  Did you try to dampen the OB with a heavy (2kg) metal block (non magnetic - brass or lead)?
  I had the same concern about the harsh highs although my MK1 doen't have Gemini tweeters. I added a damping weight. Now I can say that I don't have any complaints at all. It is very cost effective and might solve your case too.

  Hi Doughter, I went through the exact same thing you are going through now. I now have no resistors in the circuit except in my home theater setup which uses a Receiver for power. Not going to get smooth sound there. If you are using a digital front end, the Magic Twins inserted at the preamp input from the DAC is very important. Next easiest would be a change of a driver tube if you are using tubed gear. Very surprising what that can do. Cabling can be a potential problem as well but most high quality cables will not contribute too much harshness but or course, some do. High capacitance cables seem to be the worst in this regard. Garden Hose cable for instance. (I am trying to go from least expensive to most expensive) Next, if you are using digital, a tubed non oversampling DAC like the Audio Note gear (the kits are reasonable in cost)really makes things a LOT smoother. One more thing (it's free!!) is to ensure that your speakers are not angled much at all. If they are skewed inward much at all the treble will be vicious. If they are close to a rear or side wall, some diffusion (like RPG products) will help a great deal. There is an added benefit that imaging will be improved as well. I think that Robert's worry is that by making the speakers work for really poor recordings you may lose too much when you put a good recording on. I went through this. Even with a switched resistor (one leg shorted, the other with the resistor in line) the switch itself can degrade sound so choose carefully in this regard. Silver contacts are really a must. Once you get your front end components sorted out, there is real magic to be had with these speakers. Best of luck. Please feel free to use the forum for questions. We are here to help.

    I should have mentioned that.

    I have the earlier Gemini in open back use. I have also installed the Jupiter bees wax in lieu of the obliggato months back.

    Also in searching around I see others who have tried to do same same with other speakers use an additional resistor in parallel to make a l-pad which differs from Roberts one resistor in series solution. However I think the l-pad seems to lower the tweeter output which may or may not be what I am looking for regarding cymbal taming.

    Unfortunately I realize in the end I probably won't be able to correct without sacrificing the generally great treble on good recordings, but would like to experiment and maybe luck out with a middle ground compromise solution.

      Hi,

      please give me detailed informations about your setup (room, placement, electronics, cables), maybe there is a more satisfying solution than lowering the tweeter- level. You also can send me a p.n..

      Regards

        Thanks Robert in offering to diagnose my system as you never fail to lend your time with Bastanis owners and may email you for your recommendations on improving my system.

        I would still like to ask for opinions if the single resistor in series is the only method to help with what should be a cheap fun experiment and in the end most likely probably wouldn't be a permanent implementation.

          Hi,

          a series- resistor is a quick- fix, you can mount it with a plug, so it is easy removable when you like to listen to your hq- records. You can try a single series- resistor (10W) per tweeter of one Ohm up to two Ohms, when you need additional lowering you better use two resistors and assemble a dividing- network. A single resistor of one Ohm reduces the tweeter- level about 2Db, a single resistor with a high value (above 2 Ohms) doesn`t add much additional lowering but changes the crossover- point of the tweeter.
          This quick- fix will help you like medicine which doesn`t cure the desease but surpresses the symptoms a little, so i recommend to follow a path which makes the poor recorded songs sound ok. and the good ones even better than now. For this i need detailed informations and your feedback when you followed my advice. This also cost you time only, you can try everything from my product- line like any other customer on return- terms.

          Regards
          Robert Bastani

            I'll give the resistor(s) a try and folow up with the results.

            I suspect the product you mention is the Magic Twins. Are they a specific frequency cut off/limiter and does it work in the area where hot cymbals live. If so I do like the idea of a specific frequency correction approach and may try it as well.

              Hi,
              there are many possibilities for harsh sound - from the source itself, the pre- amp, amp, cabling, power- cords, everything counts. The overall quality of your stereo is dependent on the weakest part of the chain. Especially when you have Prometheus with the Gemini- tweeters these speakers show you everythinng which is not harmonic like a lens - when everything is fine (this is not a matter of money, for example a Sony PS1 and a NAD 3020 connected with the Bastanis diy- cables to Prometheus sound fine - of course not on the same level as a highend 300B- setup but musical and satisfying) you get fascinating sound without getting disturbed by harshness or anything else which nobody would expect at this price- level.
              There are Magic Twins filterelements for I/C- connections and a different type for speaker- use, these filters doesn`t touch anything in the audio frequency- spectrum but depending on the setup they offer big benefits, especially a natural de- stressed response in combination with more details. There are probably additional or completely different changes to make you satisfied, my experience is that a good stereo- "chain" always offers natural sound AND resolution of fine details, this is the path i recommend. Lowering the tweeter- level offers less listening- stress with poor recorded CD`s but the disharmony in your setup will not be cured. You can try everything from the Bastanis product- line which i recommend for your setup for two weeks before you decide if it`s worth the money in your setup or not.

              Regards
              Robert Bastani
