Hi Guys, I was wondering if someone could possibly tell me how can I measure the impedance value of an unknown speaker?? I want to build a cab for it, so that I can incorperate it into my present system. However, if it's impedance is incompatiable (unmatched) i.e 4ohm with a 8ohm I can't use it. It's a 12" speaker, which came out of an old blown 250 watt keyboard combo, but there is no info plate on it, stating ohmage. Is it just a matter of putting a 'Multimeter' across the poles, and it will give a reading of 4 or 8 ohms ?? Cheers, Rizz.
