I just recently got my hands on a 1972 Kustom 215b Cabnet and one of the 15's was blown on it when I purchased it. I'm wondering if anyone has any advice on to what kind of speaker I should replace it with. I am considering replaceing both speakers instead of just replaceing the blown one. Also I am not looking for the vintage sound, so any kind of speaker in any range of price is fine with me.
