P.S. If you take a measurement without the speakers playing, how it looks like for measuring system's and room own noise floor?

Well I probably had flatter in some but I made many measurings at and near listening position and they all had a similar level increase in the middle range. I think some near field ones looked flatter. I will try to put some more stuffing in and also wrap the extra bracing I put in with it and see what happens. If I am right too much stuffing can lower bass output and then the balance is wrong anyway. Yes I will post a measuring with the room noise, brb.

But do you perceive more than enough mids as it is?

Mids are a little too much sometimes on that Nora Jones CD I mentioned before but better after I moved the speakers to the other room direction.

Also, the speakers are toed-in almost directly aimed at the listeningpos. so that trebel will not fall in level above 16kHz, maybe that beeming you mentioned gets noticed with that toe-in?

Too much residual in the measurement. Maybe you can still measure at higher SPL safely for Wattage when the speakers are playing? Try 5-10 degrees wider for toe in before doing something in the speakers themselves.

Ok here it is, I boosted the level a little, hope it is enough.
First picture is as it was, then picture for picture the less toe-in it is and the last one straigt ahead without toe-in. It is the lined out top level that you should read. They all seem rather similar.

Hmmm... It could afford less mids as a pair at that particular point in space, looks like only the brilliance range tames with toeing out, but I am kinda worried of that bass mode that now the mids level meets. I mean the ear has the trait to lock on things in relief, and maybe if you will try drop the mids a bit it could suddenly start dragging. But all it takes is a trial as always. Do you have a circa 0.25mH coil to put in series to the bass driver?
