Measuring Watts what? yes Watts

[LocoStereo]

I have a Pioner sx-1050 running a pair of Infinity RS4's from the 80's. What I would like to know is if there is a way to measure wattage at the speakers using an DVOM? I know that you can buy wattage meters, I have seen one or two pop up on Ebay. I was just curious how much power I am using to push my speaks. any idears? And why is it snowing when it's April 16th? Thanks!

mcintosh sells a power/wattmeter FYI, not that expensive, and it looks really cool too

keep them spinning,

Watt meters are really not watt meters... they are volt meters but marked for the wattage at various levels.

For example, to produce 1 watt with an 8 ohm load will require 2.83v. 2 watts would require 4 volts. 50 watts would require 20 v. 100 watts would require 28.3 v. So, those levels would be marked not 2.83 or 4 or 20 or 28.3, but 1 w, 2 w, 50 w, 100 w.

It's totaly crazy! 8 inches plus on the ground and 2 inches on the northern facing side of everything:thumbsdn:

FWIW, i think you could get an accurate AC voltage reading at the speakers if you used a constant tone, then use the math to calculate watts.

But, i think most VOM's and DVM's have a slow response or too low of a sampling frequency to accurately measure the wattage of a musical signal due to the dynamic nature of music.
