I've been given a 2x12 speaker cab with 3 of these in. On the back of the speaker it says 15ohms - I've done a bit of searching and I found a guy who reckoned that 15ohm was really 16 - anyone know if this is the case. I'd like to use it with my JCM 600 head which I'm picking up on monday but I don't want to damage the amp if the impedance is wrong.

link to the guy who said 15 was really 16.
