here's one I'M PROUD OF... made it four years ago.......carbon fiber

Ah, a dobro...yes, I know the names of 'ax types'. *L*
Used to be around musicians, garage bands, that sort of thing back in the 'blurred' old days... 😉 Never got to be a player of anything, didn't have that sort of muscle memory. But it broadened my grasp of sound and the reproduction of same. Personal musical taste is all over the board. I like bits 'n bytes of nearly all genres...
We've gone to the symphony one weekend, next week Garbage. Best percussion line I've personally experienced was the Blue Man Group live; you could have churned butter in the front rows. Jazz harp (not harmonicas, classical harps...yeah, the things with all those strings) is a wonder to hear, great fun. Trance, dance, chance....my playlist is pretty atypical.
Makes for a good 'break-in' of a new speaker, IMHO. Subject it to Anything. If there's flaws, it'll be noticed at some point. *G*
Try piano on your 'newbies'....mine LOVE piano. It may be a artifact of the alum cones, but the harmonics come through sweet. And I'm a real sucker for a well-miked piano.
We all have our weaknesses...😉

Re #441 pic...."and if it doesn't work, it can always be a vase for flowers..." *LOL*
Now, that's pretty large. You don't run the AC behind it when it's operating, right? 😉
OK, the 'hard' question: Does it work Well? It would seem without some termination at the base that it work exhibit some sort of 'strangeness'. It would be interesting to subject it to a strobe to see what low frequencies do to the base edge....see what sort of 'flexion' is going on, say @ 40hz.

"High-end adult paper mache..." I like that, Mags. It's occurred to me that making one's own cones is possible. I've seen live a demo of art paper making, creating the pulp and forming sheets of whatever thickness out of nearly whatever one can turn into a pulp. All you need is the form, and a press to purge the water out of the mix in the form. Regular speaker paper cones are made essentially in that fashion...
Not your 'kitchen table' sort of activity, but...in the garage, hmmm...
"What goes on in the garage....should maybe Stay in the garage..." *L*

It sounded great! Over 90dB. The best thing is that you could step on it and it would pop back without harm 😕
*L* The only 'attachment' to a physical thing I have is to my saws...my 'axes', if you will. Norsaws....they don't import them anymore. Not typical, but they suit what I do perfectly.
I own 2. I'm probably one of the few people in North America that does. Pity. But only on everyone else. 😉

However, stepping on your speaker is not covered by the warranty....*G*
Might be a fun 'party trick'. I used to demonstrate to people that an Technics SL-10 would play just as well upside down or sideways...and if you gave it a 'twist', it would 'wow' without complaint...
The other was opening a wine bottle without a corkscrew. All you need is a towel and a sturdy door frame. Not recommended with red wine (sediment...). Everyone thinks you've lost your mind, until it's open. Then they just want a drink....

No, I don't indulge in 'that' in a garage. Or my shop. Open horizontal spaces are typically too high to be, ah, 'convenient'....
...and I don't have that sort of 'physical flexibility' anymore...and we all have our preferences, anyway. *L*

Nah, just the typical carbide ones. It's How it works.
Google it.
Anyone that sees them in person is usually impressed. Yes, they're 'pricey', but worth it.
I've owned one for over 30 years now. It's never broken, or needed anything other than cleaning.
The other is the same age, but I've only owned it for about a year now. It took me a year of search 'bots to find one. And was/is worth the trouble and wait....

BOT (back on topic), I took a speaker that I bought for $0.99 from PE, snipped it with my straights, punched a few holes in some AL tubing, added somes bolts/nuts...well, the cone took some practice and a little trig...BUT, it seriously sounds great, I've been listening for hours now.
Lincoln Walsh said in his patent that the design [would take out the empirical aspect of design] and he was right.

C'mon, you don't have to work for JPL to figure this. Where you have maximum physical resistance your not going to have maximum amplitude. Some other parameter might increase, but it's NOT going to be amplitude.

At a college dorm, I had made a walsh speaker out of 3mil AL using a polyethylene coffee can lid as a surround 😀. My roommate literally begged me to leave it behind when I moved. 🙂
3 mil alum....hmmm....sounds like a Bud can to me. *G* Now, that was one cheap-aze speaker. Maybe we've got this all wrong. Instead of considering exotic materials, just make them out of the stuff from the recycle bin....
Foster's cans are nice and big....pity I don't like the contents. *L* And canned coffee tastes like floor sweepings...
Ah, the sacrifices one might be compelled to make to advance the technology. *mock sigh*
BOT...Re resistance vs. amplitude: Now, that's a line also worth looking at. C, your 8 yr. old 'fleur vase' has essentially zero resistance. Now, your new pair has surrounds, which I suspect has some resistance from them. Even if they're foam, there's some.
Subjectively, which plays louder to you? Ignoring any response anomalies, which potentially could be 'designed out' via EnAbL or some other treatment.
There is the size difference, which I suspect will effect the outcome; larger radiating area on the former for sure vs. the newbies. The 3.5 woof individually certainly plays louder than any single one of my array group, but it also has a larger vc/magnet/iron, plus it's surround.
Just a thought...try it with the same music sample of course. The 'playing field' isn't all that level, but it'd be interesting if you've got the same situation happening.
Some pleasant 'homework'. Class dismissed. *L*
(Has anyone other than me noticed that the opening drum solo on V. Halen's "Hot For Teacher" sounds like the idle of a AA fuel dragster? A great way to remove the dust bunnies...)

I think your seeing my line of thought I was on at that time. In short, I was pursuing alternate pathways. But at the same time making a good sounding cone that could be practically fabricated. I know for a DIY'er that is a wide playing field. 🙂
The factor was mainly surface area w/respect to SPL. The surround becomes needed to control the perimeter of the cone base at high drive levels.
The carbon cone was durable, until I dropped it one day and it shattered like a glass vase.
