If I am not mistaken, this is the same gas they fill windows with to make them more energy efficient.

Windows are filled with Argon. Not sure how the two compare in density or thermal properties.

Mount the driver firing upward because the density of the SF6 would induce it to settle in the enclosure.
One other issue... at high temps it decomposes into Fluorine which is extremely reactive. You would have to make sure your VC temps where low or somehow isolate the SF6 from the driver.

Kevin, at what temp does this occur?

I'd imagine up around 300-600 deg C. I'd have to research it more as I'm not an expert in SF6 reactions. ;-)
The thing is Fluorine is nothing to mess around with. Its very reactive and poisonous to boot. Its really nasty ****.

yes, you can even model for this in winisd, but the differences aren't as dramatic as what's being discussed here.

Hmm... 300C would be about 572F. If you get a VC up to that point your driver doesn't have a chance to withstand much more. You would essentially need to have a bladder of a soft material that allows for the transfer of energy from air to the SF6 gas. As long as you keep that bladder away from the driver by even a very short distance it should never have those heat issues.
You can look up the patent if you wish to know more on how it was originally done.

Just wondering since we are on the subject of exotic tech to apply to subwoofers..
Would a colder driver or enclosure ambient temperature make any changes to performance?

I saw something on a car forum where they took a component set and subjected it to temperature changes that may be experienced in a car, then took measurements. The woofers TSPs changed for the worst outside the 50-100ºF range. 0º had the Q and fs rediculously high if memory serves me.

When I used to be a 'hardcore' computer freak I made a freezer style case that I loaded with peltiers. I'm thinking it could be possible to do something similar to a subwoofer. I had the hot side on the outside of the case and the cold side on the inside. A 120mm fan on each heatsink, ambient temperature inside the case was something like 20 degrees F.
I'm thinking a module that would blow the cold air into the sub somehow. Just a thought.
