I don't care for grilles but I have seen my grandkids change Barbie into Superwoman before and it would cause me anxiety with them exposed so, I opted for a compromise being the drivers in the horns are somewhat protected.
Plus, I put the gnarliest, most obtrusive, battle hardware looking grilles I could think of. I was going to incorporate knurling or some spikeyness to them to make them somewhat unpleasant to come in contact with, similar to the natural defenses of say a briar bush or other things that bite back but, I held back.
I'm no fashion Joe and have no real aesthetic sense but people were saying that even E.T. was cute so. . . .
At any rate, the look has grown on me and I like it and I can still see the drivers and I am sure these don't take away from the sound.
