This is interesting.
We also had this problem.
Someone traded in a pair of Maggies to us around 1991 that had this problem,
but it was with cigarette smoke. It was an enlightening experience, especially since these were the first Maggies we/I had ever had. When they arrived we opened the boxes the same day.
When the flaps of the box opened it literally smelled like the box was used as an ash tray.
Trust me, if this problem exists you will know it right when that box is opened.
We took the speakers, and the boxes, and put them outside (not stacked on each other) for 3 weeks. Brought them in every night due to the worry of the morning dew (and whatever else).
After 1 day it did nothing. After about a week they seemed a bit better. 2 weeks not much better. 3 weeks seemed to be when they improved. We had to toss the boxes in hopes that new smoke free boxes would help. We tried lightly sprinkling some scent free carpet powder on them and vacuuming it off but you have to be so careful and apply so little that it didn't seem to help. If you try that be CAREFUL! If this happened to us again we might also consider buying a fan and placing them in front of them at an angle (OUTSIDE).
There's also an issue about the tar from the smoke settling on the many contacts that ribbon speakers use. Maybe AgN should add a check off box for "Smoke Free" or "Smoke environment" for classified (and demo) ads.

Well, that's interesting, but where on the Maggies do you place the can?
