Hi All

So i have been looking at these canvas prints and been wondering if they wouldn't make excellent DIY acoustic panels with a bit of work?
https://www.onedayonly.co.za/star-wars-episode-vii-canvas-series-11.html

So the prints has a 4CM wide frame and you could get 40cm wide Insulpro panels(no name Uthermo) in 60/80/100/120/160 kg/m3 density.
So you could put it in the back of the canvas between the frame and just put some cloth with staple gun to seal it up and hang on wall with the usual nail or 2.

I know some peeps have mentioned that some canvas reflects hf but in my mind this would still have to be better than a concrete wall ?
Also which density would you use ? Seems general internet thoughts is 60/80kg/m3 for general acoustic absorption panel and 160kg/m3 for bass trap\absorption.
I have a large walls (3.5m high) and concrete ceilings so trying to reduce the reflection points in the room as well as just a general bit of distributed absorption ?

Any thoughts comments would be greatly appreciated.
