I love this box building program, but.... ?

http://www.reaudio.com/speaker_box/LPort_Box_Calc.html

but I have one question about it.

Try punching in a smaller "top depth" measurement, and a longer "bottom depth" (as if you were designing a slanted faced enclosure) {this would be best for my vehicle}
Now, obviously the vent has a shorter distance at the top, and a longer distance at the bottom. Hmmmm. This seems kind of whacky to me.... like it might mess up the tuning somehow.
When you read down below, it seems they are measuring the longest distance to give you the total port length... But doesn't air pressure take the path of least resistance (the shorter path) ? ...or is that just electrical current flow ?

Well, I'd assume that somebody has tested this program to confirm the results.....

Your thoughts ?

Thank you,

Well that's a shame....

....because IMPO, this is how a box building program should look / work.

Of course performance graphs are cool too. But this is the type of program that just makes sense to me.

Thanks though,

Hey aznboi3644.....

I've been contemplating what you said about the accuracy of the REaudio box builder.....

I mean, I can see maybe where if ones construction were off just a touch, (like with the square port especially) that it could throw off the predicted results.... maybe a lot.
But it seems to me that with any of these programs, they should just be following mathematical formulas, which is basically "exact". Of course if the person who set up the box builder made a mistake, it would be wrong.... and probably not "a little wrong" or "inaccuate", but rather, so wrong that it wouldn't even start to work (like to where it would tell you your port should be 339 inches long.... or .039 inches long) and it would be straightened out before ever making it to RE's website.

I'm not a mathematician, but I know that's all these programs are. Still not sure why this program would not be as accurate as any other. Hmmmm.

Peace,
Fish
