The two most common problems on audio speakers and amplifiers come from the wrong selection. One can avoid these problems if he can learn how to choose matching speakers and amplifiers.

There are two main causes of audio speaker failure. First, an audio speaker may receive continuous power from the amplifier that is greater than what it can handle. There are many speakers that were brought for repair. When the woofer coils are frozen or charred, they most likely suffered from overheating. This is due to using wrong power for the speakers. Second, when the audio speaker tries to get more volume from the amplifier than what the latter could give. This will result to clipping of amplifier that will soon damage the tweeter, the speaker in audio systems that reproduces high-frequency sounds.

You should understand that there are no standard ratings on amplifier and speaker power. Normally, speakers are underrated so do not even try to match a speaker and amplifier that are both rated at 100 watts.

It is easy to avoid having your speakers overheated and smoking by identifying the form of your speaker power ratings. You can easily compare speakers with RMS watts or average power with an amplifier with the same form of rating. An over driven amplifier should be matched with speakers that have twice the power.

One of the problems that you may encounter is when the amplifier is rated in RMS watts while the speakers are rated in Music Power or Program Power. The amplifier rated in RMS watts is obviously an average power that is defined by the heating effect. When the average power is applied to a speaker, a great amount of energy is converted to magnetism and sound. Some of the energy became heat that goes through the wire. Too much heat will wear out the wire. Having heat as the main culprit, you should focus on the average power if you want to identify the limits of your speakers. You can also overdrive the amplifier into clipping so that it will be producing twice the amount of power. In fact, it is recommend that you choose speakers with power ratings that are four times than the amplifier power rating. However, this does not guarantee that there will be no damages. It may also cause excessive distortion.

You should also take a look at the impedance value. The amplifiers and speakers should be compared only if they have the same impedance value. An amplifier may have a rating of 100 watts per channel to an 8-ohm load.

For problems in distortion, you should focus on the tweeters. As mentioned, this is due to the lack of amplifier\’s ability to produce the sound or volume that the speakers ask for. You just need to make sure that the amplifier\’s ability to produce sound matches the speaker without the need for over driving.

Simply put, you need the speaker program power rating and amplifier RMS power to be equal for considering that they have the same rating but you will need to double the amplifier RMS power for live performances.
