what is pmpo and rms power?

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.

In home theater, PMPO is an acronym for Peak Momentary Power Output and is theoretically a measure of how much power the speakers give out, measured over a short period of time. However, there is some controversy over whether PMPO is really an accurate and useful measurement to use.

Program is usually twice the continuous (RMS), and peak is twice the program (or 4x the continuous). Note: An RMS amp rating directly correlates to a speaker's "continuous power " rating. This power rating represents the most conservative statement of the capability of an amplifier. It is also called "RMS" power.

The root-mean square (RMS) velocity is the value of the square root of the sum of the squares of the stacking velocity values divided by the number of values. The RMS velocity is that of a wave through sub-surface layers of different interval velocities along a specific ray path.

MW is a measure of real power and equal to one million watts. MVA is a measure of apparent power and includes power factor which can be leading (positive) or lagging (negative) and always less than one in absolute value. These two qualifications are basically the same thing.

Yes they are equivalent and as Phil notes 100V DC is equivalent to 100V AC RMS. 100 V DC will produce the exact same average power as 100 V AC RMS. This is why the RMS values are used on all appliances and equipment.

Equals: 1.00 watts (W) in power. Converting joule per second to watts value in the power units scale.

Moreover, in power plant, power factor is 1 therefore MW is equal to MVA …… (MW = MVA x P.f).

Root mean square or simply RMS watts refers to continuous power handling of a speaker or a subwoofer or how much continuous power an amplifier can output. RMS values are usually lower than peak watts ratings, but they represent what a unit is truly capable of handling.

The peak value is the highest voltage that the waveform will ever reach, like the peak is the highest point on a mountain. The RMS (Root-Mean-Square) value is the effective value of the total waveform. It is equal to the level of the DC signal that would provide the same average power as the periodic signal.

Power is the product of Voltage and Current, “Amps ——- Power = Volts X Amps. Power, W = V^2/R, where R is the resistance. It is a directly proportional relationship.

“RMS” stands for Root Mean Square, and is a way of expressing an AC quantity of voltage or current in terms functionally equivalent to DC. ... Also known as the “equivalent” or “DC equivalent” value of an AC voltage or current. For a sine wave, the RMS value is approximately 0.707 of its peak value.

PMPO. PMPO, which stands for Peak Music Power Output or Peak momentary performance output, is a much more dubious figure of merit, of interest more to advertising copy-writers than to consumers.

Power Formula 2 – Mechanical power equation: Power P = E ⁄ t where power P is in watts, Power P = work / time (W ⁄ t). Energy E is in joules, and time t is in seconds.

HP= horsepower the unit of measurement. BHP - Brake horse power is a measure of ENGINE power (some weird tool that i don't even know about). WHP - Wheel horse power is a measure of the actual amount of power that makes it to the ground (dyno). HP - Horse Power is an insignificant term.

PMPO - peak momentary power output Acronym for peak momentary power output. This term refers to the maximum power output achieved for a speaker system under perfect conditions. ... The PMPO of a speaker is actually based on the maximum power output in a very small period of time (microseconds).
