Good question! The ported do have the edge in TR I think around port turn (in the comparisons I've done), even with the FR on the sealed sub raised up to match the ported sub down low, around 15-10hz port tune for example. But the differences between the TR of the two aren't as noticeable if Crowsons are in the mix. And especially not if you can run a sealed sub in the mix with the drivers right up close behind you. Total game changer even in a large room and can make you rethink if one should go the ported or sealed route.
The other day in one of the other threads (The Bass EQ thread), I was doing some testing in a scene in a movie called 'IT', (with BEQ of course from the Bass EQ thread
) where there is a really strong 12hz frequency that goes on for about 15-20 seconds. I run a few sealed 18's right behind my seats, as well as Crowson MA's. I was playing around having a lot fun on this for a while testing the differences in TR feel etc between each of them.
Surprisingly, the 2 VNF sealed subs (2 FF in the mix as well), were giving me about the exact same wobble feel and intensity as the Crowson MA's (which was way cool because Crowsons can bring on the TR wobble down this low and I had them cranked up pretty good). Without the Pressure and weight of course on the MA's, but can kind of trick you into thinking your getting a little bit down this low. I've been a long time user of VNF subs, (ported and sealed) and love what each can deliver like this in terms of TR. This comparison really drove home just how capable a sealed sub (at least when close behind) can be for TR down into the very deep areas of ULF. As much as a ported sub positioned this way around it's port tune? Probably not quite as much with matching FRs, but still great and probably a lot smaller foot print on the sealed cab that will take up less space. Combined with MA's (even if only farfield, but especially nearfield) it can be pretty crazy and not so much a big deal in the overall TR department if sealed is what one wants and likes.
As far as weight and pressure like Imureh was saying, so far I've found them to be pretty similar and is needed to go with the TR for a more realistic experience. But yeah like he was saying also, the FV's ported subs are pretty darn accurate. I've got the FV15HP and reminds me a lot of how my sealed subs sound, with a bit more thickness down low on the sealed but similar kind of detail and articulation.
If your a TR lover, I don't think you can go wrong with either if Crowsons are in the mix, and especially if you like using VNF (very near field) as well and closes the TR differences between the two pretty well (even with ported or sealed right behind you). The combo can probably give most people all the TR they care to have. I'm not trying to turn this into a VNF post, but wanted to mention it as its fair game if one is chasing TR and trying to decide if sealed or ported would better suit them, and not just in the TR department.
If one loves TR though and cant for whatever reason or doesn't won't to have Crowon MA's or VNF subs behind you in the mix, then ported is probably the better route to go if 'only' Farfield sub positions will be used.
Again, just my 2 cents and what I've found messing with it all.
