Question: what is the difference between 1 ohm and 4 ohm?
Answer: Difference between 1 ohm and 4 ohm The lower a speaker's impedance, the easier it is for an amp to supply power to it. So, technically speaking, the only difference between 1 ohm and 4 ohm is the amount of resistance a speaker's voice coil applies to the audio current supplied by the amplifier.
