you knew ahead of time that a "demo" of a couple of systems on youtube was going to be problematic at best. The notion of any sort of "demo" on youtube actually leading to a sale is far-fetched. Would you buy a car that way?. So, it sounds like this caused you a load of grief. Why did you bother to do it to begin with? You had to have seen it coming.
  7. I am not the point of contact on this issue. However ........ as of April 2021, Jubilees are available and at a price far less than what is being floated around. I only bring this up because folks in this thread and others have been discussing fairly expensive ways to improve their systems (fancy electronics etc). My contention is that for this kind of money you are now in the ballpark for buying Jubilees. My opinion is that Jubilees would truly be a significant improvement, especially when compared to fancy electronics etc. The new "new Jubilee" (not yet released) sounds exciting, but the price (according to rumors) puts it well out of range for me. I apologize to the OP for side-tracking his thread. -Tom
  8. VDS, Congratulations on you new arrivals. If I may ask, and I am just snooping, where did you buy these from? If you would rather not say, that is fine. Congratulations again ! It seems a shame to take power tools to them, but I understand your goal. Good luck, -Tom
  9. This figure of $20,000 for a pair of Klipsch Jubilees is inaccurate. In fact, it is not even close. I think those of you who keep repeating it should do some homework first. You are unwittingly scaring off potential buyers of a fantastic product. I am trying to say this in a friendly way, but I have become tired of this (unintended) misinformation that keeps being repeated. If folks want to buy Klipsch Jubilees, they are within reach. -Tom
  10. Well, a few things are being ignored in this discussion. First, "good design" will frequently result in a better system than "good parts". Second, the price is important. Let me say that again, the price is important. Well chosen upgraded parts (according to the system design) will cost far less than the price of $6000 for the new Cornwall IV's. Will it sound better? If it is good design, it just might. Personally, if you are going to spend that amount of money, you are only a few grand away for something that is truly a step up. Of course, that would be the Klipsch Jubilees. Wait, I just forgot about my second point that price is important. My bad ..... -Tom
  11. Simple question, simple answer. Get some Klipsch Jubilees.
  12. I think that is exactly what was going on. The Jubilee sounded like it was going through a low pass filter. My guess is that the mic was pointed directly at the Klipschorn (and getting a full bandwidth signal). I guess you need to listen to them in person ....
  13. Perhaps this is a typo. Did you really mean "EMI distortion" ?
  14. Dean, It is good to see you posting again. Jubilees are within reach. That never changed. As far as I can tell, one of the vendors posted (via the forum and Facebook) that the availability of Jubilees was disappearing ("this is your last chance" sort of thing) and that you had to buy a certain package that they offered. Although more recently, the vendor has tried to backtrack on what they originally claimed, but the rumor mill was already in progress. Keep in mind that my interpretation of the history may have some inaccuracies and I am not interested in arguing. I checked last week (of course, with a different vendor that I have dealt with). You can still buy the Jubilees for a price that you and I were accustomed to (roughly, since taxes on internet sales are in a state of flux). So, yes my guesstimate of less than 10 grand to get you up and running (Jubilees, DSP and an extra 2 channel amplifier) is accurate. Personally, I thought, and still think, that Jubilees are an incredible deal. The value (performance per dollar) is astounding. -Tom
  15. Sounds like you got a good deal. I used to own Klipschorns (AA - 1982) and enjoyed them immensely. It was later on that I got Jubilees
  16. Some of you folks have strange notions. For the prices you guys are talking about you can get a pair of Jubilees (No, it won't have the over-priced veneer), a DSP unit (No, it won't be the best but it will be good enough) and a second amplifier (Again, not the best but good enough). Add it all up and it will be less than 10 grand. Believe me, you will have exceptional sound. Hands down! Period ! etc .... Quite possibly the best sound you have ever heard. That is something to consider
  17. This will not be a popular opinion, but ...... If you want to bring your speakers up by 4 notches, then ..... do not buy a new amplifier ...... buy better speakers. The differences will be astounding, especially if you spend some effort on speaker placement (toe-in, spacing, distance for the walls, listener location etc)
  18. It is only worth $35K, if someone is willing to pay 35K.
  19. Are the Horns placed tightly in the corners? The room is quite large, the remedy could be Klipsch Jubilees. Keep in mind, that is my remedy for most things, -Tom
  20. Kevin Klipsch, the PM feature on your profile needs to be turned on. It would also be useful if your profile included your location.
  21. If a group of folks heard the two models side-by-side in the same room at the same time - Do you think folks would hear any differences and would those difference be judged as large or small?
  22. Congratulations on your Klipschorns ! Folks like to modify their systems, but not all modifications are upgrades. 1. Leave the woofers alone. They are not the weak link on a Klipschorn. 2. If you stay with passive crossovers, there are two strategies. One is to refresh the capacitors (many choices and at many different price points, including some ridiculous ones). While the other strategy is to redesign the crossover. I am quite skeptical of this later approach. In your listening to them, is there a particular problem that you are trying to address? Sometimes it may not be the Klipschorn, but something else. Good luck, -Tom
  23. Maybe I am a bit of a heretic. There is something about the "Klipschorn sound" that endures whether it is a Type A (I have heard these very frequently), or the Type AA (which I owned for a number of years), and the sample of various Type AK's (although I have not specifically heard the AK6). The strengths were all the same (great dynamics, great precussives and transients, and a strong & comfortable sounding bass). The weaknesses were all the same (idiosyncrasies in the mid range that were most noticeable with brass and woodwinds and some but not all vocals). Don't get me wrong. The strengths far outweigh the weaknesses. I love the way they sound. I think the voicing on all them seem to have the same focus. I have not heard these various models in the same room at the same time, but I expect that (beyond room placement and room contributions) you might have real difficulty hearing any serious differences between the two models you have mentioned. So now it is a question of price and cosmetic condition. Good Luck, -Tom
  24. Please back up a bit. What specifically is the application (2-way or 3-way)? Where are you guessing the crossover points might be. They claim the horn can be used down to 300Hz, but the DH1A is designed for a lower cutoff of 500Hz. Will that be a consideration in your design. Two things that jump out at me are 1) This horn has a 1.4 inch throat and the DH1A is for a 2 inch throat (adapters, especially going large to small, are not a good idea). 2) The vendor does not list any polar (dispersion graphs) measures on their spec sheet. How they might perform based on a visual inspection is problematic. Given that these horns are not inexpensive, I see some red flags. -Tom
  25. You might also try this question over at the DIYaudio forum. There is an active group over there interested in multiple entry horns. Many (but not all of them) of the guys are quite knowledgeable.
