What Is the Difference between 4 Ohms and 8 Ohms?

Answer

The difference between a 4 ohms and an 8 ohms speaker is that a 4 ohms speaker generally needs a more powerful amplifier to power it. Usually at 4 ohms the output is 190 watts, but at 8 ohms, the output may be 100 watts. Ohm is the SI unit for measuring electrical resistance.
