Need to find some covers for my Fostex FE206Es.

I see that Fostex sells some grills/covers for some of their drivers but I have yet to find any for the FE206Es. Does anyone have any alternatives? One of my dogs gets really excited when it is time to go o-u-t-s-i-d-e and he finally managed to take out the whizzer cone on one of my drivers about a month ago. No he did not get a treat that night. So I am going to be ordering a new set of enabled FE206ENs from Planet but I would like to put a grill over them. Anyone have any ideas?
