Flooring advice on basement listening room.

Whilst it’s true that cement slabs are better than wood floors since they’re much stiffer, you’re not out of the woods yet because seismic forces, including Earth crust motion, cause the entire building, including the cement slab, to move in all directions. Like a boat 🛥 is moved up and down and all around by waves passing under it. That’s why seismic isolation is beneficial even for rooms on cement slabs. When you isolate something you’re isolating it from the entire building and the motion of the Earth. 🌎

geoffkait. You're talking about extremely minute movement and at very infrequent times here. How does this affect one's system???

No. That’s what you say I’m talking about. 

Well, I guess if you ask a stupid question, you get an idiotic answer.....

Don’t shoot me, I’m only the messenger. If you don’t know just say you don’t know.
