I'm about half finished with some extensive testing to solve a heat issue on my Outlaw 770. Using 20 minutes of a CD and with a Fluke Mulitimeter 83 taking voltage readings on the 5 M80's and the QS8's, so far seeing interesting useage of watts per speaker for average and peaks. Will post the info if enough are interested...and I have proved my therory as to what the problem is with the 770 I think, will see if the tech agrees with me tomorrow.

Give a man a tool and enough spare time and he'll find a use for it.

I'd be interested in your results as well.

Tharkun, will those watt usage levels be accompanied by some information about SPL spikes as well?
Putting the watt usage into context with sound levels would be interesting indeed.

Speaking of which... I just deleted the .WAV file off my web server of what the psychoacoustical compression in MP3 throws away.

Still testing a few things, and yes, I have made notes of the SPL levels, mostly have bee in the 100-110 db range, and my Bengal cats seem to enjoy being in the middle of the listening area and following the sounds from speaker to speaker. lol

Oh MY, 20 minutes at a shot at 100-110db! How many cycles? Do the cats still purr? How can you tell? How can THEY tell? lol

Just kiddin'

I'd love to see the results along with a list of what listening material was used. More bass should = more power used

how are you taking current measurements? Since you do need Current to get power.

P= IxV

Or get I by voltage and resistance but you cant use the nominal impedance, or can you. I guess if you average the voltage, you can use the impedance since that is also an average of the reistance at the frequencies... Hey there ya go.. im driving myself crazy here
