Hello

First of all, thank You for the fast reply !

The recommended decay for a listening room your size is around .2sec
Right now in the high end your in the sub .15 sec range already. Adding more trapping will dampen it even more, so it has to be treated so it doesn't absorb above 300hz.
I am trying now to install reflective surfaces wherever I can, e.g. between the columns underneath the black fabric. I do test plywood and tiles. Moreover, I will install perforated HDF sheets in front of the corner bass traps. Thus trying to increase the RT60 up to 0.2. I am on it.

Where and what may be the cause ?

With this, You completely lost me. If the decay is too long, somewhere I should place absorption, right? Any guidance for finding that spots ?

Once again, thanks a lot for help and patience !
