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.

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.
Magnepan uses lots of ALUMINUM wire. This is what helps the driver be light enough for quickness and is also where the corrosion starts.
2-edged sword.

If you pull the socks and have GREEN, that is corrosion.
I actually had a pair of MG 1B's that I bought new back in the 80's from Optimal Enchantment in Santa Monica, CA.

They sounded great as long as they weren't driven too hard.
