it is a 576mm cube ? What size and parameter driver does it like? What size, shape and orientation is its throat opening? What is its usable bandwidth? - Where does the first FR dip occur? Is there a hornresp model?- I can barely move my arms anymore - but it looks simple enough to try.
(It reminds me of PWK's "LB76")

A 21" driver might be tight.
576mm / 25.4mm = 22.68in - 1.5in = 21.18in driver possibly.
Definitely an 18 will fit.

Overall Outside Diameter 21.65" = Dayton Audio PSS555-8 21".
Overall Outside Diameter 21.54" = Lavoce SAF214.50 21".
Overall Outside Diameter 21.45" = Dayton Audio HTS545HE-4 Kraken 21".
Overall Outside Diameter 21.3" = Celestion TSQ2145 21" .
Overall Outside Diameter 21.54" = B&C 21DS115 21".
Overall Outside Diameter 21.65" = Eminence NSW6021-6 21"
Looks like you need to plug some 18's into HR (use the OD function and Ap1 & Lp as the throat. Use Vtc & Atc as the rear chamber) to see which driver will give you the best performance in that enclosure.

@BP1Fanatic - I sure appreciate the input - I'm starting to run low on room in a 10x50' trailer for big projects (could use a GRS 12PT folded pipe as discussed before for LF as CUBO 12 is phat at 60 but rolls off below that point. Maybe a longer version of the 55Hz enclosure you designed - it sounds pretty good!)
Here's roughly what comes in March for my b-day - assuming I make it (one never knows")
It'll run from a Kinter 2.1 3118 amp. Left and right speaker = 3fe25-4
- 10" = GRS 10-PT (all I have laying around) in 20 liters chamber sealed box with ~370uF series capacitor.
2pi - "20 watts 8 ohms)

on the up-coming boombox - with passive highpass for 3fe25 it could double as a battery bass guitar amp. Here's an old sim of a 3fe22 for a "FAST" speaker - Kinter's 2.1 amp LF channel specs 20-180Hz (fixed) so around a 200Hz LF rolloff on 3fe22 ought to help keep excursion way down on the 3 inch speaker. 3FE25 will play pretty well w/o any highpass as my "main stereo" these days is a Kinter 2.1 amp with a pair of 3fe25-4 K3.5 cabinets with CUBO12 PYM1298/CUBO12 helper woofer.
