L-shaped box, where's the port stop?
If a slot port/box is in an L shape than where does the port stop? The port width and box NET depth being equal. To answer the question... is a port only considered a port when the NET space is either larger or smaller and/or a different shape?

If your vent area gets too large then you don't have a tuned port anymore. At best you have a transmission line enclosure. At worst you have a box with a big hole in it.
Bose makes/made a commercial bass cabinet like this that is/was a 10 or 12 inch driver in a 10" diameter pipe 10feet or so long with the woofer about 3 feet into it.
Spend a little time with a calculator and vent sizing program and you'll see how it works.

Not to mention most people in the younger generation wouldnt know how to figure out the equation.

I asked because I know who JunkInTheTrunk is and he should be hooked up. I believe he was being sarcastic.
The real caveat of any software or equations is if the user actually understands what they are doing. Designing a box and designing a box that WORKS are very different tasks..
