that thing looks sweeeeeeeet.

Forgot to bring the pics over here from the Facebook :

Attached to 15" frame.

If we do make it the shorting rings (three of them) will be aluminum.

that looks KILLER!!!

We are working out the coil details still -- making it longer than the original is going to be challenging for a D1 coil

any update to this?

looks preeeety tall.

Jake, I think you should send me this sub in a 18in and a NS-1 to test.

I'll pay shipping.

Looking forward to these!!

The D2 coils are in !

12-layers of fury

holy crap

Is it just the photo composition or is that coil REALLY thick!?

Is the driver designed to compliment the NS-1?

That is great!!! I think they will need about 2 NS-1 to power this bad boy, and maybe 4 to get it to a full power potential!!! I might be over exaggerating, but these things aren't designated as "monsters" for nothing!!

It really is that thick.

D2 is together... specs are closing in on where I want to be -- based on what I got from this D2 I think the D1 coil should be correct out of the gate and that the D2 will be good with a tad bit of tweaking :

D2 Revision 1 Coil Specs with 5-layer Z v.3 spider (Z v.3 uses 4 layers) :

RE : 2.93 ohms (series)

FS: 36.87 Hz

QES: 0.329

QMS: 4.326

QTS: 0.306

LE: 6.53 mH (still a bit high but we'll work on the shorting rings on another prototype to get this down)

VAS: 43.24 L

BL: 28.128 NA

MMS: 383 g

CMS: 48.56 uM/N

SENS: 89.93 dB 1w/1m

BL^2/RE: 270 (goal is 300 or so for this driver... revised coil should do it)

I'll do some beating on it soon... have tons of SA-8s to ship... took a short break to pull specs and post them.

That looks loud as balls!!!

My God, how do you work in that room with all that paneling? That shit drives me nuts.

That's off the wall. You are going to do some damage with that thing.

Is there any idea of pre-orders pricing on the 18"?

that thing is loud just sitting there, PUT IT ON SOME POWA!

edit: forgot to mention, when i saw the thickness of that coil, my jaw literally dropped, shit is insane.

was expected coninuous load on these things mentioned ...

what will these coils take ?

Whats going on with this?

I am working on baskets before bringing out a motor this heavy.

Looks very nice. Beast.

Is everyone ready for some news about this prototype ?

YES!!!
