Only a small amount of work completed this weekend. I had other commitments so time was a bit limited.
Anyway, I did a bit of work on the framing for the front wall to ceiling corner chunk a triangular section of mineral wool about 80 x 30 cm. This is directly behind where the monitors will live. I'll most likely add something on the wall below later on but for now this will be all until I can test the room properly.
I firstly attached 4 vertical batons between the wall and ceiling and added two angled pieces to meet the corner chunks.
