Torres' Box Tuning Calculator - Updated 8/18

[blbl84]

ı couldnt get upper part but here is the dimensions

height :15

width : 35

depth : 28

according to the my calculations gross vol should be 6.94 and por disp is about 2.3 ft3

are you in a country that uses metric by default?

I remember some weird bug with non-imperial systems causing issues when using torres and using imperial.

i ask because you have commas in your numbers which is an indicator of non imperial, here in the states we uses periods for decimal points.

similar issue, i think it might be some issue with .net framework, but i dont know for sure.

[blbl84]

ı update net framework but problem stil continue

[Jessica]

i dont think it will matter, have you tried to just switch to metric and see if you get more accurate results?

[blbl84]

yes ı tried , this time it shows gross volume accurate but port disp is about same , ıt shows port disp like 28 litres: 1 ft3 , 56 litres : 2 ft3 but still ı cant see remainder part...ı designed a box that port disp is about 42.5 litres (1.5 ft3 ) but it shows as 28 litres (1 ft3 ) .....strange

I'm trying to make a 2.5ft^3 box tuned at 33Hz - 34Hz.

Box 1 (33Hz):

Box 2 (34Hz):

In box 1 I adjusted until Gross Volume was 2.5, and in box 2 I adjusted until Net Volume was 2.5. Which one is correct?

Also, is the Physical Port Length the length of the port wall on the inside of the box?

Does the correct version of the box look good?

I'm trying to make a 2.5ft^3 box tuned at 33Hz.

Here is what I came up with:

My questions are:

Do I make it so the Gross Volume is set to 2.5ft^3, or the Net Volume?

Is the Physical Port Length the length of the port wall on the inside of the box?

u want the net volume to be 2.5 also with a port that small youre going to get port noise so make the port more like 2.5-3"

Thanks man. I fixed it up. How does this look?

I made the box in AutoCAD. I read your port length explanation several times, but I'm still confused about what it means. I made the inside port wall length 28.25" as I entered into Torres. Is this correct?

.75" + 13.5" + .75" + 13.25" = 28.25"
