Nightshade v.3 Information

[sundownz Pro Seller]

The new NS v.3 woofers will have a HUGE number of options.

1) The motor supports two sleeves to configure it's gap size / overall performance.

• POLE SLEEVES (these are permanent; only selected when built) :

* Copper sleeve – for low inductance / low distortion

* Steel sleeve – for higher BL / higher SPL – STOCK SETUP

• OUTER GAP SLEEVE (these can be swapped when re-coning the driver) :

* 83mm OD – Z v.2 style coils; lowers mass / lowest inductance – for high frequency burps. My next round of Z v.2 coils will have a longer former for use on the new platforms.

* 85.2mm OD – Standard coil; VERY long 4-layer flat coil – maximum linear travel / good mix of SPL and day-to-day performance – STOCK SETUP

* 86.5mm OD – Equal to NS v.2, Z v.3, Z v.4 Gap – we can use any of those coils or any other 8-layer coil desired.

* 92.5mm OD (NO SLEEVE) – I will be carrying a VERY thick coil for maximum BL for this gap… higher inductance and mass so best for low frequency output. I’ll have these in later this year.

2) We will be able to use any spider stiffness level on them… X, Z v.4, or NS v.3 grade stiffness. They are 4, 5, and 6 layers respectively. These are “pack” spiders that come all glued together. We could also vary what diameter spider is used for specialized applications (not common).

* I will also have an “SPL Spider” Pack coming out… we can stack them from 1 to 6 layers thick; each one is harder per layer than the packs.

* The SPL spiders do not have as flat of a stiffness curve as the packs; so they are superior for SPL applications.

* The SPL spiders will come out towards the end of the year.

3) We can also use a Z v.3 style cone on the 12/15/18 models for lower mass if the customer chooses to use one of the shorter coils for SPL. The 10” model will NOT support a v.3 style cone as it's size is not standard. We would combine this with a smaller diameter spider pack to agree with the surround limites. This is a bit of a "budget" SPL cone setup that we can do.

4) I am tooling up a carbon fiber / fiberglass / honeycomb Nomex composite SPL cone (paired with a dust cap of the same material) in 10/12/15/18 sizes. This cone is lighter and stronger than paper – it also features a surround size in between the Z v.3 and v.4 sizing – it is best paired with the new SPL spider packs in their biggest diameter for a given cone size. Due to the reduced cone and surround mass the FS (resonance) of the woofer is increased to perform better for SPL burps. I expect these around the end of the year to early next year if all testing goes well.

-----

With all that being said... I will have to work up some sort of spread-sheet for the pricing on these with options.

-----

Okay so the MAP will be as follows for stock setup units :

10 - $820

12 - $840

15 - $875

18 - $900

Gap OD sleeves will be available for purchase to change the woofer later on down the line. As mentioned the ID sleeves are permanent so a motor will always be "Low Le" or "High BL" once setup that way.

Both sleeves are machined locally in the US and are pretty expensive to make. They do represent a decent chunk of the costs -- but we wanted to have the ultimate flexibility with configuring the NS v.3 so it will continue to be a viable motor for MANY years to come... we could even develop different OD sleeves for it later on down the line

Small update from our machine shop -- we had to go aluminum rather than copper for the low inductance pole sleeve. It was going to run-over the budget by around $100 per driver (ouch!). So that was out. Good news is I have also tested aluminum sleeves and they work very well too //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I can only assume there will be a pre-order price to help us consumers out a little bit

There is no pre-ordering on the NS v.3 line as they are all hand-built

It's a 4" sub...why would you expect it to be cheap? no 4" subs are cheap.

Lol.. He just had to ask

Buuuut. Dat statement about cheap 4" coils isnt true if your buying used. Just gotta wait around for some idiot who bought some then realized he had to pay rent that month and is not selling em brand new for cheap. That's how I got both of my fully loaded SP4 18s to my door for 620 lolol

well fuck my sideways. That was a deal

Yes yes it was, probably would've never sold my sundown nightshade v1 18s if that deal had not came up.

Copied from Facebook update this morning :

 

Nightshade v.3 Update : As many of you know the NS v.3 features an "industry first" gap sleeve system -- the gap sleeves are all being machined locally; our machine shop did move their facility during out order so it has taken a bit of extra time. We do expect the sleeves to be done machining within 2 weeks; then we will be having them coated at another local vendor -- at which point we can start building!

We are making 5 different gap OD sleeves (so 6 options here... as the fattest coil doesn't use an OD sleeve) and 4 different pole sleeves (Gap ID). That makes about 45 possible gap combinations for the NS v.3 motor! Most customers will simply need the "stock" setup so if you aren't super technical don't worry we make it easy by simply offering the "stock" setup that will work great in most setups.

Pulled specs on the first one from the batch we built w/ Red Spiders + XL Leads. Other than the XL lead wire these are bone stock -- just a bit heavier MMS from the extra giant lead wires but otherwise basically a stock spec.

Stock gap spec is 74.5mm steel pole // 85.2mm steel gap OD... coil is ~82.5mm OD and 76.7mm ID leaving a gap of 1.35mm OD and 1.1mm ID.

I also offer a pole sleeve of 75.5mm (0.6mm gap) and an OD sleeve of 84.25mm (0.875mm gap) // basically makes the gap very similar to the Z v.2 model (tightest gap we ever offered) -- for guys looking to burp these; that will pair great with the upcoming SPL cones and spiders for a nasty high frequency setup. BL will shoot up quite a bit with those tight sleeves.
