    Forum member auditions my Jubilees

    Must have been a great time. Would like to see Schu opinion on Jubs and comparison with his LaScalas.

    Heresy II vs III

    You would have to be very patient and wait a long time if another pair like this comes up in near future for that price in France. I would take them. And negotiate to hear them first if you have a chance.
  3. Yes, the amplifier is in the system from the day of purchase. It was made by a company Sound Carrier, KT88.
  4. I hear you. Could be my hearing, not excluding that yet. But another pair of ears familiar with how the speakers sounded confirmed what I hear now. Until running some additional targeted tests (which I am unaware of except the one ChrisA mentioned above) I tend to believe its not the tweeters. I will investigate further. I had the speakers hooked up to a new push-pull tube amp rated 2x100W for a couple of years now. This should by any standards be enough. Additionally, I never play loud. My volume knob never passed 12 o'clock position, most of the time being at 8-9 o'clock position. They worked fairly good all that time, certainly better than after I messed with crossover. Yesterday I cleaned the fuse contacts with isopropyl alcohol and replaced 1,25A fuses with new 0,5A fuses. My ears say nothing much changed. However, lower rated fuses should be safer for tweeters. So, without further testing I tend to blame myself and my work on crossovers.
  5. That is also my opinion. I could have tried to clean up the fuse contacts and see if there would be any change. I don't know if it would be possible for me to find the AGC 1 1/4 fuses (metal thread in glass). However, I will follow the advice of the owners of the speakers and install 0,75A - 1A fuse instead of 1,25 as specified by Infinity. The originals seem to cause too many burn out tweeters.
  6. I finally found the time to take out the tweeters from the speaker boxes. Unhooked the wires an measured both drivers with ohm meter. One driver measures 3,8 ohms and the other 3,3 ohms. The later always had a bit more his when turntable preamp was on. This one also has a wire clips a bit more loose than the other driver. These measurements are in line with some comments on other forums indicating that drivers should be OK. Regardless of this I will try to find new fuses for the tweeters as this could be the next possible cause for tweeter performing badly.

    Testing Drivers

    Can you point out these problems or maybe provide some links explaining that? I am very interested to know more.

    The Sixes - Internal Preamp Quality

    I guess you found out by now that good phono preamp is essential if you want to play LPs. I was in a similar situation when starting this route. My Onkyo TX8050 has built in phono preamp, but I suppose that was the weakest link in that receiver. After plugin in a solid phono preamp things change considerably for the better.

    How many beers did you have in college?

    It was just a matter of 2 choices: how many bottles or how many different kinds of beer at a time.
  10. No I did not test the tweeter. How do I do that, sorry I am a newb regarding these issues? But I will mention a few things that seem relevant to me: I did not take out the tweeter. It is a panel-driver with strong magnets which I was afraid to touch cause I might have problems to put them together again. As these were Ok before, I had no reason to mess with them. I was careful working on the crossover so I can only say I did my best to avoid issues like shortages. I have touched one wire with the soldering iron but it did not come through the pastic to the wire, just a cosmetic issue. However, I put the electrical tape over it. The job on other speaker went smoothly and both tweeters seem to sound equal to my ears. The tweeter is connected to a fuse 1,25 A that is located outside on the crossover. Doesn't it help? Ok, some people advise to replace those with 0,75 or 1 A, but that is not relevant now. I only checked mid-driver and woofer detached from wires with the ohm-meter. They seem to measure ok, if they did not I would think twice regarding recapping.
  11. An update: I have recapped speakers. It took a while because I have very limited free time. I also sealed the inside of speaker boxes and braced them. It turned out that one capacitor for mid-range has already been changed because the originals are yellow as I noticed in second speaker when opened. Opted for Mundorf MCap Evo capacitors (aluminum) because of price and availability, and Mills MRA 12 watts resistors. All components are within or better than factory specifications, except I used 12 microF resistor for mid-range driver instead of 12,5. Soldering was done with amateur soldering station (58 watts). It was tedious job for me since last time I have been soldering was more decades ago. And the job had to be done inside the box as could not take the crossover out. Been careful and tried to execute clean solder joints. The most difficult part was to join three wires going from the speaker drivers together with capacitor wire on a speaker terminal. In such a tight space I once burned my finger and once touched the speaker wire. Happy that were all the injuries. 😃 I used new gasket when installing back mid-drivers. Gaskets for woofers were good, so no need to change them. When doing all that I also changed old clip-on speaker terminals for more modern screw type gold-plated terminals (had spares from old Mission speakers). Assembled it and hooked it all up yesterday evening for initial listening. Frankly, I expected more dramatic change. The improvements are subtle. Good thing is that mids are now more articulate than before, but still weak to my ears. The character of the mid driver did not changed. It seems that they were designed that way. The bas is a bit tighter. Highs showed the least change. If I have to pick out something I would say that they lost some of their mellowness and liquidity and remained detailed but more “technical”. Rumors are this is due to the nature of Mundorfs. Anyway, I do not believe in burning in the capacitors but I will give the speakers more time for listening. Time is now for some cosmetic changes on the edges of veneer and may be new grills.

    Forte III Impedance

    Just curious, what brand are the capacitors that Klipsch is using on that photo above?

    Has anyone used sound baffles...

    Experimented with just a touch of diffusion on the ceiling. It helped but have to mention that it was very reflective room, one glass wall, other parallel one empty concrete. A combination of absorption at the first reflection points, but only diffusion on the ceiling. It is worth a try.

    Bookshelves outdoors?

    E Exactly. A friend of mine got whole bunch of professional KV2 speakers for reparation. Speakers were installed on the beach by the sea for big rave parties. They lasted about 3 or 4 years and after that they need maintenance.

    Sit on it! (need office chair advice)

    I can imagine these morons can often get excited out of their orbit and away from nucleus ☺️
