[QUOTE="keep_hope_alive, post: 7358964, member: 576029"] you're measuring DC Resistance, not Impedance. Impedance varies with frequency and is affected by the free air resonance and inductance of the voice coil. DC resistance has many factors that influence it's measurement, even your DMM leads and the quality of your DMM. A $200 Fluke will me more accurate than a $20 Radio Shack model. Accuracy costs money. You're also measuring the resistance in the wire and connections you made to wire the coils in series. example of an Ultra Subs LV10 4 ohm sub: [IMG]http://i38.photobucket.com/albums/e128/phat_funky_beats/audio%20testing/Ultra%2010/Ultra10specs.jpg[/IMG] [/QUOTE]
