Acoustic treatment

Enough jibber jabber. The reason tiny little bowls work is that the diameter of the bowls and corresponds to an acoustic wavelength AND an electromagnetic wavelength. That’s why Franck Tchang was able to *measure* effects up into the GHz range. In the acoustic domain the tiny bowls “equalize sound pressures” in the room by reducing (absorbing) unwanted high sound pressures like standing waves. We know that’s how they work because the high pressure zones in the room is where the tiny bowls are located ideally. Hel-loo! In the electromagnetic domain the tiny bowls absorb rf. It’s an acoustic resonator. And an electromagnetic resonator. It’s nothing so mysterious and goofy as shear wave velocity.

So you don't know the origins of sound. Tom

Earth to Tom - I know in space no one can hear you scream.

Add your can of hot air to outer space with the shear thats already there then you will have the potential of sound..just like you do here on Earth..Tom

Boy are you out to lunch on this one Tim. It is not what you hear. It is about what you feel. I would bet that you have never played with a system in which you can control phase and arrival times which is why you have this rather flaky opinion. This makes a major difference in the realism of the system. Just wire one sub out of phase and see what you get. I've got news for you. You have to be in phase the entire cross over region. If you are 1/2 wavelength out of time you have one sub wired backwards. This would be the kind of biased unacceptable opinion you swarm guys would come up with. If you think the bass you have now is good, you have a long way to go.
