Of course I could be wrong in my technical. But, I'm jammin on Hendrix right now, and it blows my purple mind, that's all that really matter's. right?
The way I think it occurs no. a more complaint would not allow for more tangential just like mbl is not tangential not in this sense too complaint. These waves would occur where it is stiffest in a sense. If all that matters is the music then go ahead and jam I wont bother you.

No, you DO bother me. If you want to get technical, that's precisely where I excell broski.😀
It's all majic sh*t I can't stand. I just made a simple *ss speaker that sounds sick, and wanted to share it with the the universe...you jumped in here with an "argument"😕 Grow up dude period...
Cant tell if trolling... I simply pointed out that an observation MAY not be correct. It also was not even directed at you. With that I am taking the higher road before it goes on longer and pollutes this good thread.
Ok, y'all...It's break time.
I wish I'd been on the Bobcat crushing cabs...was off weed-whacking at our 1/2 acre potential home site, and loading up some dumpster filler....
Oh, yeah...one of my 'honeydew' projects is to 'retire', and build a house. Now, if you feel that something like that constitutes 'retirement', please forward whatever it is that puts you in that state of mind so I can indulge as well. 😉
The short story of my life is that I seem to prone to be presented by projects such as the above with remarkable regularity by the people around me, both 'professionally' and 'socially'. I seem to have this 'knack' for being able to do the improbable with very little.
I've been waiting to be asked to do the impossible with nothing. 😉 The rant that will follow that request will be posted here in it's entirety for your amusement and education. *S*
Meanwhile. My friends....*S* Let me distract you with my observations of the tangential/horizontal issue...or, at least, how I interpret WTF is going on with an excited cone. (That sounds vaguely....*L* No, let us not wander off there....).
BTB, C...Nice looking driver, elegant and minimalist. That's what I think the potential lies...*S* Oh, and since you're playing Hendrix..."Stone Free", loud. *G*
Mags, C....in my somewhat and perhaps odd view of the physics involved with what's occurring on the cones I use a smoke ring analogy. (Yes, I smoke.) The ring expands as it travels, growing in diameter, but the ring 'hoop thickness' is growing thinner as it expands. An 'O' ring of nice stretchy rubber will do the same thing, if you could subject it to the same forces and motions, IMHO. Maximum 'excitation' (if you will) from the voice coil are occurring at the apex of the cone. At that location, the cone's stiffness is at a maximum; small diameter, minimum material, highest frequency. As the 'ring/hoop' waveform descends the cone, these 3 parameters are shifting simultaneously. The forces driving the wave down the cone are getting 'stretched out', and the wave's frequency begins to drop. Makes sense; it's having to excite more material. The force driving the wave ideally should be staying the same, but likely is loosing some of it's power to the cone material's composition. As the descent continues, the frequency has dropped to a point where the waveform is forced to transform from a tangential to a pistonic state. The material's unable to vibrate/move 'laterally' anymore; it shifts to moving vertically, echoing the movement of the voice coil's translation of that frequency.
*Whew* That almost sounds logical...but consider the source. *L*
Hey, guys. One thing that's also occurring with a smoke ring is that the 'ring' is rotating 'inward' on the column of air that created and is driving the ring away from the 'emitter'. I would bet that a similar thing is happening within the cone's thickness, although I don't have the slightest idea as to how one would verify this observation. But physical things tend to act the same way; water and air, as we experience them, seem to be different (thankfully) but they act and respond in much the same way.
The chimes hanging from your neighbor's patio...yeah, those things that go bonkers when the wind comes up....the smallest, the highest frequency. The biggest, the lowest. Subject to the material's thickness and length. The conical one's have a resonant frequency.
I'm starting to jabber at the keys...happens IRL, too...😉. As I keep returning to, there's that 'Level'/Diameter on a given cone of X thickness where that transition occurs. Above that 'L/D' plane (since it's a section of the cone's height), you've got tangential motion, but it's not all that 'big' of a motion, due to the circumference of the cone at that plane. It's exciting a large diameter, but the tangential force is weakening. It's about to 'go vertical'/pistonic.
Fondling the cone under drive is fun, but also is an interesting experiment. You can feel the tangential force change as you run your fingers down the cone. As I noted before, very 'lo-tech' eq. But as you reach the bottom of the cone, you can almost notice the transition beginning to occur. It's noticeable with the 3.5's large cone. At the base, you can feel the pistonic force on the surround. On the smaller drivers I have, there's very little vertical motion being expressed. And there's also not a lot of lower frequencies, either. On both, placing my fingers on the surrounds, adding a certain amount of 'digital damping of a physical nature', I can shift the lower response of the cones.
Anyhow...my interpretation of 'Walsh Reality', IMHO. Subject to correction, since I can misinterpret just as well as the next drone. *G*
Carry on if you must, but 'fight fair', 'K? 😉
(*L* Damn, I've written an f'n book...*whew*, I need a beer....)

Be careful... Don't say "bending wave", there is trolling software listening in...

I thought energy traveled the path of least resistance, maybe I have that wrong. Wow, that's been my prob all along...too late now anyways
That's what I'm afraid of...*L*...y'all lurking about in ambush mode.
"Shields Up!" *boop*
*L* We can call it anything we like...it's just a force, and it doesn't GAS what the reference is. As for the path of least resistance, I suspect that path is down the cone. There's a 'bell mode' response in play, it seems. Once you whack a bell, a cylinder, or any suspended object, there's a vibration induced that continues until the material dissipates that energy.
I smack my forehead, and the gook behind it soaks up that up. Hopefully the force causes the intended effect. Doesn't work all the time, but seems to make the onlooker(s) happy...😉
So, what's on the new drivers now? Can you dance to it? *G*

I've got some IRL stuff to deal with, so I'm going to be popping in and out for awhile...
Patience is a virtue, so I hear. *L*

To anybody listening in...you can make a Walsh cone out of [paper], and if you are a half-butt craftsman (like Jerry and I) it will sound...kick *sss! whether or not, it might be transvcerse or longitudial, it doesn't really matter in the end
