@7c36db82 cool thanks :) For context using nixos unstable since about 4 months now and had only two broken builds (something about a kernel release that had a wrong hash committed and now this one) which is absolutely more stable than i expected ;) 

 @7c36db82 jep i know about the TAM fix, but i cannot even get a nixos-rebuild to finish in the current state, thus the warning. Flake locked at `NixOS/nixpkgs/f227f12d246b1e7916993c1e4c66f9f185d94586` (about 20 hours ago), at least that version still has the broken borg 

 @c76776cc the bad thing with speakers is always that it’s so subjective and cannot be conveyed over the internet how good or bad it really is. You’d almost always hear it yourself and then the personal preference kicks in 🙂 

 @c76776cc messier if it breaks but could work too 🙂 dampening would be better than plaster i think… if the sand is fine enough and does not vibrate itself against the plastic shell. I could imagine that happening if the space between walls is not big enough to filter all resonances 

 @c76776cc @5756e48c if that’s not stiff enough (or heavy enough) try printing without infill and plan a fill-hole for plaster of paris, did this for a smaller enclosure and it really helped kill resonances. 🙂
