I was wondering about the voltage applied to the K-Horn etc. as input and outputs get toward various listed maximums. I'm not sure whether these are voltages applied to the components in the crossovers. It is interesting that max continuous acoustic output requires 40 watts input.
A spreadsheet in a .zip file is attached for your consideration. I think a spreadsheet is supposed to not be posted in its native form under forum rules. It is protected but not password locked. So you can fool with it if you like. In Excel you go to the home tab and then to format. There you will see the option to protect-unprotect the sheet. Also there is the option to lock and unlock cells. When a cell is locked and the sheet is protected, it can not be altered. All you have to do is unprotect the sheet. Probable the popular open office spreadsheets can work with it, but I haven't tried.
