Maybe it's just me and I'm no good at searching the forum, but I'm not finding info about testing cabinets for frequency response etc and was wondering a few things such as: 1] recommended micing practice? I have a "flat" mic for testing, but wonder what is the best way to place mic for frequency response testing? Like, three feet away on center of cabinet? What's best? 2] are there any decent free-ware rta software that don't require a degree in computer science/linux lingo to understand how to opperate? I recall trying to set one of the freeware ones up a while back and the user interface was so complex I never could figure out how to simply get some white noise out and get a response curve... 3] I keep seeing stuff like "impedance sweep" and am wondering how one can do this easily with just a computer? I suppose if I have a function generator and a bunch of other test equipment it would be easy, but I don't.... I remember BillF saying a while back that equipment to get T/S numbers for drivers was complex, but it would seem to me that with a decent mic that getting a freq repsonse graph, and using that to tune a cabinet, would be pretty easy in these days of modern computing.
