Hey everyone, I have a couple of questions about this JBL speaker, and hoping y'all can help me get some answers. many years ago, I picked up an old fender sidekick 30 bass amp for $30, (awesome little solid state guitar amps) it had this 12" JBL speaker in it. Right away, I swapped speakers in it with a celestion I had, and this speaker sat packed away for many years. I recently pulled it out to use in a cab, and measured it's resistance with a pretty decent multimeter and it reads 4.7 Ohms Question 1, hoping to get consensus that this is indeed an 8 Ohm speaker and will not fry my amp head. Question 2 - can anyone help me identify what model this is, this will definitely help me sleep at night knowing it is indeed safe for my amp. There's no numbers or markings except a round ink stamp that is worn away, see pic I can tell you it weighs a ton, frame is cast, the only way I know (think) it's a JBL is the wire clamps say JBL, I seriously doubt someone added them, but I guess you never know. Thanks everyone!!
