very helpful info.

Aluminum might be better because of it's cooling properties (It cools off faster than it does getting warm, if that makes sense).

I am just now looking at: http://www.engineersedge.com/properties_of_metals.htm

where copper outruns alu by large. Pure alu has 220 W/m-C while pure copper has 386 W/m-C. I would believe that higher number conducts better????

Copper has the best conductivity of all metals.Au is less expensive and can weigh less but copper is king.

so copper for every day play.

AMEN Brother !

Actually gold and silver are better than copper, but to expensive to use. Not being a smartass, but it is true.

The absolute BEST voice coils you can get are the flux capacitors, but I believe they were limited to the Funky Pup line of subwoofers. If you can find them though, buy all you can.

I stand corrected. LOL

cool so i will look for a sub with copper voice coils. thanks

one more thing are kapton voice coils and Basv voice coils like some boss subs and poweracoustik sub have are thay the same as aluminum or copper i was just asking because i had a friend that burned 6 per of 15'' boss subs up and thay were under powered and then he tryed poweracoustik subs and burned 4 of those subs up so whats up with that type of voice coil because he now has a per of kicker 15s and thay have aluminum coils and he has had those kicker subs for 4 years and never burned a sub and thay are over powered why is this when thay have the same voice coil as thay say.

the kicker subs may have a better cooling system that the boss or power acoustic. may have better quality coil also.

so if a poweracoustik sub or a boss sub with aluminum voice coils are like a aluminum voice coil in a kicker l7 15 why do the boss and the poweracoustik burn up so fast and the kicker l7 15 keeps on going and thay both have the same voice coils.//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Power handling and cooling abilities also have to do with amount of windings, coil height, wire gauge, motor geometry, and basket cooling design.

I personally prefer flat copper as opposed to round as it gives more surface area for cooling.

why don't more SPL subs have quad V.C;s
when I took apart my 15" Type R.. I just saw one big copper coil... is there really 2 in there, but you just can't see the seperation??

Quad coils arent really useful anymore.

They were outlawed in competition in 2004 and the whole reason behind them was to get more power to the subs.

Back then you could strap 2 1500w amps to each coil for about 12K per sub.

Now you can get 12K from 1 am and have up to 48K per dual coil sub. Problem is that subs cannot handle that power so advancements have to me made in power handling before you can add more power.

This is true.And that is why they use it mostly on small applications such as connections.

Would they also be too soft?

I have always wondered that.
