Depends on the parts used ; so far these are holding up really well to an NS-1 @ 0.25 nominal on an 18v system for burps (the "traditional" clamp method is showing ~13kw per amp but it's going to be more like 10kw in reality as the double clamp method isn't super accurate). I figure the first thing to go will be the cones before we run into any other issues... then we can move onto the NS v1/v2 style cones which will hold a bit more. After that we'll have to re-enforce cones until I finish my carbon fiber / foam core cones. We have had some of our guys in Russia hit an NS v.2 with 20,000 watts in a small ported box (160 dB no-wall) -- we could use the identical soft parts to that in a Z v.3 motor... it was 5H NS v1/v2 style spiders and the NS style cone with the SPL coil IIRC.

Ton of room to keep going in this thing as well... power is still low, subs are still totally stock models, new sealed chambers, port size testing, internal box smoothing, etc.

Since we showed it out in the wild now here are the pics : * Vehicle is a SEAT Terra * Probably the funniest looking vehicle ever made. * Two NS-1 amps * Closer view. There are 32x D1600 XS Power batteries up top. * Trophies from the weekend; 165.4 in IASCA and 165.8 in dB Drag SS 1-2 * Right now we have two layers of Audio Technix 80-Mil on the roof with a Sundown Logo "head liner" on top of it. * Two completely stock Z v.3 18s in small boxes. We whipped these up quick to do initial testing -- we'll be making better chambers and better attachment methods for them soon. * Through the port... more port testing will be forthcoming as well.

We took it out to a show this weekend and showed a 165.8 dB with it

It's a new vehicle to us -- it's a new test-bed vehicle that will also be entering SPL competitions.

We are working on getting an itemized list from SSA to ship them direct from here; we had a bit too many b-stock so we had to wait for the 2nd truck to fulfill all the orders (we are unloading that one tomorrow)

It's doing alot to revive my excitement level -- and it's a great platform to help me develop our products as well.

From the other night -- left number is dash and right number is kick panel. It's our new SPL project... so far we haven't officially stated what is in it so if you know (shhhhhhhhh) -- but we'll have it at a show soon then, of course, have all the info out there! It's mainly a burp vehicle and the absolute peak is 60 Hz but we have done pretty good numbers in the 40s range as well -- haven't really played lower than that as of yet. We did have it up to a 165.4 as well with a few tweaks.

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

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

I am closing pre-ordering. The amps are due Tuesday to Wednesday.

Just got done unloading the trucks... the 15s and 18s are here in stock for the first time. We have additional 12D2 models for any over-flow overs as well. Any 10s either coil or 12D1 we'll still have to build until the next shipment. Also some X-18 in D2 and D4 were on the truck as well as re-stocking quantities of SA-10/12/15 and SD-2 10/12 woofers.

If you've used 1200-watts before it shouldn't be a problem.

Sure. We don't do it super often but we can. If you ever get on CACO I have "Yard Sales" sometimes with used or b-stock motors.

Yes they will.

It's not super tight -- but it is a little tighter than a Z v.4 series. It is also next to the NS v.3 which has a very open gap for some options we'll have. I figure I'll rated it for ~3500 RMS or so. The stock cones on the TEAM Sundown will be the new SPL cones -- carbon fiber / fiberglass material. The "big surround" cones would be an option.

Cool comparison pictures AND introducing the TEAM Sundown motor that is in development. It will be our first 4" coil motor. Before you ask... ETA and price not yet available. As usual both will be announced when they ARE available. * From Left to Right : TEAM Sundown, NS v.3, NS v.2, Z v.4, NS v.1, Z v.3, Z v.2, and finally the X Motor

The top and back plates are shaped as such to remove the areas of lowest flux saturation to save weight. We followed the contours of flux based on FEA simulation. There really won't be a 'stock' setup to speak of -- I expect most of these to be configured differently. The SPL packs are similar to our old NS v.1/v.2 spiders but bigger in diameter -- we used 3 layers on those models. Depending on the cone / surround they are paired with will determine how many are needed for a certain application. We will also have "pressed packs" like the X and Z v.4 but with 6 layers for the NS v.3

No pre-order is to be offered. 2500 RMS

15" frame in the picture. The NS v.3 motor is a quad stack 250mm design (80mm total slug height vs. 75mm on the Z v.4 -- for a bit of extra clearance)

You know I haven't weighed it... usually weight is the last thing on my mind after making it work right It's heavy for sure, though. I posted specs up somewhere else before -- but Fs is ~40 Hz or so. Should settle down into the high 30s after a while. Linear x-max should be in the ~22mm or so range; with total movement capacity a good bit higher than that.

The X-6.5SW will have a gasket -- but the frame lips are not identical so it may not be a perfect fit.

Here are the photos from Facebook -- I suppose not everyone gets on our FB page so posting them on the forums too : * SPL Spiders shown with the Carbon Fiber Dust cap prototype

It's being driven with an NS-1 @ 2 ohms -- so it's going a bit beyond where it "should" be driven. So yes, at a certain point you'll get a bit of surround dimpling -- it won't hurt the sub, though. The surround is the same geometry as the Z v.3 18" surround.

E is the input from the amplifier.
