What is the Difference in Sound Quality Between 4 Ohm and 2 Ohm Speakers?

[CaliLynn]

4 Ohm and 2 Ohm speakers differ mainly in three aspects. Below is a detailed introduction to these three differences: 1. Different internal resistance: The internal resistance of a 4 Ohm speaker is 4Ω, while that of a 2 Ohm speaker is 2Ω. 2. Different sound sensitivity: Due to the lower internal resistance, the voltage changes in a 2 Ohm speaker are more noticeable compared to a 4 Ohm speaker, resulting in higher sound sensitivity. In contrast, the 4 Ohm speaker, with its higher internal resistance, exhibits larger voltage changes and thus lower sound sensitivity than the 2 Ohm speaker. 3. Different power and sound effects: The 2 Ohm speaker has higher power, making it more suitable for playing high tones, which appear sharper, and is ideal for bass audio systems. On the other hand, the 4 Ohm speaker has lower power, making it more suitable for playing low tones, which appear deeper, and is ideal for high-quality audio systems.
