i tried to download kings spreadsheet but i think he took it offline, so i didn't model it. i put the port in the rear just in case i wanted to plug the current one and relocate it.

already forgot the cabinet dimensions Razz
i think it's 34" tall.

do you have a copy of the spreadsheet?

I do have a copy of the MJK spreadsheets, as I purchased a commercial license. It wouldn't be cool for me to give it out but I am sure Martin would send you a copy for this project if you asked him. I remember he took down the shareware stuff because he was getting miffed at commercial designers using his code and not paying license fees. But I seem to recall that he put it back up. At any rate, I suggest writing an E-Mail to him and telling him what you're wanting to do. Point to this thread if you want to. Martin is a real approachable guy and I'll bet he'd be happy to let you use his software for non-commercial DIY stuff.

actually. i can get a mic from my brother.
is there computer software that i can use to measure the response curve with?
is there a cd i can get that has a sweep so i could measure from 20-20k hz...

Try Speaker Workshop. It's pretty good and it's free. There is a Panasonic capsule microphone amp schematic and tips in the Measurement forum that can help get you started. There's also a Speaker Workshop support forum on their site.
