EV ZLX 12 G2 Cover

So i have both those models and the ones from the previous models ZLX 12BT, those ones have some hard material to the top and some small plastic legs to make the top of the speaker flat after you put the cover, that makes an a bit weak and unstable flat area over the speaker that doesnt make them feel safe to stack, and also when removing the cover for a gig as it has that hard material it takes space to hide you cannot just push them in a small bag like the old only fabric ones, and imagine 4-8 of them how much space they need.
