Default Power sharing in 3-ways

... people often ask about this....so....

a book I have on PA speakers gives a short table of very approximate values of power above certain frequencies.

What I did was to try to fit those values to a frequency v percent curve (was NOT easy) the result was then turned into a very simple spreadsheet. (Excel 2000)

This spreadsheet is available for download from the first page of my web site.

I stress, it ONLY give a very rough estimate , and only for NORMAL music, but maybe some will find it useful anyway !!!

ps: for 2-way, just entre the same frequency twice

Oh, man...another nifty utility obstructed by Excel-dependence! (I mean: Thanks for the effort.)

Does your data coincide with this chart, found on Rod Elliot's ESP site? http://www.sound.westhost.com/lrp-f71.gif

Thanks, Andy

I had to hunt all over for this info, even though it seems to be a very important design consideration (especially since I became a full-fledged multi-amp lunatic).
