Frozen Subwoofer Testing Results

No one cares about *F except for tards that still dont understand why the Metric system is far superior to standard american units.

Standard american units are bassed off of nothing. "ohh I like this incrament, let's use it"

And the glue that holds the metal part of the processor (resivor?) held fine when chilled to -193 Celcius while the PC was overclocking to 5gHz.

Freezing temperature means the temperature at which uncured CA glue becomes solid...not the temperature at which cured CA glue becomes...ehhh Solid?

It was holding fine to -25 Celcius. If course Liquid nitrogen is more than the difference between ice and boil water...

Subwoofers are quieter when its colder outside

/thread

who cares if cold air would "damage" a subwoofer? its quieter, thats it, it dosent damage anything

Ignorance is often masked with overconfidence.

CBFryman2 : Would that be you soaking a spider and surround in liquid nitrogen then flexing both? Didn't look like it hurt them at all in the pic.

Doesnt look like liquid nitrogen to me. Looks like he used the chemicals in the can of compressed air to try and get the same effects. I doubt it would be the same with liquid nitrogen.

Whats in the glass jar? Water?

we already knew that cold weather would not damage a sub correct? the problem was that subwoofers are often quieter when its colder due to the suspension becoming stiffer in more frigid temperatures, we never worried about the woofer failing, more so it not being as loud

:bows to more knowledgeable then thou:

...dont see why you feel the need to base your ideals off of the metric temperature system...we don't use it in the states...and it doesnt get much colder then 8-10 degrees in the vast majority of the population in the country lives.

However, it's **** cold in florida in those artic winters...gotta worry about breaking your woofers don't ya?

I may be wrong on this...but I usually see a gain with colder tempatures. Now, depending on how cold its output drops I dont know.

Colder the coil the lower the impedance. Lower the impedance the more power. Most of the time, more power = louder.

Where is the test to prove this?

Just to bring it up - cold air is denser than hot air, making it easier for sound to carry, an added bonus.

It sure is cool how someone who is sapposed to be engineering subwoofers decides to make a smart assed remark about my opinion of the american standard system.

I was not only refereing to degrees, but also distance, area, volume, and mass measurements.

On top of that. Celcius makes scence. Among other things, 1 100th of the temperature change between freezing water and boiling water.

The Kilogram and litre make scence. 1 litre of water weighs one kilogram.

The meter makes scence...no only is it divisible by 10's (meaning moving decimals instead of deviding by 12) it is 1/10,000,000 of the distance from the equator to the north pole.

Weight (force) makes sence because it is the force 1 kilogram exerts with earth's gravity.

Joules make scence because it is Newtons over distance in meters

Wattage mage scence because it is one joule per second.

I geuss it just annoys me that a superior system is taught like the bible in science classes, used for track meets and most other forms of racing, but yet we use it on the weather channel and on our interstates. Wattage is used in homes but horepower for engines and motors not in home appliances. The average american is an imbisul compared to the average citizen of a lot of countries that use the metric system yet they prefer a more complicated system of measurments? //content.invisioncic.com/y282845/emoticons/eyebrow.gif.fe2c18d8720fe8c7eaed347b21ea05a5.gif

Metric FTW.

Anyway, that was Dfloroethane... the 'air' in air cans. Boiling point is -24-25* C IIRC. If your car is getting that cold inside over night you probably dont have a stereo in it.

And yes that is water. It's fun to make water freeze instantly. //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

x2

Lower impeadance and more dense air means more power and less energy lost over distance which means louder except in maybe sealed set ups. If it is warmer inside there will be a pressure difference causing a funky suspnesion compliance.

Could be

my original system was in a sealed box, it'd wang in the mid afternoon when i got out of work, but for the morning commute when it was cold as hell, it'd barely vibrate the rearview mirror

if you gonna throw shit at each other... take it out of my thread... //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

always tickles me to send somebody to a thread so that they can learn, and have it fall off into the deep hole of ****ing stupid..
