Hi Salas. It seems like to get rid of it I will need a very solid support of some kind on that panel, we will see if I can make it. Aluminium sandwich seem interesting but not possible for me to make. This speaker company is rather interesting, a review of one model:

A slight dampening it is, better than nothing. In total the volume is 0,81 liter less now. Salas, what happens to bass when you decrease volume and keep the rest unchanged? Do you get a little hump the more you decrease it?

Ok, almost finished. After it is dry I put some new stuffing in place ( I ditched the fleece lining and removed all behind woofer while testing). I listened some more and also knocked on the back and it is clearly more stable, mission accomplished. Picture of inside, quite a construction site . The rib is 19x27mm with the smaller side against the back for max stability. With this placement it gives support on the whole panel behind woofer with just one rib, and gets support from the upper and lower bracing.
