Torres' Box Tuning Calculator - Updated 8/18

[Torres]

thanks! that was the main update, but then i kept thinking of other things to put in. that was hard debugging too lol. it seemed that people were using the 12-16 as a guide instead a rule of thumb. so if it was less than 12 or more than 16 than it had too little/too much port area. but now it looks like it's even worse lol.

PM me with your idea of woofer types and such. i could put in a box where you enter in your xmax and it gives a port area range for that amount if that would work for what you're thinking

That port area range on the previous version calc helped guide me. Since my Xmax is only 22mm, I went to the low side, but it was nice having it automatically correct it as I played with the dimensions of the box.

yea, kinda my thinking on it, since a lot of your kickers, alpines, rfs, and other such woofers have a lower xmax, going the full 12+sq inches of port may cause to big of problems with unloading to easily and trashing subs. Where as your dd, dc, fi, aa, sa, ssa, etc all have higher xmax and can handle the larger ports.

Torres, Ill try to think of an idea to best do it.

Maybe something with a simple drop down box that says Xmax more than 20mm Yes/No (yes being defaulted). If you select yes it does the 12-16, you select no it does a smaller range.

Ill try to go thru a bunch of brands and check specs to try and find a cut off number, because I know even on some of the lower end Fis they are 10mm less xmax than the top models.

[Captain Stupid]

Based on my REs having a 22 Xmax, I'd make the cutoff 25 or more. But that's just one man's very, very novice opinion.

me and brian (i hope he helps anyways lol) are gonna try to work something out for the xmax/port range that should be a little better than just the generic 12-16 sq inch port thing. won't be hard to add in, should be able to get it done in a night then i'll upload that version

Hey Torres. Not sure if this has been mentioned or not earlier. But I work with metric here in NZ so having the CM/MM feature is fricken amazing and I thank you so much for that. but any chance of a feature that when I enter all the box specs in CM like I would have in drawings on paper, I could then click the FT button and it converts it all to feet, (my box is 1200mm long, so if I press FT it changes it to 1200ft long lol) Just so that its easier to compare with majority of other box designs that are in FT?

Just an idea, and i know you get a lot of them. but over all this is a fucking amazing program and love using it, makes thinking up ideas so easy when you dont have to do math

[Torres]

thanks for the compliments and that is definitely a new suggestion. i would have to look into that and see how it's done. initially...i don't think it'd be too hard to do. if i can slip it in, i'll update that along with the previous one i'm gonna put back in

Torres,

Thank you so much for this program! I'm trying to build a ported box around 2.75 ft^3 turned to 33hz. I must be doing something wrong because I'm getting "Too complex to display" for my port top/bottom and port side.

What values do I need to change? Thanks.

[Torres]

that just means that your port bends and has too many dimensions to list in the tiny text box that's there. you're not technically doing anything wrong

[Torres]

hmmm....since i'm going to be doing a couple tiny updates to this....anyone think it'd be helpful/worth the time to make it multilingual? just change the names of the title boxes to spanish, german, italian, etc from a list that's selected. if not i won't really bother. *could* be more work than i am originally thinking
