I saw the other post regarding box design calculations, when I remembered that I believe I once saw an electrical method to determine what the Fb of an enclosure was, with a speaker in it. In otherwords, determine what an enclosure is tuned to with it's driver in place. I think it involved a sweep generator, but was wondering if anyone else had seen or heard of this and if so what the procedure was or a link to it.

Thanks, I knew I'd seen it somewhere, just couldn't remember where.

Yeah, I've lost that link more than once. It sure is nice to be able to link to stuff on the WWW instead of constantly having to type it all in! A lot of people have done a lot of really cool stuff with web pages and it's quite nice to be able to reference it all. :yes:
