Vids up.. Page 6!!
Why would high end spl subs use alum coils if they weren't as good as copper? When I have competitors telling me that the alum coils can take much more power, and the owner aswell, I would believe it... Everyone I talked to is pretty honest. But to fully understand it, I will email dj from audioque, and maybe he can break it down for us. Every major spl sub uses alum coils... So something is up... I will let you know what he says
I asked dj the onwer of aq/ Dad of onwer of Digital designs about the coils, and this is what he said.
With the aluminum coil HDC's there is more surface area on the coil to
dissipate the heat( the coil has 8 layers of wire, the copper coil has 4
)plus the suspension package on the aluminum coils will handle more
power. It has six spiders laminated together and is hand built in our
shop with our own glue. This suspension package will handle considerably
more power then the copper coil version. The coils and spiders are
American made and hand assembled. The whole sub is optimized for
competition.

For easy math
4 layers of copper = 10 grams
4 layers of Aluminum = 5 grams
So for equal weight
8 layers of Aluminum = 10 grams
Therefore giving you more surface area. In that manner I can see. Why it didn't cross my mind before ?????

Yup, it makes a lot more sense. If they are using twice the material, it is a gain. If memory serves, copper is only about a 30% better conductor than aluminum. I guess I assumed that it was a like for like coil, just different material.

New batt anyone? Will function as my amp battery for the mystery amp coming in next week. These bat caps are very powerful. Coming soon

Well, when I first tried to get this thing, I had just graduated highschool, and was saving to buy a car. Then since they sold out of them, I had no way to get it.

Here is what the box drawings look like.. I will more than likely put the subs on top, but here is how it comes out.. I would like more port area, but the subs needed to get some decent airspace, as 2 18s take up alot of space, and having a trunk car limits youre space aswell.
9.3 cubic ft @ 38hz with 115" of port
Yes the tunning is high, but dd/aq woofers like high tuned boxes. They still smash the lows easy.

Love the surfboard and the Xenon's.
