I found this thread showing a diy expanded metal speaker grill and thought they looked great.. how would this look on a m80? would it affect sound quality?

I am tired of worring about my drivers getting damaged and the cloth speaker grills don't protect from kids and cats.
anyway i was just wondering if anyone else has thought of this or has any ideas where I could find expanded metal? maybe car audio shops? Ideas???
