I feel a driver needs to be somewhat hard-mounted to the enclosure. Cork gives the right sort of balance between hard-mounting and floating, while still sealing, however it would be a pain to cut that many gaskets from cork sheet.

It was ridiculously simple.

I bought a 1M sheet of 1.6mm cork. Then I discovered that my Cat’s tuna cans have the same diameter as my bass drivers in MiniMe. I took a fine blade and is a few minutes I had gaskets, cut to have slightly larger external diameter. Then I mounted driver with the new gaskets and cut with the blades the excess of the cork sticking outside of the mounted diver. It was extremely simple, fast and a fine fade cut cork like batter. Very cool!

It was ridiculously effective.

Now not of the divers touch the baffle and any resonances are absolutely gone. I driver the speaker all the way up and down at max volume and it has no buzzing of any kind.

It was ridiculously surprising.

What was surprising is not that buzzing noises were gone but the general quality of bass increased in incredibly positive direction.  That was what I did not expect. In fact I am truly astonished how much more interesting bass became.

It was ridiculously stupid.

Yep, I am not pleased to admit but I am an idiot. Chasing the buzzing noise I was driving the MiniMe from Lavry 924 full output and 100W amp with 26 dB gain.  I drove Lavry DAC from Lavry AD122 generator at -6dB digital and ran it from ULF to 400Hz. Well, it looks like I have burned the bass drivers and they apparently have no power handling at the levels that I fed to them. They still sound well and DCR did not change but when I give MiniMe bass section some volume then the speaker smells like  somebody fries a chicken in it. Sucks, now I need 6 more of those drivers…. How not to call myself an idiot!!!
