@ gdnrbob,
As RV himself told me in an e-mail concerning my used pair of Quatro Woods that are long out of warranty, "You bought them, you own them". I really don’t think he would be opposed to using the fuses but like I said, if your pair are under warranty, I wouldn't do it as I think he would not be too happy for one to disassemble the speaker and would most likely frown upon it, but out of warranty, that is a different ball game.
