i'll see about getting some spades soon. worst case, i can wrap bare wire, but spades would definitely contribute to a fare cleaner more foolproof connection with these i think.
also, i dug around in my crap some, and found some pre-cut self adhesive velcro tabs that will work nicely for making the grilles easily removable.
i could be mistaken, but those latticework grilles, fancy as they may be, will surely behave much like the acoustic equivalent of a cheese grater,
and as such, i'm farly convinced that i'll be wanting to run these things with the grilles off at least 90% of the time...
