  1. I have reinstalled my original K77 Alnico. Before I describe the comparison to the K77M and my K77 Alnico of remagnetization (from now on K77) I would like to say that I do not know exactly about the K77M if they have the original diaphragms. I have never opened them. I bought them in April from an ebay dealer. He had butchered a very good condition 1981 Heresy 1 because the parts bring more money. I saw all the photos because I was also interested in the K55V dual phase plug but the price incl. shipping and customs was absolutely unprofitable for me. So I strongly assume that the K77M have their original diaphragms because the Heresy looked like it had never been opened, really. My 6 months with the K77M. To put it bluntly I was very disappointed. For this reason my preface about the originality of the diaphragms. The M sounds flat and unfortunately also very metallic. It has more energy than my original K77 before remagnetization. I do not want to talk further about the M. It made the whole speaker sound "flat" and two-dimensional even without soul. The existing volume of the M did nothing to the overall sound of the Lascala. The M did not "marry". The K77 was already very emotional before the remagnetization...in quiet passages, mainly strings. But overall it sounded metallic and spiky in the negative sense. Now after the remagnetization I a) do not recognize the K77 and b) the whole Lascala sounds like transformed. My hope for effect that quiet strings sound so beautiful was completely exceeded. The issues reported about a K77 are absolutely reduced to a minimum. So the fried bacon hiss in particular. (As described in the other thread I will rework the openings in the motor board. this could also mean a positive effect in this context). But now the whole Lascala down to the bass sounds much more authoritative with joy making impulse with a grin on my face. The mids are much more articulate and there is no separation between squaker and tweeter. You'll just have to take my experience on faith. That's all I can do. It's such a big difference from the K77 M that I'm seriously tempted to put the M back in and record both tweeters in comparison. If it is more than psychological illusion then one must be able to hear the difference in comparison objectively on youtube with headphones. The frequency response of the K77 is now so that they are powerful in their lower frequencies and the highs are again existent that were no longer audible before the remagnetization. but they are very silky and pleasant on the ear. generally a softer slope than the K77M. Overall, the workshop measured a gain of 1.5 db. I asked for it again in writing today and they confirmed it. I wanted to have the measurement but they said that was not saved and it was measured in the near range and that is not so meaningful said the store. Anyway...the difference is significant. I am especially taken by how incredibly powerful impulses of snares etc. in the middle have now become. The diaphragms were tested (on one of the tweeters) against brand new ones. they did not suffer and were left original. With the K55V it was different. Their diaphragms had become much worse in contrast to new ones I installed. Next i will have my K55V remagnetized but i don't know if i will experience such a wow effect as with the K77 again. Anyone who has K77 alnico give them a chance before installing something completely different as a tweeter. My K77s have never been abused yet they have lost significant magnetic power over 44 years. Then the same will be true for your K77 because no one is younger than 42 years. Man am i glad i gave the K77 (and myself) that chance. All in all including shipping within germany it is 56€. A huge step towards the new originality of my Lascalas. Please believe me, not a single word is an exaggeration. And I have not smoked herbs....

  8. Getting ready to spin Bella Fleck and The Flecktones. It's a new test CD to judge changes in my gear so I'm listening repeatedly so I can pick out nuances. Normally I would select Saxophone Colossus or Way Out West by Sonny Rollins. The change will be two nos Amperex 12AU7s made in Holland late 50's early 60s that will go in the center positions of the PrimaLuna integrated. Not sold on tube rolling so we will see....... Then taking LF to lunch on this sunny but chilly day. So there you have it.....feel free to alert the press🙂

  11. Just wanted to put a plug in for AC Infinity's 120mm USB fan. I had disconnected the fans in my Crown X1000 pro amp because they were loud enough to be annoying if I was listening to music quietly or during quiet parts of movies. Wanting to keep the amp cooled I looked for a USB powered fan that I couldn't hear from my seating position. I found the AC Infinity one on Amazon for about $13. I have it plugged in to one of my TV's USB ports so that it's always running when my TV is on. It has three speeds but I found that any speed higher than Low was audible from my couch. Fortunately even at its lowest setting it keeps my amp cool to the touch even after watching an action movie with lots of LFE. I have it sitting behind my amp blowing toward the opening where the original fans are. Working great so far!

  16. Outta the sleeve for me! Toss it on the table and crank it up if I feel like it. My first album was a commercial Tommy Dorsey lp I got from a couple guys that opened a gas station near me. At 12 or so I was all over the hood on my bike putting flyers under windshield wipers announcing their grand opening. Got all 3 that they offered. Even stuck a speaker on the front porch for Christmas carols for the neighbors til that got nixed. lol DJ'd in high school and put every penny of that $25 into lp's and tucked them away. NOTHING will ever change me because nothing has a better sound than vinyl imo. Still buying today 60 yeas later. I don't see anything changing soon. It's all personal preference imo and I'm VERY comfy right now.

  23. Well, my wife told me to leave the 402s alone and not paint them. She likes the sound and doesn’t mind black. The damaged pair are in the basement so she doesn’t care about looks down there, and the pristine replacement pair are on top of the Klipschorns in our teaching studio and she thinks black makes them less omnipresent. A truly understanding and indulgent person!

  27. Back in 2008, I picked up a pair of 1989 Heresy IIs near Vancouver (the one in BC, not the one in Washington State) for $275CAD. I couldn’t believe the price on Canuck Audio Mart, but since I was going to the mainland anyway, and I’d be close to the seller’s address, I stopped by for a look. He’d just painted them with flat black paint, but they sounded fine, so I bought them. He had lowered the price, but found no takers, so he lowered it again, then I spotted his ad. The seller needed the money to help pay for the La Scalas he had just bought. Classic! I still have them. Sometimes apparent bargains are what they appear to be.

  28. Vinyl still has a life in my opinion. Pops and clicks are inevitable but can be kept under control. Bad source will always be a bad source. A lot of negative opinion regarding LPs is connected with having heard bad or bellow average systems. Nothing new saying that vinyl require some involvement. When I first heard my 40 years old Philips GA 212 with NOS stylus connected directly to Onkyo stereo receiver phono input I was very disappointed. After that introduced was a good phono amplifier in between the two. Much better. Than Installed Ortofon 2M red cartridge. Better, but after a few months I have realized that alignment was not perfect. After realigning the cartridge by myself I believe I have reached the reasonable sonic output of this setup. It is decent but my ears told me the sound could be further improved. Decided that I wont quit on vinyl and I purchased decent turntable with a decent MC cartridge, aligned by the technicians in the factory. Everything else remained the same. Again good amount of improvement. I feel no need for much improvements after this, but of course there is room for that in the future. To put things in perspective, this vinyl setup can be compared with good digital setup and at the same time tick all the boxes that I like in vinyl.

  36. The best way to paint a horn is by attaching the horn driver flange to a turntable, so you can rotate the horn as you spray the paint, starting at the inside bottom, rather than walking around a stationary horn. I made a turntable from an old office chair. Remove the seat, add a piece of wood as a four bolt horn adapter, screwed to the office chair base swivel mount.

  37. I have seen these discussions turn into arguments but I hope we are adult enough to discuss a topic civilly. I would like to think I am good at my job which has me working with lab grade test equipment and working with extremely complex systems, I really have to know what I am doing including exactly how capacitors function in all regards and choosing the best types to be put into space for the rest of it's life. Often we do tear downs of our old products and go through them to see what can be improved upon for future revisions etc... Let's address the elephant in the room first. Someone that has a notion in their minds that capacitor a is far better than capacitor b and is anticipating an "improvement" upon something will have expectation bias. There is a HUGE psychological element to this where books could be written about that aspect alone. Whenever we remove this element in serious blind tests the drastic hearing difference claims fall apart. The mind starts to play tricks on you on what you hear and you no longer are absolutely certain about a specific capacitor making any difference at all. This is comparing functional parts of correct value appropriate for the application. If you have failed or drifted components then yes of course there could be a sound difference. Some very old caps indeed could have drifted off spec but still function fine but the filters have changed voicing and this could be audible, today you can order a tolerance of 1% where the older style large oil filled types klipsch used may be slightly off even from the factory when new. You mentioned ESR, great lets discuss this and how it applies to what we are doing here. Lot's of techs use an ESR meter, this tool almost always tests at one specific frequency and it is almost always at around 100Hz. Let's also put some numbers to the filters and discuss how an increase in ESR effects the functions. Let's look at the AA crossover for the tweeter, specifically the 2uF and 245uH second order high pass filter. We will use a two frequencies to view and model what is happening, first 100Hz which should be attenuated and not reach the tweeter and second 10kHz which should pass through the network and reach the tweeter. Now a modern film capacitor will have a very low ESR, usually much less than 1 ohm, this is usually stated at 100kHz on a datasheet. It is important to note the ESR changes with frequency so when discussing ESR it is vital to note the frequency to which it was tested, if tested with a meter it is typically around 100Hz. Let's put some numbers to the parts at the two frequencies. 2uF capacitor impedance - 100Hz = 795 ohms 10kHz = 7.95 ohms 245uH inductor impedance - 100Hz = .15 ohms 10kHz = 15 ohms When 100Hz signal enters the network a voltage divider of 795 and .15 ohms forms and less than 1% of the signal gets to the tweeter. I have tested many of the old klipsch oil type capacitors and their ESR can reach up 8 ohms at 100Hz, yet at 10kHz it is still less than 1 ohm, this is why I say it is extremely important to test the capacitor ESR at many frequencies and not just use an ESR meter which will give non-engineer types the wrong impression. But let's assume that the ESR has risen to even 10 ohms at 100Hz, how does this effect the crossover filter? It will add to the 795 number giving us 805 ohms of impedance. How does this effect the filter? It actually rolls off MORE of the lower frequencies since the impedance is slightly higher, but really it makes no difference because we don't want 100Hz getting to the tweeter and the capacitor with the high ESR still does it's job well, actually better since impedance is slightly more. Now a 10kHz signal enters the network, we have a divider network of 7.95 oms and 15 ohms, this means 65% of the signal gets to the tweeter. Here is where ESR does matter, IF the capacitor does have more than 1 ohm of impedance you may start to get losses, the modern film caps klipsch uses in the 1994 Chorus will certainly not have an ESR higher than 1 but we are talking about the old big oil filled caps so let's just add 1 ohm to the numbers making the 2uF capacitor 8.95 ohms. We have now only dropped 1% from 63% of the signal reaching the tweeter to 62% reaching the tweeter. When dealing with the AA crossovers of 1982 that I own 5kHz and up were all less than 1 ohm of ESR but at 100Hz the 2uF caps measured roughly 5 ohms ESR and the 13uF was 2 ohms ESR. I do not lose any sleep that at 100Hz the ESR is 5 ohms more because it is moot in how the cap functions in the circuit, and as I have actually proven it will actually HELP what we want to do by decreasing the low frequencies to the tweeter by having the impedance slightly increase at the lower frequencies so replacing them you actually worsen the goal of the part by allowing a very small fraction of the low frequencies pass through, but I doubt the 5 or even 10 ohms will make an audible difference since we are already below 1% of the full signal. It is great to see folks discussing technical things like ESR and capacitors but you need to understand ESR and also the application before making judgements. I get it though, when someone shows you some reading on an ESR meter that a capacitor that should have a low ESR has an ESR of 5 ohms many would assume this is bad, and it very well would be in other applications but it is vital and I cannot stress enough understanding the application is of utmost importance. As I have shown the slight increase in ESR at 100Hz is moot, you go from 795 ohms to 800 and with in filter network makes very little difference, and the actual difference it makes is actually a good thing as it helps impede the low frequencies to the tweeters. IF you do have grossly high ESR at 5kHz and above with the capacitors then I would start to agree to replace them but of the older style capacitors I have measured from my own heritage series speakers and friends of mine they seem to still have a low enough ESR at the frequencies of interest which is 5kHz and above. I actually put more weight into the actual capacitance value as that will make a much more drastic difference than an increased ESR at low frequencies because as I have shown that actually HELPS our cause. I can go into this further and bring phase into account but I am sure that will bore most people, my concern was to give people reading a better grasp at the function of these capacitors and using real numbers to show what is happening so this ESR scare doesn't cause anyone to lose sleep. If you do have a local tech that is scaring you with ESR numbers have them plot the ESR over a wide range of frequencies so you can make a better judgement of to replace or not replace because a meter that measures ESR at low frequencies tells us nothing. The reason the meters test at 100Hz or 120Hz is because that is what our power is transmitted at and so they figure that is what is of importance, they don't know you want to test caps in a speaker crossover network.

  38. I have a Great Appreciation for all the adopters of the “Underground Jubilee” who believed enough in the wisdom and vision of PWK and helped to keep it alive..!!! I hope all of them appreciate this fact as well as the determination and dedication Roy has always shown since I have known him for PWK’s wisdom manifested originally in our “Underground Jubilee”. Roy truly believes in PWK’s wisdom and knowledge and that it should continue and be developed now and well into the future as far as possible. Since I have known Roy I’ve seen this determination and I’ve heard him many times talk about his mentor and friend PWK and you can see all this manifested in the development of the new Jubilee and Roy’s dedication and efforts for the Klipsch Museum of Audio History (KHMA) where he hopes to pass that knowledge and wisdom to as many as possible. “Underground Jubilee” will always represent something very special and unique in my way of thinking..!!! miketn
