" Im looking into doing a slat type wall. It’s a large wall, twelve feet high by twenty-five feet long, in my living room. I’ve been investigating peel and stick acoustic tiles on Amazon, "

Which are you talking about using? Peel & Stck Acoustic Tile or Slat Wall? What do you mean by slat wall as that is typically used commercially to hang shelving and or hooks? What is the purpose of the acoustic tile? Acoustics or decorative?

Decorative, not commercial.

I looked at the reviews for Art3dwallpanels 10 Pack Acoustic Panels. I'd hesitate because one person said the panels got dirty and another that they couldn't be easily removed. I'd get the wood Art3d 2 Wood Slat Acoustic Panels instead.
