Well, I got the crossover taken care of with new caps, the resistor and autotrasformer mod as suggested.
While I was there I got a new set of diaphragms from Bob Crites (one of the original one was in poor condition) and new gaskets for the midrange. Also one of the woofers had a tear on the cone. I was lucky to find a cheap replacement driver and I replaced it.
As soon as I played the first record I noticed the huge difference. I don't know how to describe it, but they are now really well balanced. What was disturbing before, it is now interesting. I can ear the people clapping their hands while the trumpet is not killing it. The bass is there too.
I played a little with positioning and the eq and it is even better.
I'm playing Thelonious Monk Quartet, some nice live recordings. Now I like those little speakers. My dog didn't leave the room, which is a good sign. I spent some time and money but it was fun. I'm gonna play some more known records and then try without the resistor and see.
Thanks for your help
