So I got a pair of these (early V1s) and I honestly think they sound great. Since I can’t open the front grille to inspect the rubber, how do I know if they need to be refoamed? Sorry if this is a super basic question, I’m new to speakers in general. I should add, I already tried to take off the rear panel but am finding it really difficult to get out, and don't want to keep trying unless it's really worth it. I do have the plastic piece that holds the terminals already out so I can kinda look inside if that helps. Also, I don't really understand how OP got the back of his. And tips will be greatly appreciated!
