Great for protecting your speakers from scratches & dust (and a BIT of protection from humidity). But DO NOT MAKE THE MISTAKE I MADE and wash them if they get dirty!!! THEY WILL SHRINK a bit & will be VERY DIFFICULT (IF NOT IMPOSSIBLE..) TO FIT ON THE SPEAKER AFTER!!! They are already extremely tight, so with just a bit of shrinking after the wash, FORGET IT... :( :( I wish Thomann had warned about this because I sent about 50 (!!) covers to be washed at once and now I'm in serious trouble!! :( :(
