Hi Jim,
Thanks so much for the detailed information. My dedicated listening room is almost to the inch, the same size as your bedroom- the difference is that the back wall opens up to the living room and there's an open doorway to the adjacent kitchen.

I'll about to assemble some DIY broadband panels and the info here will be a great help. I'll report back as soon as I've got the room roughly configured. My equipment rack is in the living room which leaves only the stand-mount Sonus Faber monitors and a thick area rug in the room itself.

Good luck with the project, Paolo. Looking forward to your impressions once you're up and running with it.
