Choosing the ideal model of wireless outdoor speakers manufactured by Amphony is not easy while faced with a big number of various terms and specifications, for instance “sound pressure level”, “output wattage” and so on. You may not even fully understand the most fundamental of these terms, for example “speaker output wattage”. I will clarify the specification “speaker power” a bit more in this article. “Output power” is one of the most basic terms describing loudspeaker performance. On the other hand, it is often misunderstood. Various vendors also in the past have utilized this specification in a deceptive manner to conceal the real performance. If you are considering to get a couple of speakers to install in your house, you will often be faced with a series of strange terms describing its performance. But how do those numbers relate to how the loudspeaker sounds and how are those to be interpreted? Let me now proceed and explain the output power spec of loudspeakers.
“Wattage” shows how loud your speaker can sound. If you have a small space then you don’t need much more than several watts. If you wish to set up loudspeakers in the open or in a live concert then you are going to require a few hundred watts of power. For optimum music quality, you may wish to go with a speaker which offers bigger power than you require given that many speakers will exhibit rising distortion once the audio power goes up.
A number of specs will give the wattage in “Watts peak” whilst some will give “Watts rms”. “Peak” means that the speaker is able to tolerate the power for a short amount of time only while “Watts rms” means that the loudspeaker is going to continuously endure that amount of power. The peak spec has been to some extent misused by manufacturers displaying excessive peak audio power while their speakers are in reality tiny and unable to handle more than merely a few watts rms power.
Nowadays most loudspeakers will specify rms power that provides a better hint of the speakers’ actual performance. Then again, please make certain that your speaker offers sufficient headroom to avoid clipping of the signal. This is since at certain points in time the music is going to show peaks of power that by far exceed the average power of the signal. Typically the impedance of the loudspeakers that you attach to your power amplifier is going to determine how much output power your amplifier may deliver. Loudspeaker impedance is measured in Ohms. Normally speakers have an impedance between 4 and 8 Ohms. Due to the restricted supply voltage of your amplifier, the largest output power is going to be half if you connect an 8-Ohm speaker than the peak output power that the audio amplifier can deliver to a 4-Ohm speaker. Usually a 4-Ohm speaker is utilized as a reference.
