What does the power rating of a subwoofer mean?
The power rating of a subwoofer, typically measured in watts (W), indicates the maximum amount of electrical power it can handle without risking damage. This rating is crucial for ensuring that the amplifier’s output matches the subwoofer’s requirements. Exceeding this power rating can lead to distortion or even catastrophic failure, such as blown speaker cones or burnt voice coils.
In general, subwoofers have two primary power ratings: RMS (Root Mean Square) and peak power. The RMS rating reflects the continuous power the sub can handle over an extended period, while the peak power rating indicates the maximum power it can handle for short bursts. Understanding these ratings helps users select the right amplifier and setup for optimal performance.
How many watts can two 12-inch subwoofers handle together?
The wattage capacity of two 12-inch subwoofers combined depends on their individual specifications.
