You seem to know little about electronics sir, resistance of a voice coil
has very little to do with its impedance. Some you can get 8 Ohms
resistance but different impedance. Resistance is only used for DC,
Impedance is actually a value of AC resistance.
Ohms measured in (insert Omega symbol here cause I can't find mine) and
Impedance is measured in Z's.
Seeing as audio speakers run with AC not DC (unless you want to F**K them)
the measurement of resistance is of no importance now is it.
PS: Impedance values can also change depending on frequency and other
factors but generally measured using a 1K Hertz tone.
Look forward to a response.
