The spec will look something like W; W rms , or W peak. What is speaker power handling wattage rating? The speaker power handling specification aka wattage rating is the measured or theoretical limit of electric power the speaker is capable of handling before burning out. To understand the power handling ratings of speakers, we should understand what power is in the first place.
Electric power is defined as the rate per unit time at which an electric circuit transfers electrical energy. It is measured in the SI unit of watts W. The power amplifier in our signal chain provides amplified audio signals that can properly drive our speaker s to produce sound.
The transfer strength of these audio signals is typically rated as an amount of electric power in watts. Basically, speakers are transducers that convert electrical energy audio signals into mechanical energy sound waves. In the vast majority of cases, this is done via electromagnetism. The audio signal passes through a conductive voice coil, inducing a magnetic field that reacts with a permanent magnet to cause diaphragm movement.
Essentially, the alternating current of the audio signal causes a varying voltage across the conductive voice coil, which, in turn, causes the diaphragm attached to the voice coil to move in accordance with the electrical signal. The transducer elements of a speaker are called drivers. Why not be concerned with voltage and current itself? Though ultimately what audio transducers convert, electrical current is not a good measurement for electrical audio devices.
This is because audio devices like speakers and amplifiers have impedances. Electrical impedance resists the flow of alternating current. Since different devices have different impedances and these devices can be mixed and matched within a signal chain, current is rarely used to describe the specs of the devices.
There are just too many variables. Attempting to account for every connected device in an audio chain would be futile. Actually, voltage is generally used to measure audio signal levels and is regularly used in audio device specifications. We use this voltage to get a current. This current is resisted by the impedance of the audio devices in the signal chain.
So then, voltage is commonly used to measure signal strength. One reason is that, while the voltage of the audio signal and current in the signal chain will oscillate between positive and negative values current will flow in both directions , power is always positive.
In this way, power is a bit easier to understand as a value. Note that the AC power of an audio signal, like voltage and current, oscillates between a peak and a trough. It can be snuffed up to old nomenclature as a way to help us select suitable amplifier and speaker matches. Power ratings, in general, are useful and relate to voltage, current and resistance which we often replace with impedance by the following equations:. Of course, these formulae simplify matters of AC audio signals but can be used to effectively understand the way electrical power works between an amplifier and a speaker.
Speakers are required to produce sound waves out of electrical signals. This takes a lot of work, and when we factor in the inefficiency of the typical moving-coil driver, we see that speakers require amplifiers. They boost line level signals used in recorded audio, mixing boards, etc. With the help of external power and gain, amps will take line level signals at their inputs and output speaker level signals at their outputs.
The input is connected to a mixing board, playback device, etc. Another way to look at the speaker-amplifier connection is that the speaker draws power from the amplifier. This is commonly brought up when discussing speakers of different impedances. Amplifier outputs are rated with power as well. The power handling specification of a speaker is the maximum electric power it is capable of handling from an amplifier before it begins to sustain damage.
As discussed earlier, the audio signal alternating current flows within the voice coil due to the electrical power supplied by the amp. Some of this power is used to move the voice coil and diaphragm to produce sound. However, most of it is lost as heat due to the remarkable inefficiency of the speaker. Typically this heat is dissipated from the surface area of the voice coil as it oscillates back and forth within the magnetic gap. However, there is a threshold at which the speaker will no longer be capable of dissipating enough heat to keep the voice coil safe.
However, speakers can also be overloaded mechanically. The first is the point at which the speaker ceases to perform linearly. That is, it begins to distort. This maximum linear movement is defined as the point at which the voice coil has moved far enough outside of the magnetic gap that the coil no longer experiences the full magnetic flux density of the motor. At this point, the electrical audio signal no longer has as much control over the motor movement.
This results in non-linearities aka distortion in the sound produced by the speaker. The maximum mechanical movement is past the linear threshold to the point at which the speaker can no longer move.
This happens inwardly when the coil slams against the rear plate of the magnetic structure. It also happens outwardly when the diaphragm moves to the point of stretching its surround. Exceeding the mechanical limitations of the speaker leads to damage and can be caused in certain instances by supplying too much power to the speaker. Subwoofers are really the only speakers that may possibly reach their mechanical limits before reaching their thermal limits.
There are two main reasons for this. First, the voice coil of a subwoofer is relatively large and, therefore, better at cooling itself. More importantly, however, is the amount of excursion required of the subwoofer.
To produce the lowest frequencies of the audible spectrum down to 20 Hz , a subwoofer must push a lot of air. In addition to having a large diaphragm area, a subwoofer must oscillate great distances to produce low-end frequencies with any amount of loudness.
When too much power is applied, the subwoofer may indeed be forced into over-excursion where it will become damaged.
The most confusing part about speaker handling is knowing what the specification is actually referring to. We must understand the time horizon for which the power handling rating holds true. Will any instant of time above the rating burn out our speaker, or is the limit referring to the safe amount of power that can be sustained for hours at a time?
This is where the numerous variations of power handling specifications come into play. They include:. However, with the other values, we may periodically surpass the threshold without causing speaker damage. The peaks of a dynamic audio signal may very well send spikes in power to the speaker. Remember that power handling is mostly about heat dissipation. We can turn up the heat for brief periods of time so long as we bring the heat back down to a certain level for the majority of the time to allow the voice coil to cool off.
Unfortunately, there are quite a few variations of the speaker power handling spec, which causes confusion. Different manufacturers use different terminology and, even worse is, some have different definitions for the same terminology.
Peak power handling refers to the maximum power the speaker can handle for any instant in time. If, at any point, the speaker draws more than power the peak power rating, the speaker will sustain damage. Peak power is often the preferred method for marketers as it gives the highest wattage rating. Bigger numbers typically look better to the consumer. RMS root mean square is technically a measurement of the square root of the mean square the arithmetic mean of the squares of a set of numbers.
Alternating current and voltage goes in both directions, and so will both positive and negative values. This is easily seen in a sine wave. The average amplitude in volts of the above sine wave is actually 0 volts because the signal spends equal time and amplitude in the positive as it does in the negative. However, these signals still produce results and drive speakers.
The trick is to calculate the average of the absolute amplitude of the sine wave rather than the actual amplitude. For simple sine waves which have a single frequency and are typically used in speaker specification calculations , the RMS equation can be boiled down to:.
Using the Of course, audio signals are, by nature, AC, but this may help us to understand. Power, which we know is always positive, does not have a root mean square value. Rather, we can actually calculate the average amplitude of the power rather than relying on any root mean square formulae. Well, it should mean the average power handling limit according to the maximum rms voltage the speaker can handle. So then:. In the case of our example speaker, the average power rating would be equal to What do I mean by this?
Unfortunately, RMS power handling has come to mean the amount of continuous power the speaker can handle. This is technically incorrect though sometimes a suitable limit for speakers. Various tests can be conducted, testing for the power level that will, over time, cause the voice coil to burn out. In many cases, the pink noise used in the test will have a crest factor between 2 and 2.
In other words, the RMS value of the pink noise signal will be between 0. The crest factor is a waveform parameter that describes the ratio of peak values to the effective rms value. In other words, the crest factor indicates how extreme the peaks are in a waveform. A crest factor of 1 would indicate no peaks, such as direct current or a square wave.

The soundbar is a pretty genius product concept, offering many of the benefits of a full-fledged home theatre system while avoiding the complications of installing a multi-speaker setup. However, soundbars can be rather expensive, often costing as much or even more than the televisions people want to use them with. Budget soundbars do exist, but options such as the Mi Soundbar are perhaps too basic, and may not offer a significant improvement in sound over your TV's built in speakers. The Realme W Soundbar is the first soundbar from the company, and is priced at Rs. With this, Realme is looking to fill a major gap in the budget soundbar segment, and hopefully popularise the use of soundbars.
