Here at CompuBoutique we love music and how it makes us feel, that is why we know how important is to have good sound quality. We will explain you how to properly interpret the power of the speakers, the type of sound power it has and what types exist in the market so you can learn a little bit more about them as well as some technical terms you need to focus on when choosing a stereo First you must know that in a speaker the power is measured in watts (W), this indicates the strength of the speaker. There are different ways to tell the power of the speaker according to the manufacturer, effective or nominal power and (RMS), musical power or peak power. NOMINAL OR EFFECTIVE POWER (RMS) RMS stands for “Root Mean Square” and it indicates the level of power; its about the admissible power that the speaker can handle or tolerate before distorting the sound. This is the first important power you need to know to understand the power of the speakers. If you force the speaker above that nominal power you could cause irreversible damage since this won’t be able to spread heat produced by the electricity that circulates through the coil and this might melt the insulating that covers the copper thread. This measurement of power is what provides useful information when choosing a sound system and is also useful to compare between different models. The power is in fact what we need to consider at the time of making our purchase. MUSICAL POWER Is the amount of electric power a speaker is able to bear with an entrance signal of pink noise (sound that simulates any musical theme) without suffering any permanent damage. Normally the duration of this test is one second and it repeats 60 times within 1-minute interval. The value obtained is calculated over the nominal value of impedance, reason why when using the pink noise in ideal conditions you can get totally subjective results as well as less reliable.
