"You wouldn't think aluminum
speaker cones could fail, but sometimes when kids
hit it with 2,000 watts of a real hard bass shot it'll
just shatter the cone."

The Challenge
Founded by Robert True in 1998, True Technologies is an audio engineering
consulting firm. In 2001 a company called Alumapro sought True Technologies'
advice on a new 12" woofer. Though the field returns for this particular
woofer weren't excessive, Alumapro wanted to make its aluminum cone
even better. Alumapro hoped to "bomb-proof" the woofer to
minimize its failure rate.
The Solution
Using COSMOS to play "what if," True tested some ideas that
led to a completely different design. COSMOS showed that the new design
offered a huge benefit to Alumapro. It reduced the stresses so much
that the redesigned woofer may never fail. "We give it a much better
chance of surviving now than it had before," True says, "and
it was already doing pretty well, so we think we have a winner."
Summary and Metrics:
- Reduced field failures
- Improved product performance
- Accurately predicted real world behavior of the model

"It's
not uncommon for us to run a couple hundred models at a time
and essentially do a noise-free experiment inside the computer."
