Oh, i see… I didn’t realize what youre talking about. And I was totally looking for something else , but the D sharp and flat E row are close to the 1/254 centimenter to inch?
Another way to look at it is that bottom row he has the golden ratio and it’s just a bitcAnother way to look at it is that bottom row E has a golden ratio it’s just round it up in that chart?
And that’s just Steps up to the 655(3.75)1310(7.5)2618(15) 5236(30)1047(60)209 (120)418 which is the (240°)
1/254:
003937007874015748031496062992--12984-25698
And in that context each one of those digits represents (metric) 10,20,40,80,160,320 which is just less than(inch) 4,8,16,32,64,128 . At 64 it begins to repeat (overlap ) the orbital set of mincers at 39(003937 in the 1/254.
so as frequencies by wave length you have 864,432,216,108,54,27. at 345.6 m/sec. But also you could make the conclusion that the 86443 choose metric again or hurtBut also you could make the conclusion the many things at 86 fours can I get you then which is going to be 24 @86400 hours worth of seconds or 1440in minutes …
And then there’s the math where the 864 is a short leg of your 30/60/90 right triangle the hypotenuse is 2x 864 as 1728 then the long leg what should be your A2 in the A2+ B2 = C2 he’s exactly the distance to earth 1496. What you can see comes up again in the numbers in centimeters but it’s not it’s abbreviated here and your numbers. But all that is potentially is another form of measure like the great many you see in that rectangle example of that granite room inside the pyramid.

Hey you can’t say that yet😀 , you didn’t look at the enclosure yet? We can forget all the silly numbers and just see how that works and ponder The idea that there’s a unique cancellation and where it’s at? And then we can worry about the silly numbers because they’ll actually be some that are relevantBelieve... believe...
The demon note add a triple tone or something?
yeah, I hope the OP OK with this. Definitely looking for some more material to add that’s relevant. it is it’s just be fairly connected as all of this talk about this rectangle in this room is the most relevant acoustic device or archaeological version of one there is?? If we figure it out because the perimeter of the base is pi

What are the capabilities of the field coil? And how is it built?
I would test it out with a range of magnetising currents and listen to what they do to the sound.
AFAIK the core should be strongly saturated. This should reduce distortion as it prevents the VC field from storing additional energy in the core. But there could be other effects at play, like air leakage or the domains aligning differently depending on the field strength, possibly resulting in some kind of sweet spot, or the harmonic balance changing...
And 6cu ft? Why not hop on Hornresp and play around with some rear loaded horn alignments? You could also play around with the BL curve and see what effect it has on response peaks there. Though there might be some overlap with tinkering with the output resistance while keeping BL steady.

As noted above, it doesn't require 6ft^3; assuming the highest voltage drive (lowest available listed Q), then optimum power-handling, with a reasonable response, is just over 106 litres, or about 3.75ft^3.
Typically, a back-loaded horn is the largest of all possible enclosure options for a given tuning, assuming a reasonable response, although to a point that depends on how you define the response & of course it's assuming the same tuning (& that all the box types can achieve the same -a horn theoretically can get lower, at the price of size).

I built a BLH for a 10" FR once, it was great. Didn't appreciate the laserbeam wide listening spot of that particular FR, and eventually the coil started rubbing and never got better despite trying to fix it, but the BLH was very nice.
Almost forgot , that 3960 (396) is equatorial radius of earth . 1080 is moon, 4320 is sun/Jupiter. 666,000mph is earths speed around sun.
The connection to the polar response of a wideband drive unit, and the mechanical failure of a voice coil going out of alignment is perhaps a little tenuous. To paraphrase the late, and very great Carl Sagan, the only influence I can think of that Jupiter could have had on that drive unit was its gravity. But the gravitational influence of a piece of dirt in the gap, or that of a suspension failure was likely to be a trifle greater. Jupiter is a lot more massive, but the mechanical failure of the suspension was a lot closer. 😉
Drooping suspension was something I had thought only happened to old old speakers from a bygone era. But then I saw it happening to a down-firing sub, which sounded better side-firing, anyway. And then I had to rotate the midwoofers that were brand new in 2003.
The soft rubber surrounds on the [really nice ceramic woofer brand] probably got too much sun, and they look like they're about to crumble like the sphinxes in the Never Ending Story, or the tiles in the Matrix.
To even think about repair, I'd first have to defeat the child-proof metal grille. None of the techniques I can think of (solvent, angle grinder, pliers) seem guaranteed.

Lol! True true, However is the details in the numbers and the perfect cancellation alignment to those numbers that hold the real uniqueness to all of this they did thaHowever is the details in the numbers and the perfect cancellation alignment to those numbers that hold the real uniqueness and significance rich nothing else produces ?

I suspect google translate is failing you as I can't make head nor tail of the above I'm afraid. However, while I agree that number-association can be entertaining (& sometimes even instructive), and that it is quite possible that Jupiter's movement in the development of our solar system had a profound influence on its current structure -it still has no direct relevance to sagging suspension or a piece of debris becoming stuck in a voice coil gap. 😉 It's a bit like saying the Big Bang is relevant to it. Well -yes, since the universe would not otherwise exist. But while profound in the most fundamental sense, and undoubtedly interesting, it's also a trifle abstract in terms of practical engineering. If I discovered a drive unit with a rubbing voice coil, my first reaction, which I admit is a little boring, would not be to ponder whether Jupiter's orbit, composition and mass were responsible. I would, instead, examine the drive unit, and (for example) remove the slip of paper a curious toddler had somehow managed to jam into the coil gap.

Nah, sorry guys, I was assuming the Title of the thread Earlier and shapes and volumes @length… and then a few things That Kappmann was referring to as I came up with quite a few things on the subject that might’ve been of interest.
I don’t think Google translate would help with that and coil gaps.

My first point as well, no toddlers available at the time, I am very uncertain whether it was dirt or sag, was unable to make it go away despite some effort, I half suspect a faulty voicecoil assembly. Did not cut it open to check before I threw it in the trash, was a AN 10" super something. Most seem happy with their purchases, Probably just got a "hangover monday" type specimen. Years ago, water under the bridge.
