1000w rms is how much pmpo

After all, you need to know whether the speaker will actually fill your room with sound. So if PMPO is of little use for working this out, what can you use? Alternatively, you can use something called RMS. This is an arguably more scientific and accurate measurement for knowing whether speakers will be right.

This makes it a much more accurate and useful measurement to use because you can get a much better understanding of what the speakers will actually do.

For example, if a speaker has an RMS of W, this means it can comfortably produce W over a period of several hours. On the other hand, a speaker with a PMPO of W can only produce this momentarily, and therefore is of little use for deciding speaker power.

If you take this value and times it by 0. Considering speakers are generally used for periods of time rather than momentarily, you want to pay attention to its consistent power output.

Choosing the right set of speakers can be difficult, but there are a couple of things you should pay attention to when buying a new set. Here are my top tip for deciding which set of speakers will be best for you based on their power and other factors.

This is by no means an exhaustive list, but these are just the most relevant factors based on things like PMPO. For example, if your amp can put out W of power, then purchase speakers with a power output of W or less.

Choosing speakers with a higher power output rating than your amp can cause the system to blow, or can cause damage to the components. Instead, just make sure that all your components match up when choosing them. The same logic still applies, but if you have your eye on a certain amp then build your system around this.

So to be honest, PMPO was created for cheating people at the shops. When we speak about amplifiers, it is power that amplifier can produce at all time, without any damage. There is also some compare with voltages. You can very easily check that by testing current by multimeter and than check at the oscilloscope. You will see that measure instrument will show while amplitude of current at oscilloscope is If it is rated in PMPO, there is a good chance that it is junk.

The frequency and amount of distortion aren't specified so could be anything. Peak power is simply double the real power. So Peak Music Power is meaningless. Thunderchild New Member. I think this pmpo thing only lasted a few years as now they are all back to rms but don't take their word for that either my 10 W woofer on my 2.

All i see in higher power than necesary is better quality at a normal power level. EM New Member. However, that can vary quite greatly as some RMS measurements are taken at 1khz sine wave only and don't quote distortion.

My new Hi-Fi amplifier is rated at 2x40W, the same as my old one, but it is significantly louder as it is measured across the full frequency spectrum and distortion at all levels is under 0. RadioRon Well-Known Member. We still suffer the equivalent of PMPO mentality in power tools.

Its surprising to see a small woodworking router or vacuum cleaner rated at 5 HP! They must measure the HP of those motors that have brushes when they are stalled and are beginning to smoke.

RMS is the correct value to be used and quoted over which frequency range. Used to be RMS at a steady 1 kHz frequency from my memory. As already said applies to powertools too, 1kW drill yeh?? Looking at the motorsize, perhaps Watt, they probably quote the power rating with motor armature in locked position, It may draw 1 kW, it will only last also a very short time prior to go up in smoke and sparks.

Cheers Raymond. Last edited: Jun 3, Honest Power Ratings: The most honest way to rate a speaker is to give the rating as continuous RMS watts ex: watts continuous rms power. You may hear speakers advertised as " watt 6 x 9s" or " watt 6 x 9s" and you may instantly think that the " watt 6 x 9s" are better and will play louder than the speakers rated at watts.

Then you should ask if the rating is in RMS or peak watts and are the speaker ratings for instantaneous or continuous power. Most car audio speakers with the exception of some subwoofers are rated in peak power or music power. Only a few speakers generally the higher quality speakers are rated in RMS watts.

While peak power is a legitimate way to rate speakers as long as the manufacturer tells you that the power rating is in peak watts , it can be deceptive. If a speaker is actually capable of handling watts of peak power it would only be rated to handle 75 watts RMS. If a speaker is rated to handle watts 'music power', it may mean that the speaker will take only very short bursts of power approaching watts RMS.
