Subwoofer box volume and port size?

Originally i was to get a Dayton driver but no one has it in stock in Europe so the store offered me a Scanspeak 26W/4558T00 Discovery for the same price but now im back to square one. I do have an idea that the internal volume would be between 55-60 Liters and the port is a 10cm diameter and 50cm long. Wouldnt you guys say thats a good way to go?

Optimal vented box for 10" Dayton sub

Im about to buy a Dayton audio 10" subwoofer. Dayton Audio - RSS265HF-4 10" Reference HF Subwoofer 4 Ohm
I was just wondering what internal volume and port size is recommended for this driver. It for my home cinema and they are supposed to complement my Polk R200 and the rest ofc. Daytons site says optimum case size for a vented box 1.5 ft.³ but it sounds rather small or is it just me? Also i dont have good enough experience and tools to build the vent so i rather just go with a round pipe.

Here in Denmark we have a supposedly DIY speaker guru called Troels Graversen. I must say his entire house is filled with speakers and components. And he does have the experience. Bought a pair of bookshelves from him and they sounded amazing.

But in an article of his he mentions that one cannot simply calculate a crossover by just knowing case volume and ports and drivers. Because like he says you need some special listening equipment with a microphone because the front of the speaker as in distance from the different drivers and also the size of the front and so on.
Is this true or is this just for high end builders. I just assume normal people like me couldnt tell the difference.

I have 2 old Dynaudio 15 W-75 8 ohm drivers and a Dynaudio tweeter. But i dont know how big the box should be or where to calculate it. Also it would be ideal if it also could calculate the stats on the crossover components. I have a hard time figuring out how to use some of the online tools. I can only figure out how to add one driver in these online tools like speakerboxlite.com
I scrapped the drivers from my old bookshelf speakers and my current center is a cheap not so good sounding Dali. These Dynaudio drivers will do a much better job im sure.
