I watched 123toid’s videos on winISD so I thought I’d give it a try. I added my woofer (10″ RS270P-8A). I picked vented and cheby-chev (however you say it).
The program came up with a tuning frequency of 25Hz with a box volume of 1.65 CuFt. I’m clueless as to what I’m looking for on the graph. I noticed the more I increase box volume the further the line goes to the Left before it starts to roll down hill. If the box (volume) gets to big the line on the graph forms a hump.
So I’m assuming I want the line on the graph to be as flat as possible,with no humps? I made the volume 2CuFt and tuning frequency 28Hz. (See the the included picture). What is this graph telling me? Its not a whole lot different than the graph at 1.65CuFt at 25Hz. Do I also want my tuning frequency to not be lower than -3db on the graph?
