Well it seemed like a lot of noobs like me were struggle on port calc. and were starting pretty retarded posts (like me! LOL). I guess I got a little over excited since I need one so bad and I couldnt find one //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif. Either way its a great site //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

BTW, I like ur avatar!!

establish a volume, establish a port area, find your port length, then get the port volume, add it to your NET volume, also add your speaker diplacement, get your deminsions.

Why is xMax included? Generic displacement figure?

All you had to do was ask. And I could have posted that a long time ago...

i can see why it took him awhile to find that. most of the time when someone asks about finding port length and what not, you get 11 replies saying i'll make you box plans for $10 //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

Why, you need some? I'll make them for $8 //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Just kidding. Seriously, just kidding. Please do not PM me for box plans. But the stupid thing about it is that 10 of those 11 replys are from people who just learned how to even calculate port length a month ago, and 2 months ago didn't even know what a ported box was.

Anyways....I'm old school and prefer to do it by hand.

http://www.diysubwoofers.org/prt/ - the "ported.xls" program is pretty nice.

I do all my calculations by hand...

Although Im sure none of you care

 

[bcarpenterfhl 10+ year member]

we don't. and personally, if i were to buy box plans from someone, i'd rather them use some sort of calculator, and not have to worry about the vulnerability of human error.

 

[1990RANGER 10+ year member]

Well, whether u find it useful or not the threads posted (unless a mod. removes it of course). But I'm sure at least one person will find it useful and not have to post some retarded "how big should by port be" question.

And I did do my calculations (with reference to george's post) by hand but I the answer I got didnt make sense. So I redid it with the new equations and it all finally works out //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif! Anyone can pay $5-10 for plans, I just prefer to learn all this stuff and do it myself.
