Need Advice for 12" Subwoofer Small Enclosure DIY Build

Hi everyone,

Just before I start, I'm a complete noob at this. I apologize in advance if I get things wrong.

I currently have a really tall tapped horn (not sure which type exactly though) that was given to me and I really like it. I recently got an old subwoofer from my dad, so I want to build a mini tapped horn that preferably is light and small to carry around, while still being loud and getting to the low frequencies.

The old subwoofer/driver I have is a Fusion EN-SW12ES. Note there is like no documentation/specs online except here, however I'm not sure if that's accurate.

Now I have no idea if this subwoofer would be well suited in a tapped horn, but from what I understand, tapped horns are good because they get really loud. I plan to use this subwoofer for small DJ gigs (like college house parties, DJing with friends, etc.) so I want it to be loud while still being compact enough to carry around, compact and light enough that I can lift it by myself. I usually play lots of bass-heavy music, such as trap and EDM.

I've been looking at some tapped horn plans; mainly the two I was looking at was the THAM12 and CUBO12. Additionally I was looking at a MTH-30 but I think that may be too big. From what I understand, the THAM12 may be better specs-wise, but the CUBO12 is smaller, easier to build, but does really bad under 40hz.

Due to the lack of documentation on my driver, I can't really simulate different enclosures in Hornresp well (or accurately, I doubt the linked spec sheet is accurate to be honest). I also can't simulate the CUBO12, so its hard to compare the two tapped horn enclosures I was looking at.

Right now, I think the THAM12 might be the best option for me (however my decision changes literally every day 😅)

What is the best tapped horn enclosure that is small enough and can get to low (enough) frequencies? I know there isn't a good compromise, but I've been stuck researching and comparing the THAM12 and CUBO12. Or even would this be better in a non-tapped-horn enclosure?
 
With the given Spec sheet it definitely sims better in the Tham 12 instead of the MTH 30 but still a bit peaky.

This is 32V 6mm xmax excursion 8th order LR 30hz Hi Pass
Looks good in a BR - with 50 60 litres tuned to 40Hz but about 91db/W

28V 6mm xmax excursion 8th order LR 27hz Hi Pass

Finally Tham 12 vs BR at 2V (1 watt nominal @ 4R) - no filters

My thoughts are build Tham 12 & have fun - If it does not reach expectation or blows - get a new driver & carry on!

Greets!

FYI/FWIW/YMMV: Doing a comparison of T/S Vs BL, etc., specs the two sims have an identical response in HR, so normally a good indicator that the product once broken in will be < whatever its manufacturing tolerance is (QA), which historically is +/- 10%.

If size is an issue, i had a slightly similar problem, as i do not like massive speakers dominating a room, especially my 7.1 system with speakers all over the place.
I got around it by mounting my speakers on the living room wall and using the room behind the speakers, which is the kitchen, as the " enclosure "
With a nice large volume to work in the speakers can get down to earthquake level bass frequencies. Painted the speakers the same colour as the wall, and they totally disappeared. Now speakers are flush with the wall, all looks super smart and very neat, sound quality is super excellent, and i am not getting that crap coloured boxy sound that small enclosures give.

Wow thanks everyone for the feedback and analysis! Sorry I have been silent here but I was given a THAM10 w/ a Dayton UM10-22 and my expectations were exceeded. I am totally satisfied with this one. Although it is a bit on the heavy side, thats the only con I have with it.

I'm about to start my semester in college so unfortunately I couldn't have time to build my own THAM12. Hopefully on break I can go on the adventure of building that THAM12 that I was planning (or even something else, thanks Brian for the BOXPLAN excel sheets!)

Again thanks all for the feedback and analysis!
