Ok thank you so much…i probably took it out on 11 because i remember that speakers had a really bad cabinets but that’s like at least 15 years ago

Ok I did a lot of reading on it and out of curiosity because I have a lst speakers that I got about couple years ago and I pulled the two mids on it and both reading also 6 ohms so this is A-12 or A14 on the restoration pages?

One looks like the 11, the other a 12. Not a 14.

Sorry my meter and the extra leads I use causes the ohms to go 6 ohms they actually measured 3.7 and 3.6
