The frame renderings themselves are not ready to be shared yet but the cone body and surrounds are ready.

Each surround has the following calculated geometric capacity :

10 -- 50mm one-way (frame allows 45)
12 -- 55mm one-way (frame allows 50)
15 -- 60mm one-way (frame allows 55)

Therefore; each one has a 5mm cushion beyond what the frame can handle in it so the surround CANNOT reach the maximum geometric limit -- as this can cause stress and eventually tear the surround. We've taken note that no open tool / readily available surround can handle what some of our newer designs can dish out already... and future designs will be even more extreme on throw so these surrounds are made to handle anything we can dish out with the new frames.

The foam material itself is also quite thick so it remains stable at such a massive size. Yes these surrounds are insanely large... but we do plan to use them to their full potential as time goes on so they are completely necessary and not just for looks. I am not aware of any surround other than the Earthquake HoleeS that has similar capacity (it's about the size of the surround on our 10" cone).

Each cone fits the same dust cap as the Z v.3 15/18 and the SA-15 -- it is a "****" cap as that design is stronger than the flatter dust caps we have used for years on the NS / older Z model subs. Also simplifies how many different dust cap we have to keep on hand.

The cone body is also quite thick and will be very similar to the material of the Z v.3 18" cones now -- but we may vary the exact material distribution slightly to get a bit more stiffness from these.

These will be used on the X Line, Z v.3 Line, and NS line woofers. We will eventually make 4" coil versions as well for future designs using the same surround just a different cone body.

those surrounds on the earthquakes are huge. I cant imagine what these will look like

They are doing the "offical" drafts to meet the documentation requirements of the patents based on the drawings I already have of the frames -- then they'll get them filed as soon as possible after that. Once I have confirmation of filing from my patent attorny I'll be ready to share :)

since you said your planning 4" coil cones im assuming that the new baskets will but built to take a 4" coil?

They can handle a 4" coil, yes.

will you be selling any baskets or surrounds once you get them in?

ive got a franken woofer in mind and i would love to have a basket with that kind of capability.

I hope the new frames don't require any odd size proprietary parts, best thing about current sundown softparts is people can buy a Z or Nightshade recone and have a quick drop-in upgrade for a lot of other stuff on the market that they need to recone.

Anyway, I look forward to the challenge trying to break some of the new cones :up2somet:

The frames will bolt to a standard pattern -- but the surround landings and cut-outs are not standardized due to the thickness of the frames. The 10" is the farthest off and I know that standard cones will not attach.

Standard surrounds may still fit the 12s and 15s but I haven't really checked yet since we'll be using ONLY our new surround toolings on these frames.

The 10/12/15 frames will all hold a standard 8" spider as well as they all have multiple landings.

I have the go-ahead to show the frame renderings by my patent attorney as I've been assigned a patent application number... we will enforce the patents to the fullest extent of the law as well. In any event here we go :

http://www.sundownaudio.com/misc/protos/New_Frames_2012/Three_Frames_SML.jpg (http://www.sundownaudio.com/misc/protos/New_Frames_2012/Three_Frames_Large.jpg)

Click to see a larger view.

A few people may have been expecting some crazy weird cosmetics -- but this is Sundown Audio where performance is first. The functional layout of the landings, clearances, bolt pattern, mounting lip, terminal location, etc were developed first then the legs and base were designed with the strength required to hold the motor weights we plan to utilize (and then some). Cosmetics fell in place based on the function required -- just like the SA-8 v.2 frame (also patent pending for reference).

So what we have here are the strongest frames I know of, period (about 3x the material of a 12-spoke frame)... with the highest clearances I am aware of on a one-piece frame as well. Not to mention wide enough spider landings to take advantage of it.

This was a Facebook exclusive from Sunday until now so to answer a question that was already asked -- no, there is no spider plateau venting. We will utilize a vent spacer like the SA-8 v.2, the SA-10/12/15, and the Z v.3 18 do now. These spacers work much better with my air-flow designs than a wide open design (yes, I did test that here at my shop with my own test methods).

Also... these will be used on lines BIGGER than the SA line. They are simply too costly to use on the SA line. So the upcoming X line, the Z line, and the NS line.

An 18" version is in the works but will be handled separately next year. Until then I have a bigger spider adapter ring I am tooling for the 6-spoke 18" frame (same size as my tooled 15" basket) as well as a beefier surround to support it.

Nice, deep-dish 6 spoke. I approve of this thread.

Very nice looking even though cosmetics werent really a main point of concern. Should make those big beefy motored subs look even more beefy! :)

To me the functionality makes them beautiful -- but I am a speaker nerd :)

I do not have the ETA 100% nailed down yet as the tooling all has to be made, tested, approved, etc, etc but we should start seeing these in action before the end of the year!

DAng that'll take a long time to break in lol, the surround is gunna look S*e*X*y

Luckily they break speakers in during their QC testing.

Going to have to start saving for a pre-sale. I haven't seen anything on the X line, what kind of power ratings will they have?

I think these are their "1000w" speakers... Not that the ratings really mean anything, they're a step up from the SA series.

Actually a bit of truth to that -- we QC check each speaker up to full x-max so they get some initial break-in

I expect the frame molds to be completed around the 15th -- so hopefully samples of the real thing by months end :)

wth happen to the ns v3?? been a while oh man if that thing came in a 4" coil id be allll over that

The NS v.3 will be launching along with actual production quantities of the new frames -- we decided to hold off a bit and wait for those frames.

The NS v.3 will use a large 3" coil -- we will be working on a set of 4" coil soft parts for the new frames once they are in stock, though, so only a matter of time :)

Im just playing around with it right now and probably over the winter but I would like to do 2-12s next year.
