What Calculator is Most Accurate

[dan5505 10+ year member]

So i designed a box, and put the specs into three different online calculators: the one on Re's website, subwoofertools, and the one on carstereo.com. I got three very different port lengths. They varied by almost 10 inches. has anyone tested them to see which one is accurate?

try WinISD...

i have, they all seem to vary

i tried calculating it out by hand just for the hell of it also. Do you think winisd is the most accurate then?

Personally WinISD has never done wrong by me and my calculations...try it

k, all of these were @ 32 Hz port lengths are

Winisd: 50.00 in

carstereo.com: 49.25

subwoofertools: 51.5

RE: 37.125

by hand: 51.58

K, so i guess most of them are consistenly around 50, but the Re calculator is way off.

The differences that you got with the different calculators aren't nearly enough to worry about (except the Re one and I've heard that it is crap). Placing the enclosure in the car is going to have a more profound effect on the actual tuning than the 2% difference in port length that you're looking at between all the calculators.

If used correctly, your brain will be the most accurate calculator.

I have always used Termpro and has seemed to be very accurate.

any sites with all the math equations to design an enclosure correctly?

i would like to try to do one enclosure that actually works for me this time

winisd is off by like .3 or some shit from my calculations by hand. its the most accurate by far IMO
