12" & 15" Earthquake Sub. Build for bbeljefe

[Purplehaze]

So here is a build I recently finished for a member (and friend) bbeljefe, the first of two old school Earthquake subs. This one is a 15" Earthquake Magma 4.0, that he has had for a while. He sent them to me ready to build, so I don't have many pics of them being "refurbished", but I do have a few. I will say they arrived to my house in brand new condition.
The plan was to build it into a beast, able to take much more power than originally. So here we go.

This is what it looked like brand new, years ago.



Here they both are years later



The landing and gap,



"Ass shot w no panties" - bbeljefe


And after a ton of hard work (by him NOT ME)



So then he packed them up and sent them to me, to be "re-born"
I decided to start w/ the 15.

So here I am at first, test fitting everything



He wanted to upgrade the terminals, I can see why..



Using a 15" AR cone, with a standard half-roll foam surround. AR = Aluminum Reinforced (it has aluminum inside, see?)



Then it's time to fit everything up. It all starts with the coil



It is a flat wound D1.4 ohm 4 layer. Much better than the original..





So then the 3 DC med. stiff progressive roll spiders, and 1/4" spider spacer



Then the top half



Fits like a glove. Time to put it all together for good!

More ahead... next post

First thing is the leads. He wanted beefy sewn leads, so I tripled him up on the 1.055 leads. They will NOT be a fail point!



I freakin hate sewing...





So then it was time to join the spiders to the coil, and join the leads, as well as the spacer

Bottom glue joint



Little bit of rubber glue, for the stitching



The spacer ring



Now time to get the frame ready for glue



The whole assembly, after shimming the coil and setting the top. A ready cone assembly



And here she is getting "permanently set"







Notice the terminal upgrade



Coils reading perfect (cheap DMM)



And that's all I got for now. I need to take more pics of the top now, so I'll post that soon.

Anyway, what do you think? (especially Brandon)

Thanks guys.

Maybe bbeljefe will post up a vid or two when he gets it?

Oh hell yeah I'll post up a video. Imma stick it in my old t-line and try to break it. In, that is. ;-)

And the 12 already has a home down in Orlando. I'm building a box for it to go in my nephew's SUV. He'll be going from a Fosgate R-500.1 on a couple of Wal-Mart Pioneer tens in a prefabbed sealed box to a CT Sounds 1400.1 and that sub in a ¼ wave t-line.

He asked if I thought it would hit very much harder than his current setup.... I said we'll see.

Great work Trent. Thanks man!

Dude your nephew is gonna be so freakin happy! This 12 is gonna be a monster!

He will literally be doubling, if not more, his SPL output. And with better sq...

[Keith77]

Bad ass bro... keep the builds coming.

[bbeljefe]

At least... ~4 times the power, about 13% more piston area and who knows how much more xmax... at fucking least a doubling in sound pressure. :-)

looks a little plain ever thought about going crazy with a neon paint job or something?

I hope an invert mount is in that things future.
