Would this reduce thermal heat in speakers

[vehementSPL 10+ year member]

This is only theory right now. I know amperage creates heat but wasn't sure if wattage could or not ( I know if the amperage is high it will) but is amperage the ONLY factor with creating heat in coils.. I mean if you had 1000 watts and had it wired at 1000 ohm ( I know I know.... example only) it would be 1000 volts and 1 amp. so would it heat the coils up like 1000 watts still or the amperage is the only factor

Heat is expressed in watts. That answers your question. Whether you're talking a 1000A @ 1V or 1A @ 1000v the result is still 1kW that is transferred.

Only things effective in controlling thermal breakdown of driver soft part materials are enviromental - in one way or another. Weather it be increased cooling via air pumping methodology, or cooling via liquid heat transfer. Changing electrical characteristics wont yeild consistant or acceptable output in any situation.

I guess you are not seeking watts, you are seeking db. So, from that side more efficient speaker/enclosure will produce same sound output with less heat.

When you hear engineers talk about current causing excess heat, they're usually talking in reference to a fixed voltage source so the extra current means extra power (watts) which means more heat. At least that's what the engineers around me mean.

word.

you could plumb in some AC into a 2nd chamber in the box to keep it cold. //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

Bags of dry ice have been used to keep motors cool, temperature control is a big deal if you've got the setup dialed in that precisely //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I saw a build last year of someone who took the rear AC unit in a van and plumbed it to like 4 15" driver motors. Id of probably done the same since the AC unit is sorta "extra" back there doing nothing after you build a wall.

Yea but you would have to worry about sealing off the motors from the enclosure as the AC lines would allow pressure to escape.

I just like this thread because it says "thermal heat" in the title //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Ha ha jacob bite it I was tired. Ok Im a computer. Yea same voltage. But does wattage itself cause more heat or does current only. I know typically it is a fixed voltage source so when wattage goes up so does current but what about in this situation. I wanna know if wattage had hardly ANY current would it still cause heat

//content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif that beats the "thermal heat" reference

uhh im not an expert or anything but im pretty sure current=watts....meaning their basically the same thing.

P = I^2 x R

Watts is directly relational to current, not equal to.

Actually P=V*I

In the above equation you substituted the V definition from the other part of Ohm's law. Power is volts times current.

Read the second post in this thread, I answered your question. Watts is heat. Think about it this way, you have a D2 sub. It can handle 1000w thermally. Does it matter on power handling if you wire the coils in series for a 4 ohm load or in parallel for a 1 ohm load? No. Power is watts is heat. Doesn't matter if current is higher than volts or the other way around.
