Audio equipment

Speakers, Power, measurements.

Greetings. help with the following concerns please. 1.- How to know the power of a speaker or speaker, is it possible to measure it if you don't have the manufacturer's data? 2.- The power of the speakers is electric power? if so, having as reference a 600 watt speaker that works at about 24 volts, according to the law of Powers P = VxI, clearing intensity would be 600/24 = I that would be 25 Amps ...? It seems too exaggerated ... is it correct? 3.- What relationship should the power of an amplifier and the speakers have?

First of all the real power of a speaker is known by the manufacturer, I have seen 600 watt speakers and yet with a power of 100watts rms the coil took temperature and distorted with a strong volume. While others of quality supported very Well the power. second, the power in watts is given by the amplifier and the real one is in rms, that is, effective power. The calculation he made is for continuous power what is not used in a speaker if not the measurement of an alternating voltage provided by the amplifier For example, if you measure 24 volts of alternating on the 8 ohms speaker with the ohm law and the formula V2 / R or square voltage divided resistance gives a power of 72 watts, which is the real power that the amplifier is delivering over the load that is the speaker. Finally, the speaker must always be higher in watts, about 30% or more than what the amplifier delivers at maximum power so that it does not burn.

Excellent with my doubts 2 and 3, understood the explanation thanks, I only have the doubt of knowing what power a speaker would support, such as the calculation or I deduce without having any data from the manufacturer, just so as not to make the mistake of burning it when connecting to a amplifier that delivers a higher power than the speaker would withstand.

Unfortunately there is no formula or way to measure the power that the speaker supports. Only one can be guided by the construction part or by the data contained in the magnet or the box. But with the advancement of the Chinese speakers the powers are greatly exceeded of what it actually supports. A guide could be if the power pmpo and the rms power are indicated in the speaker, you always have to be guided by the rms power, although there are few brands that really have the real power that is specified.
