What is the difference btw Watts and PMPO?
Answers: Watts are the used to measure power ( mechanical or electrical). Therefore the watts written on speakers is their power output while PM PO is just a way to sell crappy speakers and fooling people :)))
PMPO stand for Peak Momentary Power Output, a truly worthless unit of measure, good speakers / amplifiers are always measured in watts RMS ( root mean squared ), PMPO makes the speaker rating lok artificially high as it measured for the small peak time a speaker or amp can hold the signal ( and I mean VERY short as in miliseconds ), but conmsidering any and all speaker can be measured that way ( and in that case you would see really good speakers with even more insane PMPO numbers ), but those that use the PMPO will fail in the true RMS, as true RMS rating reflect a speaker that can be driven at a given wattage all day long with a given amount of distortion ( very low percentage ), PMPO cannot and are very low threshold speakers / amps, hence the cheap PMPO rating to make it seem like you get a lot of power handling for very little money.
I think both units of measurement are bogus. PMPO is a ridiculous measurement designed to further confuse an already confused consumer market. RMS Watts are a measurement that describes a speakers ability to accept power for a prolonged period without damage. It doesn't measure how efficiently the speaker uses said power and it doesn't describe the quality of the output.
I would like to see a new industry standard unit of measurement introduced that with one glance will tell you power handling, efficiency, and frequency response. This is a pipe dream, because the industry likes to keep the consumer in the dark, but a guy can wish, right?
