I was getting a bit of uneven soundstage with having a large 10ftx8ft window to the left side of my room so decided to make a cheap free standing rockwool absorber to move into position when I’m mixing and to use when I record things with a mic.
Sorry if the parts are UK specific only.
First you need the stand. £17 room divider from Amazon.
It’s only 25mm thick as I didn’t need any bass reinforcement. You can use thicker ones but they’re more expensive.
Put the frame together, chop the a horizontal bar to the width of the panel with a dremal then screw some screws in the vertical bars holes and put some washes on to stop the screw from penetrating the rockwool.
I used a small screw driver to push a hole in the bottom of the panel and secured it with some cable ties.
Total cost £65ish. Took about 10 mins total from unpacking.
That’s not thick enough, you want at least 15cm to absorb mids. Around 5cm will only catch higher frequencies and if you want to build a bass trap you should go for 30cm.
Nice. I had the same issue many years ago. I happened across a pile of free standing cubicle walls on the street from some failed startup company. Took one home and it worked perfectly in front of my window. Just luck that it was the right height.
