Ah, you give the baskets a 'haircut'. *G* I've hesitated doing that, due to the possibility of metal particles going astray. I'm either more motivated by making my own surrounds, but more likely pushed there by using salvaged drivers suffering from surround rot or damaged cones. This does leave me with motors of unknown efficiency, but gives me plenty of 'candidates' for experiment. As with highways and strangers, there's always more than one approach. *L* I've always considered the surround open to investigation, considering the patent's description. And I like using the foamed PVC as a base frame; it's relatively easy to machine, it's pretty inert with regards to any resonance issues, takes paint well if I felt I wanted to 'pretty it up'... If I spring for a new sheet of it, it's available in black or grey as well as white. There are colors, but they're pretty hideous. I like the idea of grey in the long run...
Sanding the stuff is the main drawback. It'll sand, but generates a very fine dust that sticks to Everything, esp. you. Think of a non-absorbent talcum power, and you're there. *Ick* Static, the curse of plastics....
Anyway....😉....here's the first installment of "Audible Abuse", presented for consideration. *evil laughter, trailing off into heavy breathing*

Audible Abuse: Chapter 1a
A pair of AAL model 2000, purchased today @ Habitat for $16.05. AAL was apparently a 'B' line from MTX, made for Best Buy and the rental furniture market. Claims made that they can handle 'lots of power'. We'll see about that...and as for 'Digital Ready'....well, aren't we all....😉

Interesting quote: "I think those are the exact speakers I owned when I lived in a frat house, before I "upgraded" to CV's for cranking. If you throw a keg party out by the fire, crank the hell out of them and then throw them on the fire at the end of the night."
Just my kind of trash. *L* 8" woofers, 3.5" mids, 2.5" tweets, capacitor xovers. Fresh meat....
Woofers have decent sized magnet iron, as well as the typical foam rot. 5mil alum cones, because I still have a lot of it. Tweets and mids, not so much iron; but since they're destined to receive 2mil alum and paper cones respectively (following a suggestion), they might just be able to be interesting on some level....
I passed on a pretty pair of Wharfdale mini-towers...looked like a dome tweet paired with a 6" woofer and (I assume) a matching passive radiator.
But at a $175 ask, I'll let someone else own them. And passives are useless to me....
...and I'm not going to burn the cabs. Particle board is a pain to burn, and it's too hot and humid these days. Dumpster filler after I smash them flat with the Bobcat's forks. I can't tell you how satisfying that can be. *L*

Popping the hoods of the tweets and mids, we find them whole with no rot. Nice, but that won't change their fate. The screens, undented, seem to be aluminum instead of plastic. They'll make nice 'heat sinks' for the magnets if they'll perform their 'new trick' properly...
Magnet structures on both are the same size, interestingly enough. Larger than the V3.5's failed tweets, smaller than the 3.5 mids which are destined to receive paper cones in lieu of the current alums.
Decision: What we'll go for is 4 new tweets; 2 w/2mil alum recycled cones, 2 w/paper cones. Voice coil diameters are 1" on the mids, 3/4" on the tweets, measured at the dust caps. We'll give the 3/4" the paper, the 1" the alum.
The woofs are going to receive alum cones; size under consideration at this point....
Next up: The Surgical Sweet.

Ah, you found some nice "Walsh Ready" speakers. 😀 for a nice price, too.
I agree that making surrounds is doable. Years (and more years) ago I thought about getting a mold made and using silicone. But, nowadays you can get all kinds of materials online.
I'm listening to my little brand-new walsh. I installed a 1.3g paper cone in that frame that I posted. I'll give more info on it after I get some shut-eye. It has good efficiency, and the highs and mids are nice. Just plain-ole light-weight drawing paper off a roll. 🙂
I like simple, and simple sounds good, too. No foam treatment, basically a regular speaker.

IfIf I understood the Argument correctly I don't think you shOuld be seeing any "horizontal" movement at the base. All of that should be taking place at the very top an experiment you could try would be to play sines above 5khz and slide your finger wacross the cone. Same and opposite for below 700 hz

OK, I'll bite. Maximum horizontal displacement would occur at the base due to the change in hoop compliance. Nothing new about that. 😕
Magnasanti, the only issue I'm having right now is; the paper strength could be a little better. Perhaps a paper incorporating some high tensile fibers would work. One would want the cone to track the voice coil radially without much waveform distortion. Right now I'm right at the limit of that. 😉
Ok now its an argument good.. I hope we come to an understanding. I was mainly replying to Jerry when he said "Tangential movement, agreed, is a Good Thing, yes. The amount being expressed at the lower edge is likely being damped by the EVA". I was thinking that was wrong since the "horizontal" or bending or whatever would be focused around the top third of the cone not the bottom now if you played only sines above 5khz lets say for argument the main vibrations should from this argument be focused in the said section. on the other hand lower frequencies like 700 and below should be shifted to the lower half and this would in fact not be horizontal but longitudinal and pistonic in nature. I dont have a walsh driver so maybe you guys could see if I am right?

Honestly they sell chopped fibers both carbon and glass. Maybe if your not conformable making a cone from a sheet maybe you can simply paste the chopped strands like a hi-end adult paper mache project.
yeah perhaps I am not trying to be crass. I honestly dont know but the opposite can you point me to a source? Also at stasis theory would suggest what do are you defining as the bottom?
The tangential wave component is going to manifest as it progresses toward the base due to hoop compliance.
You and I must be reading different things I may not have a good source. But from a logical point the tangential waves would manifest at the stiffest part in that case it would be at the voice coil end not the base which is highly complaint in comparison?
😕Wouldn't a more compliant situation allow for more tangential? Or, are we thinking in opposites?
