BTC Port width

I am using the box tune calculater app. Trying to build a box for two 12 p3s. So I put the dimensions in the calculater. I also figured out the port width. I wanted to do the port on the side so with whatever they give me for port width is that what I use or do I double it? If I keep it in the middle it stays the same cause there is two different chambers correct? I am struggling with this. First box build didnt turn out as planned.

Could you give us a picture? I'm having a hard time visualizing what you are asking.

Post it to an image hosting site like Photobucket. One it's uploaded to the image hosting site, copy the IMG tag and paste it here in a text box.

Im not the one you want to try to troll. Just a fyi for you.

If I understand you correctly you just need to design your box in BTC for your both your p3s.. if you have the propor port area your tuning should be ok

Got it all squared away. Built it today.

thanks guys

How does it sound?

IMO as long as you can give the subs ambel amount of airspace matched with the proper port area... It's a combination of many things that make a good sounding sub box..

The width and height of a port don't have to be exact numbers as long as the total area is good in relation to subwoofers Xmax and cone area
