Memorex WM-200 Upgrade - Minimus 7 Wannabe

I've had a pair of Memorex WM-200s on a shelf in the garage for years, but never paid much attention to them until i ran across the lengthy Minimus 7 upgrade thread (yes i read the whole thing). The resemblance was there, so I figured I'd apply the PZ 2.1 upgrade to them. The original crossover was a bit different than the M7s but equally basic. The mid-woofer looks very similar and the tweeter, looks cheaper, but similar as well. These may not be quite as good as the real M7s, but I have to say they went from mediocre to pretty decent. Well worth $25 in parts and a few hours at my bench. I may have to upgrade their status to basement listening. Here are some pics for the curious. Enjoy!

Hi Richard, did you only replace the crossover or other components, as well? I have Memorex 100s, so I'm thinking of doing the same thing. I also have some Minimus 7s, but they are perfect, so I decided I don't want to risk screwing them up (as this is the first time I would do something like this). Did you build your own crossover or buy something premade? I see that Parts Express has a bunch of premade crossovers--is there one similar to what you have here? Thanks for the advice. PS: I used to live in Ann Arbor--miss it.
 
Hi Eric. I made my own and only replaced the crossovers - everything else is stock. I did reuse the inductors from the original crossovers. Not sure about the PE crossovers. There is probably one that is similar, but the PZ2.1 design is pretty unique and it was a fun project to build them so that's the route I took. I figured the speakers didn't cost me anything, so I didn't worry about messing them up. Parts list attached if you need it (minus the reused inductors). Give it a try.

I went to school at U of M and ended back here in Ann Arbor in 1995 . . . been here ever since and wouldn't consider leaving. I love it.
