rms....

can someone supply a detailed explanation for what this is please? i know it means root mean square, but does it mean the amount of power supplied over a certain time at a certain frequency?

basically RMS is the amount of power demand a speaker needs to reproduce sudden and I mean really guick and loud sound like gun shots, explosions, that kinda stuff.

Are you looking for a technical definition...? Or an explanation of what it means relative to speakers/amps?

I'm sure master Tempe has a link either way...I'm too lazy to type it out

damn it this thread made me read an entirely different thread. a wasted time in my life.

RMS in the form of an amp is the amount of constant power output the amp can handle putting out without overheating.

RMS in the form of a speaker is the amount of power the speaker can handle/will draw constantly without increased distortion.

who told you that. I was trained on what RMS is for and that sounds nothing close to it. Unless eomthing extreme happened and the diffenition changed w/o me knowing but I don't think that happened.

you're explination is horrible man. I've never heard anything like that. Sounds more like peak than anything. I don'tk now who trained you, but I think you're mistaken

What are we talking about anyways. RMS in DC voltage is the exact same as the peak but when it comes to AC voltage the RMS and peak mean different things.

alienjr's definition above is wrong

rms is the power you can expect from the amp "most of the time", i.e. average/constant power

peak power (max watts) is what you can pull out of the amp on a big bass hit

p.s.

rms is an abbreviation for "root mean square" key word being "mean" as in average

your defintion is the exact definition I was trying to get across, but I guess you didn't understand what I was saying. Well, according to the site I stated in my last post, it says that rms means the exact same thing as peak power in DC voltage but not the same in AC voltage.

speaker outputs = AC voltage

This Q is easliy answered..read plz!

http://www.bcae1.com/voltages.htm - description right there...must read

Note the first diagram...that pretty much sums it up

http://www.bcae1.com/2ltlpwr.htm - important link...read

from the above link...
"The RMS voltage of a pure sine wave is equal to the peak voltage multiplied by 0.707. The RMS voltage of a pure square wave it equal to the peak voltage. For 2 waveforms with equal amplitude (as shown above), the RMS voltage of the square wave is 1.414 times the voltage of the sine wave. If we use the example of the 100 watt amp which can produce a sine wave of 20 volts RMS, we can see that the output power at hard clipping is double the power it can produce cleanly."

i fail to see similarities, much less how the definitions are "exact"...

you define RMS power as "sudden and I mean really quick and loud sound", i define RMS power as "average/constant" and "most of the time" as opposed to "sudden" and "quick"

it just depends on the song, the example of mine is just of many but you thinking of a song with lots of loud point if the whole song isn't already loud. sorry if my example didn't make you think of it right but I hope you'll just let this post die cause I don't think the original question has even been answered.

yes, i suppose the thread can die, the definitions given, especially the links from spkrman, are sufficient to answer flinxsl's question, and if he has any further questions he can ask and recieve further clarification

yea the Q was pretty much answered...

but to comment on alienyoungjr, musical peaks have nothing to do with the actual power output of the amp..they just dictate volume levels.

Hey guys your still on this soap box, sheesh i thought we were going to let this die.
