Line up 100 of them back to back and see if a bullet can make it through all of them.

It's also a matter of the weave and construction of the Kevlar, though. It would take a hell of a lot of drivers to stop a bullet.

We're forgetting the primary benefit of Kevlar as a driver material. It looks cool and high tech. That's better than bulletproof to the marketing departments.

My M-Audio BX8a speakers have a kevlar driver. Looks cool and carbon fiber weavey. I wonder if M-Audio would be able to sell a similar speaker that used a treated paper cone instead of the kevlar. I doubt it, even if the paper cone version sounds better. It wouldn't sell sitting in the showrooms next to the KRK monitors with their yellow aramid composite weave drivers.

I would try wiring a voice coil/magnet to a Kevlar vest and see how it sounds.

The glass in a bank teller window is bullet proof, a plate glass window in my house is not. The same holds true for kevlar, it is a strong material, but it does not have supernatural properties. Same materials, different applications.

bullet proof vests consist of over 50 layers of kevlar. not sure if the same applies to my KRK RP6..
