- Require more space than sealed enclosures.
The recommended enclosure size for a particular subwoofer will be specified by the manufacturer.
Frequency Response
The frequency response of a subwoofer refers to the range of frequencies it can reproduce. It is measured in Hertz (Hz) and typically ranges from 20 to 100 Hz. The frequency response of a subwoofer should be chosen based on your personal preferences and the type of music you listen to.
Selecting an Amplifier
Choose the Right Power Output
The power output of an amplifier determines how loud your subwoofer can play. It is measured in watts RMS (root mean square). The higher the RMS power, the louder the subwoofer will be able to play. However, it is important to choose an amplifier that is not too powerful for your subwoofer, as this can damage the subwoofer.
Match the Impedance
The impedance of an amplifier and subwoofer must match in order for the system to function properly. Impedance is measured in ohms, and most subwoofers have an impedance of 2 ohms, 4 ohms, or 8 ohms. The amplifier must be able to handle the impedance of the subwoofer. If the impedance of the amplifier and subwoofer do not match, it can cause the amplifier to overheat or the subwoofer to sound distorted.
