Understanding Speaker Power Rating

There are many speaker specifications to think about when buying new speakers. Your speaker’s capability of delivering good sound depends a lot on the speaker power rating. Knowing power specifications well means you will prevent costly mistakes and get total value for money when trying to put together a sound system.

To help you understand speaker power rating specifications, we have prepared a comprehensive know-how guide. We recommend that you don’t buy speakers putting into account the speaker power ratings.

Here’s everything you need to know about speaker power ratings

Hooking up a speaker with an amplifier? There are different power specifications that come with speakers. Matching the power between the speaker and amp ensures that you get the best possible sound experience. If your amp exceeds the speaker’s power limits, there is a high risk of blowing your new speaker.

Now that you have gotten a little understanding of the relevance of the speaker power rating specifications. So, let’s shed some light on the speaker power ratings and specifications.

  • The power specifications for speakers and amplifiers are different

It is important to understand that the power specification that you will see for speakers is different from the specifications around amplifier power ratings, as the speaker doesn’t generate power while the amplifier does. The power specification for speakers is measured in watts. It refers to the power the speaker can receive from an amplifier without any distortion. You must check the watts per channel that the amplifier can output and that it is within the capabilities of the speaker without running the risk of damage to the speaker, due to over-drive.

  • Check the minimum value for the power

The minimum figure denotes the minimum power level needed to drive the speaker to create noise. With the help of the amplifier that delivers this amount of power, your speakers will be able to render good sound quality. However, unless you are driving 1000-watt speakers with a 10-watt amplifier, you have nothing to worry about.

  • See the maximum power ratings of speakers

Check the maximum figure, this is the power level the speaker can take before it begins distorting or clipping. Be mindful of the figures you see in the specifications, as they can be exceeded for a short period of time, without encountering any problems. So if the maximum power reads 130 watts, there is no requirement to hook them up to an amplifier which is rated at 1000 watts output. Also, one handy tip would be to be careful with the volume control as that will allow you to drive any set of speakers with any of the amplifiers, irrespective of the power.

  • Look for RMS (average power) or peak values (maximum power)

RMS and peak values are comparable when matching the power of an amplifier to a set of speakers. Ideally, you should compare two RMS values or two peak values. Don’t match the RMS output for the amplifier to the peak output for the speaker.

  • Power ratings and impedance

For 100 watts of RMS power provided by the amplifier into 8-ohm speakers, then the RMS power it provides will vary when attached with the 6-ohm speakers. For amplifier power specs rated at 8-ohms, then the speaker power specs should be gauged at 8-ohms.

  • Refer to the suggested range of amplifier power ratings

Look carefully at the specifications, for the suggested range of amplifier power ratings given by the manufacturer, 50-watts to 200-watts per channel is usually the range to refer to. A powerful amplifier will provide the required support by helping drive the speakers comfortably.

An amplifier and speaker power ratings should be close to each other, to get optimal performance out of both. Most contemporary speakers are well-equipped with features to handle a large range of power from most amplifiers and receivers designed for home use.
