Choose 4 ohms or 8 ohms for woofers-Professional speaker production factory
The impedance value of the woofer is one of the most common speaker parameters. The speaker impedance is the ratio of the voltage and current of the speaker input signal. At present, 4 Ω and 8 Ω subwoofer speaker units are commonly used, so which one is better between 4 Ω and 8 Ω subwoofer speakers?
From the perspective of volume, in the case of the same power amplifier and output power, the smaller the impedance value of the subwoofer speaker, the greater the sound pressure of the speaker, and the louder the sound; The better the submergence and control; if you want a stronger sound field and louder volume, you can consider a subwoofer speaker with low impedance; if you want a thicker bass, you can consider a subwoofer speaker with high impedance. In the listening environment, the sound insulation is good, and the sound of the speaker can be pushed to a large level. The 8Ω subwoofer speaker requires relatively less current intensity, and the power amplifier is less difficult to drive. If you plan to use the speaker in the living room, and the sound pressure and current intensity of the subwoofer speaker are not high, the 4Ω subwoofer speaker has a greater sensitivity tolerance, and the power amplifier can better drive the speaker. The higher the impedance of the subwoofer speaker, the better the sound quality of the high-frequency part; the lower the impedance, the better the sound of the low-frequency part, and the greater the impact of the impedance of the subwoofer speaker on the operation of the power amplifier.
Regardless of whether it is an 8Ω or 4Ω woofer unit, select a speaker unit with a suitable impedance based on factors such as the usage scenario and the impedance of the power amplifier.
