Sorry but it is not going to happen, sealed box , fully stuffed with fibreglass and polyfill 50/50. 105dB, Fb 53Hz and F6 24Hz.

Well, without a known Xmax it's hard to say how much 'earth shaking' bass it may be capable of, but for sure your two suggestions are only going to potentially give you some upper bass/lower mid-bass 'slam' of dubious SQ.

For 'earth shaking' bass (sub/LF), a TH sim looks good if there's enough Xmax, but the trade-off is a more complex to lay out/build ~404 L net Vb, though if corner loaded per the sim, then it can be made tall to minimize its 'footprint'.

Anyway, assuming a modest ~7 mm Xmax/100 W it should in theory have no problem reaching DD/DTD/THX reference with a bit of room gain combined with some damping and a 60-80 Hz XO depending on slope order to deal with the over emphasized HF 'hash':

hi

moondog

For ported, you could try 2 cubes tuned to 30Hz

I just used a free downloadable prgrame from Jeff Bagby, to give reasonable reults without a very big peak in response needed a huge box, Imay have made an unreasonable assumption that you were after clean smooth bass, personally I find the sound quality of high "Q:" drivers much better in sealed boxes.
Any box with a big hump has what I would call "one note bass" the sort that may emphasize the kick drum for instance, this may be good for dance muisc but not so good for classical European instruments where the bass notes from harps, double bass/cellos and typani are in the 40s,
Sorry if I sounded a little emphatic, of course you may do whatever you wish and make the box to suit your needs.
It is, after all, just my opinion
