We're green...yea right...recycling is done to save MONEY. But yeah..pretty amazing

[derbigpr]

What's so amazing about a design that takes about 15 minutes to do in any simple software such as Autodesk Inventor and then use a CNC machine to make it?  This guy would have a heart attack if you show him the production of something a bit more complex than a paper thin aluminium cone....an engine block lets say.

[BasHorneman]

They are not sparing any expense making the cone. I just had to laugh that they say they RECYCLE because they are concerned about the environment. They RECYCLE because milling a paper thin cone leaves masses of aluminium which they obviously sell back. Hence they do the RECYCLING for the money is what I said.

[BuzzardSalve]

What they have done is good from a performance point of view but wouldn't it be cheaper in the long run to build a cast and make the whole cone by pouring molten aluminium into the cast similar to the way an engine block is made etc ?

[tomislavgasparic]

That operator on winding machine must be deaf from all that noise.

[Oneness]

They are doing the recycling for two reasons, Green and to recoup SOME money back.  Remember, they buy the billet aluminum at a premium price and get paid scrap prices for the aluminum they recycle, so they effectively lose quite a bit in the process, just not as much.  They aren't a high volume production shop, so they are only saving small amounts of money by recycling per speak system.

It's the most clumsy possible way of finding a solution to a problem, and still has many shortcomings. I'm not saying it isn't a good cone, I'm sure it is, but the way of getting there... there are many easier ways of getting there, and by easier I mean cheaper, with a higher quality result, so this becomes an exercise in stupidity.

Your suggestion for an alternative is good but lacking in understanding... why would you use an adhesive?

[paulusandronicus]

To save money? are you freaking kidding me? They are machining a paper thin cone out of a block of aluminium I don't think they are too concerned about saving money. If they wanted to save money they would just make a stamped cone or use a different material.

[nathanaelgreenaway]

Wow, from a science/engineering point of view, this is literally the worst way you could manufacture a speaker.

[cskabos]

What a waste of materials and energy. Metal speakers never sounded good.
Better buy some vintage Alnico or Tannoy paper speakers, they sound amazing.
Unfortunetly quiet expensive they are from $600 to $6000.
