I once worked at a company that shall remain nameless...they had a cool looking magnet structure, super beefy. 18" woofers. At one point the aluminum baskets were...improving the strength of the basket to minimize structural failures during handling and transportation.
1.8 mm thick!?!?
Yeah, they broke a lot. So I redesigned the basket to be much stronger, and easier to manufacture. But since they had literally containersful of baskets (why so many???) they kept building with the old baskets
