question on this port/enclosure design

[cx-7heaven 10+ year member]

Ok, I am building some home speakers with a ported 15 inch sub in the side. It is seperated from all the other drivers by an internal baffle. When you look at the below pic, you will see the port entrance. Due to the port length that I want, I have to do a turnaround. The entrance for the port will be approx 6.5 inches from the back wall of the main box. My question is, will the upper part of the enclosure act as a port, or will it act as enclosure dut to it being larger than the port itself?

Thanks for any help

Could essentially act as a port. Most people would consider it chamber and the performance balance may be relatively close though measurable. Should have just zigzagged it up and down.

Should have just zigzagged it up and down.

This is what I was going to suggest as well.

I can still go up and down, what you see there is just stood together, not glued. Good idea BTW, I may very well do that.
