Fact about WATTS PMPO In music systems:

Most of the people thinks that if music system label shows 2000watts pmpo then the speaker have the capacity to produce 2000watts

Truth is NO. So a speaker that has 2000W PMPO essentially means that the speaker is capable of putting out 2000W of power for a momentary amount of time, which could be microseconds.

If speaker were able to produce 2000 watts continuesly then it would damage the amplifier

So if PMPO is of little use for working this out, what can you use? Well at the most basic level, the speaker’s wattage is a perfectly acceptable measurement. Alternatively, you can use something called RMS. This is an arguably more scientific and accurate measurement for knowing whether speakers will be right.

For example, if a speaker has an RMS of 200W, this means it can comfortably produce 200W over a period of several hours. On the other hand, a speaker with a PMPO of 200W can only produce this momentarily, and therefore is of little use for deciding speaker power.
