the cone and spider, are equal to v1?

Yes, cone and spider are equal to v.1 model -- these parts are very good so I'm not changing them.

I will have double tinsel lead option for the v.2 Nightshade, though

ok..good

are off topic, but I ask Z v.2 in the coil, spiders, and cone, what differ? coil that mounts? I have not seen the photo

Z v.2 uses different coil, cone, and spiders... I'll have photos when they are ready.

ok thanks

will it be 12" , 15" , and 18" baskets?

will it be 12" , 15" , and 18" baskets?

that sounds about right and i remember somethign about a 10 going around.. lol

a 10", that would be wild.

I may consider special orders for 10s.

i found it! said by none other then jacob himself lol!!

on page 2!

Here are some T/S from the 15" D1 that I built for myself with 3 Hard spiders (stock stiffness):

RE: 2.09 ohms (D1 series)

Fs: 32.16 Hz

Qes: 0.48

Qms: 12.04

Qts: 0.46

Le: 2.86 mH

Vas: 47.05 L

BL: 20.07 NA

Cms: 53.44 uM/N

Mms: 457 g

The above with a very short break-in period... Fs will drop a few more Hz when fully broken in. My FEA simulations show 27mm of linear excursion by 70% BL method + it has dual shorting rings to lower inductance related distortion. The at-rest Le is actually roughly equal to the v.1 Nightshade which had a much shorter coil.

That is one bad ass looking subwoofer!

How did you get the Fs so much lower than the V1? That's really impressive because thats right where I like my music. Also, with a higher Vas than the V1 how much more volume will these need?

Just looked @ the site and the specs on the 15" page are wrong... the v.1 Fs is actually around 37 Hz or so.

The 12" model T/S seems to be on all size pages... need to get that fixed.

Talk about a big magnet! Can't wait for an update! I wanna see more!

What's the estimated price on these beasts? and ETA?

That is one STIFF suspension...wow!

The picture on page two makes the V2 coil look round, is it not a flatwound coil?

Will you be doing a presale on these? I want four 12's

It is flat wire -- it is just not a very wide flat wire.

Will you be doing a presale on these?

This.

And at what price?

He already stated they will be around the price of nightshade v.1's but a little more.

Presale is always cheaper, that is from what I have seen here. If there is going to be one, how much $ and when?

Jacob definitely does not tell presale price before hand that will be something you will find out when he starts the pre-sale.

After numerous 10,000 watt burps :

RE: 1.98 ohms (D1 series)

Fs: 31.78 Hz

Qes: 0.448

Qms: 12.20

Qts: 0.432

Le: 2.80 mH

Vas: 50.64 L

BL: 19.59 NA

Cms: 57.52 uM/N

Mms: 435 g

Spider seems quite stable in compliance after a tremendous beating -- of course we knew that from the v.1 Nightshade

insane...10,000 watts...awesome!

I think in the future my geo will have an all Sundown theme that includes two of the 18" NS V.2!

Keep up the good work Jake.

^that would be badass!
