As audio specialists, we value every detail of the importance that speaker power plays in the sound quality you desire. Therefore, we'll provide a guide to the different speaker power ratings available on the market. This way, you'll familiarize yourself with the more technical terms and have no doubts when choosing sound equipment .

How to measure speaker power


The power of a speaker is measured in watts (W) and indicates the strength with which the speakers are able to transmit electrical energy. This is the electrical "strength" of a sound-emitting device. Power is expressed in two main forms:

RMS (Root Main Square) power


It is the effective power value of a speaker's optimal performance . If the speaker is operated above this rated power, it may be damaged or deteriorated.



This is what we would call real or effective power and, therefore, the most important data to consider when choosing a device. This power measurement provides the most useful information when choosing between one sound system and another. It is, therefore, the power that serves as a guide when deciding on a purchase. In our brand's case, you can find a selection of portable or fixed speakers , depending on your style.

PMPO Power (Peak Music Power Output)


It is the maximum power value for a given period of time. It is important to emphasize that PMPO power is not a "real" value at all. It is sometimes expressed as the speaker's destruction point . Many manufacturers use this as a sales pitch to the consumer, but it is an unreliable figure, as it is the maximum power at which the speaker will break down.

As you'll see in our product listings, power is expressed in real power (RMS power). This is the measurement we recommend always considering when purchasing a speaker, as it's the most reliable way to determine a device's actual performance without straining its components.
