Default Port Length vs. Physical Port Length

I'm lost on how long the wall in red needs to be to give me 36" of port length...

Torres says I need 33.75" of physical port length what exactly does that mean. I'm confused as to how the bend will effect the length of the port...

Help?!?

can you put the port on the side going vertical? like 11x 4 and 27 inch long? 1.5" X 25.5 seems offly narrow. also 28hz tuning is way to low. im tuned at 33hz and kille 27 hz all day. you might run into some noise issues. esp since its so long. maybe someone with more knowledge can chime in

It gives me almost 13" of port area per foot which is enough according the the general rule of 12-16" per foot. Albeit on the lower end but it's for a single 15" running on 500w and maybe in the future 800w...

yeah your port area is OK but your port ratio is 17:1 ive heard that 8:1 is pushing it before you run into issues. 11x4 port is 2.75:1 ratio and its more port area

I was really hoping to get something that had the port along the bottom... Maybe if I make the width not as wide as possible...

The physical port length is just the length of wood, since ur port bends, its just measured along the port in stead of manually measuring inside the middle of the port following in the bend, if u dont get it then i can draw a pic, im just dropping a duece right now
