Torres' Box Tuning Calculator - Updated 8/18

[waxmyjmy]

How would a box appear if you use height 1 and 2 width and depth 1 and 2 I am trying to build a box for my truck behind the seat the back wall being flush with wall the top being a 90% off of back to the front and the front of box nearest seat would be slanted as the seat goes to the floor. The sub itself mounted on bottom would be at an angle as well so I could get the mounting depth I need otherwise it just doesn't work....

Feel free to pm me for a drawing I have of box I'm just wondering how to calculate on Torres thanks for any help

there's links to pictures demonstrating examples of each type in the help window.

So I just downloaded the newest version on my new laptop and it is showing different specs than the old version

old:

new:

It looks like everything is the same except for port volume, so which one is correct? This is the specs for the wall currently in my truck btw

^^ Same thing happened to me

The true port displacement can be found via sketchup I have done extensive tests on both versions (more on the older one), both versions miscalculate port displacement somewhat in some situations by a larger margin than others. The older version had a smaller error than the new one in the situations I tested.

I think a solution to all of this is to add in a part to this app where you can manually put in your port displacement, this would allow for 100% accurate calculations, because if you route the port differently then the app it will all be off, the port displacement changes the tuning, and the inner box area, which will throw off all your calculations, I am having this issue now, so I am using winISD and torres calc to try and get this figured out, the port displacement is much higher in torres then it really takes up inside the box, which I can't figure it out, I have been manually crunching all these numbers

Same here, I use torres to ballpark then go to sketchup and check all the math. Then i put the actual net volume and port dimensions back into torres to check tuning. I'm not bashing This calculator at all, great program. It's a very nice tool that without it would make designed my enclosures a lot harder.

yea exactly, its just that its impossible for a program to guess how you are going to lay out the port, which changes the tuning and inner volume, not the programers fault, its just a part of designing a box, if you doing a port that has no common walls and doesnt curve then it cacluates it right, but turns and more then one side it starts getting off, like I said if we could put in the port area manually it would fix all this, or you can just use the program differently

You could actually do that the way the calculator is right now, just use the bracing displacement field:

Number to set the bracing displacement field = your calculated port displacement + actual bracing displacement - port displacement Torres shows.

Problem is that this is a lot of work.

yea, I was able to do it, I just figured out what I wanted for net box area, put that in, and then whatever I did for the port I made the calc say it was external -.75 for box thickness, but you can just put 100 in external, and it calculates it with the port length - .75 for the wall, so it works out as no port on the inside , and that gave me the same exact tuning as winISD and the12volt.com, just would be nice to have that option in there
