Magnepan mg1b speakers


I have an opportunity to purchase a pair of very nice mg1b magnepans which have been stored for the last 15 years. Anybody know anything about these speakers? I do not have a clue about them and cannot find any info anywhere.

You made a great purchase with these maggies, i love his wide soundstage. They are not the most efficient speakers, but they are still good.
I agree with the above responses regarding the repairs - they don't seem worth it since the MMG's are available for such a reasonable price. I had a pair of MG1's that I sent back to Magnepan in the early 90's to have refurbished. They sounded fine, but a few years back, I bought a pair of MMG's and although they were physically smaller in size than the MG1's, I thought the MMG's sounded better. I later traded up to the 1.6's. Good luck.
I had MG1s for well over 20 years. And thru a factory rebuild.

If you get them cheap enough and are willing and ABLE to do some DIY, there is no reason they can't serve you well.

Furthermore, even though they are not the most sensitive speaker, they can be made to work with 100/side or less.

Between the original model and the final there were 'a' / 'b' and 'c' revisions. I think they were crossover and cosmetic mods.

White Bear probably no longer supports this speaker. CALL them, since they don't do internet. Also, MUG (Magnepan Users Group) should be on your short list of bookmarks.
One more comment. I believe as mentioned above, the most common failure mode is the glue bonding the plastic and wires deteriorates. There is another issue to consider, however, and that is corrosion. My MG1's required re-build because the high frequency section was not working. It was not due to amp clipping or overpowering them, I was told by Magnepan that the speakers were internally corroded. This is dependant on storage environment, but it is another consideration.
