sealed box filled with a gas?

[twisztdauthorit 10+ year member]

What would happen if you had a sealed box but instead of just air, you could fill it with a different type of gas such as nitrogen, helium, hydrogen etc... Hoping none of them explode... would this effect the quality of the sound?

didn't see that coming //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

try it out and lemme know

depends on which gas it is and how dense it is.

logically speaking, if it was more dense gas, the effect would be that of the sub being in a smaller box.

and a lesser then air dense gas would be like the sub being in to big of a box

am i right?

I LOL'ed big time when I saw that!

But really, I don't think that anything would happen, and unless you had that box retarded sealed. (which I don't even think its fully possible) anything you add would just leak out.

Applying positive pressure to the rear of the speaker cone could result in the coming of Jesus. Or even destruction of the speaker.

No point. Nothing to gain. You're getting the same volumetric change and thus the same pressure change regardless of the atomic makeup of the gas. Density doesn't matter either. The speed of sound does and that is dependant on temperature not density.

if one was to fill a box with another gas besides air

it would have to be an INERT gas...filling a box with

Hydrogen I would recommend kissing your *** good by

first..and everyone with in a 500 foot radius

Nitrogen would be the safest to use but it would be pointless

there would be no audiable difference

I know when I fart in the car with the windows up theres no change in the noise coming from outside the car.

Air is like 80% nitrogen as it is.

Denser gases will act more like a spring rather than less dense gases. Therefore the sub will more easily reach mechanical limits from its high excursion abilities with low power.

Boyles law says that isn't true.

If the above were true, which it isn't, then this would be exactly wrong. If the more dense gass acted more like a spring, you would get more damping and less excursion.

wasn't this already discussed in another thread a while back??
