I did put some gasketing under the driver, not thought but to so what it will do. I used the substance that I described above. It is Home Depot 3207680110 or the model #DS110 Pug duct seal by GB Electrical. The best thing about it that it is that plaster doe not glue itself to material and can be easily collected back.  I applyed the plaster only on one side of the driver, presuming the it shall jam them

The effect was very positive; the amplitude of the resonances went back and bandwidth of the resonances collapsed very much. However, the resonances did not go away and at higher amplitudes the speaker picks 1-2Hz wide resonances here and there, primary between 230 and 280Hz. Touching the screws do address them but it moved them to different frequencies. Now the problem not as bad as use to be and the resonances are not auditable during music playing.

At this point I do not know if I need to deal with it further. I never had an experience to have a good commercial speaker to drive at a lot of power from a generator with 1Hz steps and to see if it will resonate. I did it with a number of vintage speaker, those that conceded good one, and the resonated like hell, nowhere near what the MiniMe does. So, I do not know if it is acceptable.

Still, I think that it shall not be this way. I still do not think that it is the enclosure and to deal with it properly I need to eliminate any contact between the drivers and baffle.  Jessie was right – to use cork gaskets would be the right direction to do and I think if I would not found other means then I would need to buy the cork sheet and cut them myself. Meanwhile if someone knows any thick 4-5 gaskets then let me know. When I say “thick” I mean that I would like not to use .25 mm paper gaskets but rather 1-2mm cork-like gaskets…
