I have noticed over the last couple of years that newer speakers no longer have grilles on them. It seems wildly unsafe to have a bare tweeter that any slight accident can destroy the expensive piece of equipment.
What kind of speakers? I recently got some Klipsch home audio that have removable grilles. The look with the grille off definitely looks better if you don’t have kids and stuff IMO. I’ve also recently bought some Pioneer for my truck and they too came with optional grilles though I didn’t need them since they went behind the door panels.
