Selecting the perfect model of wireless speakers is hard while faced with a large number of different technical jargon and specs, for example “sound pressure level”, “output wattage” etc. You might not even fully comprehend the most basic of these terms, for example “speaker output wattage”. In this commentary, I will have a closer look at one of the most fundamental of these terms: “speaker output power”. This term is also recognized as “speaker wattage”.
Speaker specifications are now and then tricky to interpret because they are not completely standardized. Thus it might be tricky to figure out the actual performance of the speaker just by looking at the specifications. A decent method though is to do a listening test prior to buying your speaker. During this test you ideally wish to set up the loudspeakers (Check out this website to help you come across helpful infos on the subject of powered outdoor speakers) in a comparable setting as your application. Let me now proceed and explain the wattage specification of speakers.
The power of the speakers is given as “wattage”. This describes how loud your loudspeaker can sound. If you have a small room then you don’t need much more than a few watts. If you wish to set up loudspeakers in the open or in a live show then you will need a few hundred watts of power. For superior music quality, you might wish to go with a speaker which has bigger power than you require since many loudspeakers will show increasing distortion as the audio power goes up. Power is either specified as “Watts peak” which means the speaker can endure short burst of this amount of wattage or “Watts rms” which shows how much power the speaker can endure for a longer period of time. In the past, vendors have usually favored listing the “peak power”. This figure is bigger than the average or “rms” power. However, “peak power” can frequently be misleading since there is no norm stating the amount of time that the loudspeaker has to be able to endure this amount of power.
Nowadays the majority of speakers is going to state rms power which provides a better indication of the speakers’ true performance. Though, please ensure that your loudspeaker has adequate headroom to steer clear of clipping of the audio. The main reason is that music signals are going to show brief peaks of large power that the loudspeaker has to handle. Rms power is measured with a constant sine signal that hardly compares with a music signal regarding the power envelope.
Typically the impedance of the loudspeakers which you connect to your power amplifier will determine how much output power your amp can deliver. Loudspeaker impedance is measured in Ohms. Typically loudspeakers have an impedance between 4 and 8 Ohms. Amplifiers have a restricted output voltage swing because of the fixed internal supply voltage. As such the highest output wattage of your amp will differ depending on the speaker impedance. The lower the speaker impedance the higher the maximum power your amplifier can deliver. Frequently maximum power is specified for a 4-Ohm loudspeaker impedance. On the other hand, ideally the manufacturer of your audio amplifier will tell which loudspeaker impedance the amplifier can drive. Please note that a number of amps cannot drive speakers with very small speaker impedance. Additionally, take a look at http://www.max.hi-ho.ne.jp/k1716v/thai/list92.shtml to get more details.
