How much rms is good

You can also use a multimeter to measure amperage at the speaker. When working with a sine wave, the RMS value is equal to the Peak value, times 0. A device that uses 10 W of DC will be using the exact same amount of power over time as a device that uses 10 Wrms of AC. Skip to content. Search for:.

Home » QA. You may also like. You might be scratching your head wondering what these terms mean. Well, we'll explain in a minute. First, in order to understand the differences between "RMS watts," "peak watts" and "max watts," we need to first break down what these terms mean.

To help you understand this, we've created a very simplified graph that represents sound as viewed as a waveform on an oscilloscope. Looking at the graph above, the red line represents the sound waves at various watts.

The peak power rating is literally the "peak" of the waveform on the oscilloscope — the maximum voltage that the waveform will ever reach. Often times this peak value lasts only a fraction of a second. RMS, on the other hand, is an acronym for Root-Mean-Square and is essentially the average effective value of the waveform.

But what does all that mean? It should give you an idea of what you're going to be looking for, though. Agree with the above, you need a small PA, period. Luckily there are plenty of easy-to-use solutions. Your needs are pretty much the same as someone playing coffee shop gigs. That's a well-served market. I'm buying speakers. How much RMS?

It was my notion that all other things being equal, the more RMS power you have to each speaker, allows you to play that speaker at higher volume without distortion, and pretty much simply that. IamCatman's response indicates that there is even more dynamic range supplied with higher RMS. I'm not exactly certain what that means, though. I suspect dynamic range in audio is similar to the use in photography, representing the largest difference between the lighest portion, and the darkest region, and all the elements between represented as frequently and equally as possible..

So is it the difference in tonal representation frequency that can be produced, you can play tones accurately from 20Hz to 20kHz for example hypothetical with more RMS power, and would it also attempt equalize the decibel pressure from each tone? Im thinking about doing a 3 way active crossover system with a 5 channel amp.

Most 5 channel amps only leave about rms for the sub. Is that enough power for some good bass with the rear deck removed to port bass into cabin? Cause Ive seen youtube vidoes of people with rms subs and their cars are shaking, i dont need that. Originally Posted by randomy.

Attack eagle: great post. I like it.
