Investment casting (aka lost wax method) in bronze for the basket. The pattern cost for that would be minimal. Spun copper for the driver. Not over the moon esoterica. Could be done. Wouldn't cost millions. Just a couple of thousand.

I know people who could do it easily.

Cheers

Well. Lets link to the manufacturesite then shall we... :

I don't see anything special. Am I missing something?

Sure. How many would you like to order?

If this driver is ever copied successfully. And if the copy equals or supercedes the original.
Then I'm gonna be very impressed. Very very very impressed man...!

I'd like to see it done. Really. It would be a really expensive unit for sure...!
Maybe even more expensive than the corn fiber 55 pound/15 incher made by Tachyon:

That one cost almost 4000$ per unit. Gotta be the most costly woofer ever?
Tachyon is a bunch of utter loonies! Look at that price!!! It's robbery!

I believe the Ennemoser is even more costly that this one. Not sure of it though.

My dream system has not been built yet. In other words, I'm going to hire a bunch of people to design & build a system which sounds exactly the way I want it to. If that means we have to invent new types of vacuum tubes, speaker drivers, capacitors, or whatever, it will be done.

On a slightly more realistic level, Living Voice OBX-RW speakers, Karna amps, a TVC of some sort, and I'll figure out the rest later.

246, and if you throw in a couple of episodes of Wapner I'll make sure the light stays green...

No really, none as of yet.
I'd really like me a pair of Archaeopteryx'es though! If I could get me a pair someday.

But with all do respect, If you ever wanna copy a good speakerdriver. The 18inch beast by Dieter Ennemoser is the one to go for. My humble opinion!

DGO, if you can make such cones, I'll take 4 for my Lambda's. I could take acurrate measurements.

Daygloworange · « **Reply #29 on:** 18 Feb 2007, 02:13 am »

JoshK,

The basket and cone could be done easily. I'm serious. It wouldn't be cheap for 4 of them, but not 10's of thousands of dollars. The motor's would have to be sourced from somewhere else though. But the basket, machining of the basket to accept the motor and the cone face, could all be done.

I have colleagues that do much more esoteric things than these elements on a weekly basis.

Cheers

Actually I own Lamda 15tdx's, which already have the basket and a killer motor. I'd just like some cones done in aluminum or alloy to replace the paper cones I have on them now. I could send a paper cone in to have it measured to be replicated. If it were big bucks, I'd skip, but for reasonable money, I'd go for it.

JoshK,

If you're really serious, you could send me a hi-rez pic, and I'd have my colleauge have one of his sub contractors that do metal spinning give you a quote. PM me if you're seriously interested.

Cheers

Cool! Good luck dudes! If this coneswap ever happens, do tell what it was like then!

What has not been specifically mentioned here, and I'm not sure if it is realized, is that this driver's cone is made out of wood!

http://www.ennemoser.com/

click on "wood cone" in red, just over 1/2 way down.

Imperial · « **Reply #34 on:** 18 Feb 2007, 11:39 am »

Well, no, that is a different driver.
The woodcone has woodstrips that run into the center/dustcap, starting from the cloth surround.
It bends 3 times towards the center.

The 18 inch Bronze has circular strips forming concentric circles..
It has 4 circles, thus 4 bends before the dustcap...

The Archaeopteryx (1999) was mentioned in the UK 1999, more than 5 years before the advent of the woodcone.
Dave Ayers, Hifi+, writes on the Sound and vision show(Vienna in Austria)that year:
"On show was his 300.000 schilling Archaeopteryx loudspeakers, which are fully C37 compliant. These 100db efficient 2-way cabinets use an 18 inch bass unit crossing over to a heavily modified AMT tweeter at 3kHz (really!). These speakers had the most dynamic drum sound I have heard since I last listened to a pair of Klipschorns. Absolutely frightening! I want to hear more."

The cabinet is made like you would make a violin body I gather by a dude called Kuhnert.
I forgot his first name, Wolfgang? Maybe?

It's a conematerial that is "multilayer-ed" and the C37 lacquer used as a glue evidently. I believe one could call it gopher style? Is that the US word for multilayering a material using only one bondingtype?
The cone of the archaeopteryx is made by copperfoil, really thin copperfoil, or so I was under the impression?
Maybe really thin paper/cardboard. But I think it is copperfoil.
Maybe it now has a woodcone, I'm not sure...
The German word for wood is "holz" and I don't see that used with the bronzecast 18 inch monster.
But I'm not 100% sure of this. Hm, it's possible you are right...

If it is a woodcone. Then somebody please send Kevin at Upscale a mail!
"Yo Kevin, we've got a speaker here, and it sounds like its made of pure woody...think you can DEAL with it?"
