Today’s wireless speakers produced by Amphony come in all shapes and sizes. Finding the perfect type for your application can often be tough. There is a large number of various names and terms describing loudspeaker performance. In addition, every producer shows a large amount of specs, including “sound pressure level”, “dynamic range” and so forth. In this article, I will have a closer look at one of the most fundamental of these terms: “loudspeaker output power”. This specification is also recognized as “speaker wattage”.
If you are going to buy a couple of loudspeakers to set up in your house, you will often be faced with a series of odd technical jargon describing its performance. But how do these numbers relate to how the speaker sounds and how are those to be interpreted? Now I am going to provide some details regarding “loudspeaker output power”. This specification is frequently misunderstood. It is important to look rather closely at how the producer publishes this spec.
“Wattage” shows how loud your loudspeaker can sound. Depending on your application, you can choose a small speaker tolerating only several watts or a bigger one tolerating a few hundred watts. Many smaller home speakers only can be driven with a few watts power which typically is adequate for a small room. If you intend to shake your walls then you clearly wish to opt for a speaker that has up to several hundred watts. Please note that many speakers will start distorting the audio once the audio reaches higher wattage. If you want to enjoy low-distortion music then you may want to go with a speaker which is going to give you more wattage than you will really require.
Power is either shown as “Watts peak” which means the loudspeaker can tolerate quick burst of this amount of power or “Watts rms” which shows how much power the speaker may tolerate for a longer period of time. The peak specification has been somewhat abused by vendors stating enormous peak audio power while their loudspeakers are in reality very small and unable to handle more than merely several watts rms power.
Music and voice is not constant in terms of loudness. As such the peak power spec is nonetheless important, though not as vital as the rms power spec. Ideally the loudspeaker is going to display both the rms and peak power rating. Having a high peak power spec will ensure adequate headroom for power peaks that are common in audio signals. Having enough headroom is crucial given that music signals vary a great deal from sine wave signals that are utilized to determine rms power. Brief peaks of large wattage are frequently found in music signals. These bursts will drive the speaker into high distortion unless the peak wattage is large enough.
Generally the impedance of the loudspeakers that you connect to your power amplifier is going to determine how much output power your amp may provide. Speaker impedance is measured in Ohms. Usually speakers have an impedance between 4 and 8 Ohms. Amplifiers have a restricted output voltage swing as a result of the fixed internal supply voltage. As such the highest output power of your amplifier will vary depending on the speaker impedance. The lower the speaker impedance the bigger the maximum power your amp may provide. Usually a 4-Ohm loudspeaker is used as a reference.
