A tube port of any size is not always practical especially in smaller enclosures but that doesn't mean porting can't be done using, for example, a slotted port built into the cabinet's internal structure.

These ports are usually the same width as the front or rear baffle, tuning is done by varying the height of the slot and the thickness of the baffle and size of internal braces provide depth. Many high-end bookshelf kits use such ports and more than a few large speakers as well. It's too costly for mass-produced cabinets but not much more work for DIY'ers, and it makes for a studier box.

and I'm guessing that isobaric only works for subwoofers and not particularly good for the high ends.. maybe I will mount my subs like this and use a stand alone tweeter.. usually tweeters don't need a big volume right? maybe I can just place one on top like something sticking out?
I built my first succesful iso (clamshell design)
I am using 2 MTX 5500 12" subs in a 3.5 cubic sealed box
Win isd comes back with "down 9.75 db 20-100 hz"
I mounted the drivers on top of the cabinet and put it in in cornor .
It goes real good !
