Well, both ours meet it, though admittedly it wasn't a comparison consideration.................
OK, here's a comparison of my TH/TTL (150 L) and Max's C Cram (233.83 L) @ 1 kW, so factoring in the box Vb difference and the main difference is a ~ +6 dB/80 Hz 'one note' peak due primarily to its extra folding, tapering, so if size, simple construction is (one of) the primary design goal(s), seems like 'simple is as simple does'

i guess you don’t understand what we are attempting to show you.
theres more to this than what is otherwise being considered. look at parallel qw resonators split at exactly 3:1, or look at ‘paraflex’ or look at tapped pipes or offset driver entry Tapped pipes, or ?
Maybe BP1 can explain this better than myself? , I instead observe it(pics are a thousand words) in order to truly understand. the sim shows things are screwed up in the same way if you LOOK….

Ack! Missing new threads caught me out again! I was responding to Max's post.
I model in feet. I usually keep the horn paths in the 10-12 feet range.
10 feet horns are the sweet spot. That length gets you down to 25 hertz. I'm a basshead and like DJ Magic Mike type tracks. Remember, the lowest frequency played on an 88 key piano is 27.5 hertz. 50 hertz BASS bins are not SUBwoofers.
10 feet = 120 inches = 304.80 centimeters.
You can have four 30 inch tall segments or double fold.
You can have three 40 inch tall segments (tri-fold?).
You can have two 60 inch tall segments or single fold.
For all you metric folks, notice all the 10 based numbers!

I like the piano refefence BP👍🏼
30 hz with ddx12 is a joke right? In a MLTL indoors maybe? or a huge ROAR. Those are awesome/fun in a car With that driver!
but not as a PA speaker. it won’t be ‘loud’ enough ?
I don’t know, but after a few of things in a car with those, they are extremely loud if you tune them up high(40hz or so) after that, it needs help.
