4, 4 ohm coils in parallel is a 1 ohm load. In parallel with another 1 ohm resistor =1/2 ohm load. However that is straight resistance. In the audio world, impedance is frequency dependent. Did that make sense? Anyway why on God's green earth do you need a 1/2 ohm load?
Been at 1 ohm for a lil and just wanna move on down. But what is the equation for get'n ohm loads, when you are use'n a resistor? I got .6, with the one I work out. Sounds right, but not sure.
