LOL!
And how many listeners?
2? -That's 4 24" per person
The Norwegian Oil Sheikhs have a great time
Cheers
One listener
The idea Is So smooth frequency response as possible without EQ
This will be used from 10 to 60 Hz
And this is the result

OK, your box isn't a high aspect ratio, so you can put the vent wherever convenient.
The way a vented alignment works is that the cab has an air mass 'plug' and the vent has one of its own that vibrates at its open pipe fundamental/harmonics based on its acoustic length [which is a bit longer than the vent's physical length] and how much the cab's air mass modulates it: Resonances of open air columns
From this I assume there's not only no vent cooling of the cab/driver, but the cab's greater air mass probably cools the vent's somewhat unless it's quite large, though never seen any thermal tests to confirm.
When using one or more of the cab's panels for a vent wall, its pipe end correction is greater, shortening the vent more than what a program typically uses, so will be tuned lower than predicted if not accounted for [see attached].

This paper has a lot of good port information :
Maximizing Performance from Loudspeaker Ports

An upper and lower port reduced voice coil temperature by around 10 F degrees compared to a single port.
Below are the thermal aspects of port cooling with various configurations. Of interest, though turbulent ports are worst for LF output, they reduce temperature the most compared to a sealed cabinet.

So your saying that using my dimensions of 28 x 28 x 39h=17.69cft is plenty for cooling vc
Also if using bottom panel to create the vent as In k=2.227 picture that the vent should be shortened for correction. .
So how do we get the correct h w l of the vent for 32hz tuning ...if thats optimum
My phone could not open the pdf

Interesting, not a whole lot of power!
I use both ucd2k oen & ucd700 oem.
I'm happy with them apart from the fact that negative rail just blew on 2 of each and that they have a huge loss in idle power for my (mobile) use (35W/15W for 2k/700)
I wonder why you don't use ucd2k for two reasons.
I read on a forum about one who preferred the sound of 2k from 700 and changed.
And on the other hand it's closer to rated power 1600W@8ohms.
Then you can have a great dub-party
-Just joking, but still looots of headroom.
As far as i recall 2k costs 50% or less more than 700
Indeed they are rather massive, the magnet looks almost tiny on them, yet they are the biggest neo magnets I have seen
They are large enough to actually produce bass on their own, no enclosure required, this is how I use them at the moment, living in an apartment and all, but I understand that this is not the way they should be used.

I think UcD700LZ OEM is a better module
This is a subb for a hi-fi setup, not a disco.
Quality over quantity. And I do not think the housing structure manages more vibrations
