Need Help Calculating a Non-Rectangular Port


Herokight

Recommended Posts

I have an idea for a cool port I haven't seen done before, but I can't seem to get an accurate calculation on the tuning.

Here's the dimensions:

Got it fitted onto a baffle the way I would want it:

Did my math on the area of it, threw that into torres and got this as the tuning frequency:

Decided to try and move the decimal over one out of curiosity, and came up with same area but different tuning:

Is there any way to accurately find the tuning for this BEFORE I build the box? The plan would be 6 Mayhem 15s. I hope it's enough port area, because I think it's a pretty boss idea. I've never seen it before, and I think I see why. So much easier to calculate a rectangular port.

Hit up noobstastic I think he also goes by noobondroid same person different names

Not sure on the spelling if it's correct

He did this wall similar to what you want

Ah.... I remembered seeing that wall, but I couldn't remember his name.

If you are using sketchup, just select the area, right click ->area-->selection, or something like that. You will see it. Simple

Tried that, and believe it or not the area from sketchup and the are I got using a calculator were way different. Even did my math twice and got the same thing. Kinda weird...

i get 188.4 sq inches

edit:

when i do it on paper i get the same.

7 11/16+ 10

(7.6875 + 10) / 2 * 5 = 44.xxx

44.xxx X 2 + (10 X 10) = 188.xxx

i just put x's for the decimals, i'm lazy

Still saying something different. I didn't know i decimal place could change so much.
