Impedance Question
 

Does anyone know what the speaker impedance is in the SWR WorkingPro 12? I'm trying to do an extension speaker setup and don't want to take the overall resistance too low. My Goliath 4x10 is 8 ohms. If the speaker in the amp is 8 I'll be OK. It just says 4 ohm minimum on the back of the amp. thanks in advance!

Ah found it. The internal speaker is 4 ohms.

I don't see where that amp has a speaker out.
