Mirage M1 Rebuild Project
I've had these speakers since new for 20 years. I decided to strip them right down to the bare cabinets when I found a dead tweeter. I thought this would be a good opportunity to upgrade crossover components, wiring, connectors, damping material and of course to have the tweeter repaired, since they are no longer available.
With the crossover, I'll would like to replace the woofer coils with air core. The crossover as quite a few electrolytics and frankly cheap film capacitors. I would like to replace them with polypropylene caps (Audio Grade). I'm toying with the idea of replacing all 4 tweeters with today's drivers, but frankly don't know where to start. There are literally hundreds of choices and yes I do realize I would have to alter the tweeter crossover components. Since the M1's are bipolar, I don't know how a replacement tweeter would work in this setup if I manage to select the proper crossover components. I was also thinking about upgrading the midranges as well, but don't know if that would be taking it too far. I've attached a crossover schematic for other M1 owners, this kinda of information is hard to come by. I've also posted a picture of the crossover as well. Any input would be appreciated. |

Thanx. I have lots of recovered tweeters kicking around, but none of those.

I replaced all of mine. ALl 4. Three were blown. I bought an exact match from Lee Barron at Lab Acoustics in Canada. They work fine, and they don't push out the fabric the way the originals did with their metal protective bar. Next, I have to work on a crossover problem. Low midrange on one side. If anyone has had that problem, I'd like to hear about it. Possible a tired cap.
