Can't find a good enclosure frequency response curve calculator

[QUOTE="tb30570, post: 8477179, member: 617027"] The last time I build a subwoofer enclosure (for home not audio not car), I was using a website where I could input the Thiele Small parameters, enclosure size, port dimensions of my choosing and it the website would plot a frequency response curve. It was really helpful for not only designing an enclosure but for choosing which subwoofer to purchase based on what output characteristics I was interested in. I tried searching for the same website I used last time and have had no luck. I did find some websites, but they are pretty limited. This is the only calculator I could find that plots a curve. It doesn't allow an infinitely variable input of enclosure size for a ported enclosure. It gives you three options (small/medium/large). The horizontal axis is labeled very coarsely too (10hz,100hz,1000hz). I'd rather see 10hz increments from 10hz to 100hz. [URL="http://www.ajdesigner.com/fl_subwoofer/subwoofer.php"]Subwoofer Box Enclosure Design Calculator - Sealed Ported Bandpass Closed Vented[/URL] All the other calculators I found don't plot a frequency curve. They simply output f3 and fb which isn't nearly as meaningful to me as a plotted curve. Is there a better website out there or is this information only available on licensed software? [/QUOTE]
