The Portuguese Adam distributor Audiolog lent me a pair of S3X-H and S4X-H to try. I'm going to replace my Barefoots.
I have to express my gratitude to the excellent customer service Audiolog as served to me. I have these 2 pairs with me for almost 2 months now!!!
I hoped that the problem would be solved by the time I got the Adams but it didn't happen, and the distributor has let me keep the Adams in the meanwhile.
I don't usually do publicity to distributors/dealers, but when a service like this is given I can't let it pass without giving it's recognition.

Back to measurements:
So I changed to the Adams S4X-H.
These are the monitors I used for the measurements, they're in different positions. I left them like this on purpose to check how they would react differently.
The left one is completely outside the Basstrap and the Basstrap has 9cm Rockwool panels 70Kg/m3 panels installed behind the monitor. Behind the panels, there is also low density rockwool filling 1/2 of the Basstrap.
The right one is inside the Basstrap space but it doesn't fit all inside, so part of it is outside the Basstrap line
Back Basstrap before I placed any Rockwool packs inside
It is currently with 9cm of Rockwool 70Kg/m3 panels but no low density behind.
Rockwool panels packs placed on the back.

The difference is not much as I expected, this is a monstrous basstrap, and the dip is still there.
I made the test again but this time with the packs opened, and reaching the ceiling. It didn't made so much of a difference comparing with the packs unopen
Just a reminder that the monitors are in different positions:
The left one is completely outside the Basstrap and the Basstrap has 9cm Rockwool panels 70Kg/m3 panels installed behind the monitor. Behind the panels, there is also low density rockwool filling 1/2 of the Basstrap.
The right one is inside the Basstrap space but it doesn't fit all inside, so part of it is outside the Basstrap line
