I have never seen tibetan bells made of fused quartz, just bronze.

I brought the bells up because here is something 10 to 20 times bigger. It may not be 'tuned' to these high frequencies, but it sure as heck resonates more in all frequencies than these little objects. All bells give off lots of high frequencies. In fact many objects resonate all over the place at frequencies above hearing. Glass, metal, even some wood.

There is an acoustic theory about the interaction of soundwaves of different frequencies. Soundwaves of different frequecies can interact in the air, changing both. So a high frequency tone can change the way a lower frequency tone propagates. Or the both tones can change the way a receptor (Mic or ear) hears each. So a very high frequency may change our perception of bass for instance.

This is one theory on why super-tweeters may change the sound of a system. Many people who listen to systems with supertweeters report tighter bass with more definition. I've heard this myself.

I have also heard the FAST products enhance image and soundfield.

I do believe they work to some degree. But I also believe that something from more ordinary materials (brass, bronze, etc.) could certainly be developed that does the same thing. It might be a bit bigger.
