123a 3 Polarity

[Jim Hickey]

I'm replacing woofers in 4311 cabs with 123A-3. I'm confused about polarity. Negative is positive? What color wire goes where? Sorry for the head-ache.:blink:

The original woofer is the 2213H, correct? It is a negative transducer - (+) = inward cone motion.

The 123A-3 is also a negative transducer. So, the GRN wire should connect to the Red terminal. All is good...
