Wall mounts are often a compromise as they were put up there to get ‘em out of the way in the first place. Our little kitchen speakers are at around 2.5m above the floor: being angled down and in allows a decent listening experience for the dishwasher. That’s me.
Evazote might not be the lightest but I like the balance of firmness and protection that it gives. I've used old cut up sleeping pads made of the stuff to protect laptops et cetera when transporting in an unlined bag.
