Sundown : New 2012 Frames / Parts Thread

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.

Anton Miller did this rending in 3D of the 12" cone and surround :

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 :)

summer is here yet hope you have all this subs done buy then ill sure be getting some!

hook a bro up ;)

Free warranty upgrade? :naughty:

Look like the TI's surround... :inlove:

Hmmmmm I think you need to float a couple of these Corey's way so he can build some stuff with them...

:)

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.

So where do I sign up for stock options?
