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.

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.
Here you go!
8 foot TQWP (straight flare tapped horn or Tapped Quarter Wave Pipe or Tube).
26.25" high x 14" wide x 27.75" deep.

Way Cool !!! - it should rock on some organ pedals. Do you think 1/2" could be used for the side panels - maybe even the internal panels to wave on weight ?? - THANK YOU VERY MUCH ! !

off on a tangent - what ways would you do a bass guitar cabinet? - I have a little K10, ` 80Hz cutoff - sounds fine for some genre as I believe historically and now that a lot of "tone" lies in the overtones. Bass guitar pickups seem to matter - I've a pair of Fleor alnico 5 neck p-ups in a Glarry cheap Jazz bass the E string is weak. (Glarry uses the neck profile cavity in both pup positions so a bridge pickup won't fit in the bridge position) In contrast
I've a 30" scale Glarry bass which I installed a WAAAH alnico 5 copy of the 1951 Fender Precision Bass (later ~72 Telecaster bass) pickup - its very dynamic and thick sounding on the E string notes. A really good bass on the cheap. When I can afford $2025 I'll have to look for another jazz bass pickup as those Fleor are weak (wich I had an inductabce meter)
It would be interesting to see the harmonics of bass guitar pickups compared to eeach other to get an idea of what's happening.
I think some coupled cavity /high tuned BP can be good for bass guitar vs reflex.
50 years ago I had for horn loading - first a Traynor folded horn - about CV B36 size with one 18 Goodmans - it rattled (regrettably I returned it instead of looking inside - but it was new) then a 16 cubic foot Peavey with 1-18 CV and perhaps a 4 foot 1/4 wave path and guessing 60-350Hz response (?) Acooustic's 361 was popular - I had the 360/361 combo for a rew weeks but nev er took it out to play nor got to evealuate it - for fun I'd love top play thorugh a 15 w-bin with an 8" cone driven horn on top carrying the overtones

If you brace the enclosure well enough, then you might be able to get away with 1/2" in stock.
I'm lazy. I'm only into building subwoofers. For >80hz, I'm happy with my cheap pro audio 2 ways.
You really have a lot of freedom for an 80hz kick bin. Have you checked out speakerplans.com? They are really big into kick bins.
Hilarious, I did a Google search on 80hz kick bin and speakerplans.com was the 1st site to pop up.
hey BP1Fanatic - how about a 1/3 wave "Karlson" with angled-up baffle for a 12"speaker? Say tuned ~42Hz - or for more fun 50-60Hz with some positive flare and laid back baffle? That's not done IIRIC (other than Moray James little K for fullrange)
1/4 wave - would be nice to minimize a dip- - dunno if the K-aperture would make things worse - "maybe" ;^)
