Hi, sorry I took so long to get back to this. Got a little busy with summer stuff ( )
The price tag for the cross over and diaphragm upgrades is not too much of a surprise. These are stock speakers. we bought them new in 1989ish from Magnolia HIFi in the Seattle area. I wonder if they are even still around or if they got bought up by Best Buy or someone like that. I heard they did.
Due to the age of the speakers, I think I will start by replacing the old capacitors with equal value Solen or Jentzen?!?!?. I think Mr. Ex liked Solen best so I'll likely go with those.
Anybody have an opinion on how hard it will get if I attempt to do the same to the Marantz 2220B? For my comparison, I installed new capacitors in a 1948ish Philco floor model radio, a 1982 Furuno radar and a small B&K tube tester. They all worked when I was done and I had no parts left over. I'm pretty proud of that no parts left over thang! I also took about 2 years of evening electronics classes at a junior college.
Anyway, I think I can find the Crossover capacitors on Parts Express or,,,,well it's going to have to be Parts Express cuz I can't remember the name of the other company that carries Solen brand Capacitors. Dammit!, they also have a good line of coils too. Well, maybe it'll come to me.
Thanks so much for the nice comments and advice. Hope I don't become too much of a pest while doing this. And, if I need to start a new thread, lemme know, eh? Thanks again.
