Port location for enclosure with 3 subs

[tyma1026]

Ok so I have an enclosure that fits 3 subs.  The subs are up and the port is back.

The port is right in the middle between two of the subs and the 3rd sub can be seen by looking in to the port, right in the middle.

What effects would the 3rd sub and the port being in the middle have.

When you have 3 subs you do something like this:

That's what I was thinking. 

So what happens if say the middle sub was on the rear of the baffle, and the port was in the middle.  Attaching a very poor drawing to show what I mean 🤣

Not sure how to explain it but is the 3rd sub able to perform the way it should in this or would it be ineffective?

Uneven loading is what can happen if the sub in question is too close to the internal end of the port.

Thanks.  Was looking at building a box like the one I drew above but was told it was bad.  I thought it would be ok since it was still in the enclosure but I see I was wrong.  But yeah, just wanted to understand why it was bad.  I'm gonna search the forum to learn about loading issues.  Thanks again

No I no longer have them I ended up selling them to do a backseat delete to run 2 15s in my crew Silverado
