P.M.P.O and R.M.S watts.

By Iqbal Khan

P.M.P.OAcronym for peak momentary power output.

This term refers to the maximum power output achieved for a speaker system under perfect conditions. PMPO is a controversy term, as many feel it is used as a marketing ploy, since the perfect conditions on which PMPO are based are next to impossible to achieve in a home where the speaker system is set up. The PMPO of a speaker is actually based on the maximum power output in a very small period of time (microseconds). Since no musical note lasts for such a short amount of time this peak performance cannot be reproduced in real usage of the speaker. The PMPO value is often seen listed as "watts PMPO" on product packaging. PMPO is also called peak music power output.

The alternative to PMPO is RMS (Root Mean Square), which is an accurate mathematical representation of a speaker's power output, measured over time rather than a few microseconds.

RMSAcronym for Root Mean Square.

RMS is the process used to determine the average power output of the speakers over a long period of time. RMS is derived from an equation which produces the most mathematically accurate measure of a speaker's power output. The RMS value is often seen listed as "watts RMS" on product packaging.

The alternative to RMS is PMPO (peak momentary power output) which represents peak output measured in microseconds rather than over a long period of time.

It is clear now that Real Power Measurements is in RMS not in PMPO , what I have noticed

is that where 1600 Watts P.M.P.O is written the system is not more than

5 watts R.M.S isn't that abusive for audio system holders that is written 6000 watts P.M.P.O but it is fact that those system contain audio amplifier of not more than 50 watt R.M.S.
