[QUOTE="maylar, post: 7933646, member: 541144"] Your analog ohmmeter needs to have a X1 scale and be "zeroed" by shorting the leads and adjusting the zeroing knob (assuming it's an old VOM style). DC resistance of a speaker coil reads about 20% lower than the actual impedance but it's close enough for a 2 ohm v.s. 4 ohm check. If you use a digital meter be sure to short the leads first to get the zero reading. Subtract that from your measurement. [/QUOTE]
