WinISD questions

[terifi 10+ year member]

downloaded WinISD, and filled in most of the info, however, i could not find the variables....

What does Z stand for, it wants ohm units, but what is it?

SPL?, wants decibels

PE?, wants watts

also for Xmax, and Diameter does it want Meters, b/c i am only given mm on my sheet, so i move the decimal 4 places to the right? so for xmax it should be like .001191 b/c it gives me 11.91mm?

The measurement in WInISD can be changed by clicking on it.. if it's 11.91mm, then change the required measurement by just clicking on the m, cm, mm, ft, yd, in, whatever...

Thanks, but anything about Z, SPL, or PE?

But WInISD pro is still an alpha version isn't it? I eman, it's not yet complete or something... guess I'll try to look for it right now...

Pro is still much better, even though it's a first edition ...

ah~~~~

thanks again, O wise one

z= the speaker ohm (or was that nominal ohm's)//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

SPL refers to the sensitivity of the speaker eg.: 89Db, 92Db (or was that SN/ratio or dB @1w/1m?)//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

and PE is the operating power ( was that RMS or peak)?

Jmac, please clear this up for us..//content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif hehe...

PE = Thermal Power handling

J,

about the PE... the ROckford technical data sheet states both RMS and peak for operating power (PE) and in winisd, I've always used the RMS to be safe...

what do you recommend? would it matter a great deal if these numbers change?
