so what you are saying is NEO is the answer..kind a like in the matrix lol!!

NEO ftw!

Got my drawing of the cone I'm planning to use... it's quite unique too -- 15 grams weight and I don't see anything short of 180 dB breaking it *laughs* (this type of cone may end up finding it's way onto some of our other subs later) Surround has linear throw up until 2 mm from the basket running out of clearance... motor is linear up until 5 mm from that point. The spider will be just as linear as the surround.

So the overall design is linear up until right before things start crashing together

OMG Jacob, I can't wait to see what the end result will be like. (assuming everything in the prototype testing works out to your goals) Everyone thinks the SA-8's are badass, these sound like the beat all/end all of the small subwoofer market. Good luck!!

It's about time you released your plans about these

I may have to demo some.

Some cone renderings :

I'm not going to give away what is interesting about the cone -- I'm sure someone will spot it

Nice models. Solidworks? I use Pro-Engineer. Need tool path for CNC? Let me know.

These are actually done in Alibre Design.

i think i spy a flat cone

The face of the cone is flat but that isn't what is so different about the cone

well.. flat cone would = less cone mass.

hmm..

well Jacob you have me lost

SPILL!

Omg, teh cone is white

You do know Yellow adds SPL? XD

I think it's the part behind the cone that makes it strong, the curves.(correct me if i'm wrong.)

... do you see any hollow areas in the cone assembly ?

There aren't any except where the coil goes into the assembly... it's a solid assembly not a traditional "thin" material cone with dust cap.

No, i don't really see it, but i believe in you Grasshopper.

Or maybe i don't really understand you .

How about this... the cone is SOLID -- nearly 2" thick of solid material. It's not just a flat cover on a normal cone assembly.

Solid cone, 2 inch thick and you get 15 grams out of it.

wow , i'm impressed.

(woops i'm spamming this thread a little bit )

Yep! 22 grams with the front cover assembly (metallic looking part on front)-- funny that the cover weighs about 50% of the rest of the assembly *laughs*

OOh, i see a copper ring to lower inductance.. sweeet

The coil is pretty short @ 25mm long due to XBL^2 topology -- which is why "only" a 1000-watt RMS rating.

I am trying to see if I can squeeze a "mini Monster coil" in there... aka: 12-layer flat aluminum. If I can do that I think running a 2500-watt amp on one thermally would be possible... I ran a 4500 @ 0.5 daily on the Monster and for bass-race runs (149.9 from one 15) no issue... and it's coil was only 42mm long.

The "stock" coil is 8-layer round copper... pretty beastly coil for the length.

Oh yah... the 12-layer coil was drawn out and WILL fit this gap... so I will be testing it both ways (8-layer copper vs. 12-layer aluminum).

Very impressive!

I am quite excited about it... if everything works as well as it looks on paper it should be awesome.

I'll test a 12" layer for you

I am very exited. any idea on when a real prototype would be made to test?

What T/S are you shooting for on this driver?

Everyone is starting too come out with neo subs now

It is the future!! smaller! better performance! only down side is it is expensive side of things!

Everyone is starting too come out with neo subs now

For me having a truck and forced to fit subs under my seat, small is best. I can save up if its too expensive. I can't magically make more space. Ill pay the price!!
