laserman16:And Ohms is a measure of resistance I think.
...and impedance.
Which in a speaker varies with frequency. Although speakers have a nominal impedance value, I have seen impedence graphs where the impedance swings from a low of about 2 Ohms to a high of 30+ Ohms, and that is for a speaker with a nominal 8 Ohm value. Its quite normal and nothing to worry about.
