Cabinets suitable for PWX 16/800 [Help]

Hi everyone,

Hope you all are well.
We have a pair of PWX 18/600, for specs:  jb-systems.eu/fileuploader/download/down...FFile-1438350390.pdf

We plan to extend to 4 subs, potentially using these drivers. Now we need to find cabinets which I can build for them and are suitable, preferably large from what I can understand that works best for them.
Potential designs I am looking at:

• WSX
• 186 Horn
• Hog Scoop
• MHB 4818

I am learning to test on Hornresp in the meanwhile which I am new at. Sorry if the question is ignorant or repetitive, but I could not find much information searching on forums and sites for these drivers.
Any help is appreciated that can lead me towards a design we can use. Thank you in advance

Also potential design:
Mogale Super Scooper
