Figured I'd bring this over here for some of the folks that don't necessarily check our forums as I know plenty of people have been waiting on these.
It will be on it's way to me soon for testing of performance and final specs... also production costs should come in soon so I'll be able to get a cost to customer price shortly.
On to the photos of it all put together !
* Custom tooled gasket to fit our new frame with the Sundown logo embedded. Also a stitched on surround like the newest SA / SD-2 models.
* Side view -- doubled up, tied down, round lead wires to eliminate the potential for tinsel lead failure.
* Also a custom tooled venting ring like the SA-10/12/15 series (complete with logo). You will also note the dual, spaced spider setup. Each spider is 10mm wider than previous SA-8 models for more maximum excursion before mechanical damage.
* New motor design with new magnet boot tooled to fit... this new motor is also complete with a shorting ring on the magnet ID like the new SA-10/12/15 models for lower distortion than ever.
* Rear view. Note the Sundown logo tooled into our new frame.
The new frame tool eliminates the x-mech limits of open tooled frames... it also allows us to use a wider spider and to channel the air like I wanted through the spacer ring.
We were also able to implement dual round leads to eliminate the most common form of abuse damage on the 8s -- which was lead tearing / burning.
So... more ruggedness than ever, and lower distortion than ever thanks to a bigger spider and an internal shorting ring. Testing to come soon on the SPL side... I do expect this to also be louder per watt than prior SA-8s.
Still rated 400 RMS conservatively, box requirements still the same but more forgiving to larger boxes thanks to more mechanical excursion capacity. Many people used larger boxes on single 8s due to the difficulty of fitting a port in the box so we made the driver more capable of withstanding these type enclosures but still being able to work in the same tiny boxes when called upon.
I'm very excited to get these in for testing... I may send one of to Red Rock for Klippel as well to make sure I don't need any more tweaks for production.

Sundownz, I have a question for you
Is the actual cone smaller then the previous model? Maybe it just looks that way.

Good God Jacob! That is a beastly little 8 man!! What's the mounting depth on it? And please do post back in here once you get all the T/S specs for it. I'd be REALLY curious to model this thing up. I have something in mind.

Once I get it in here I'll post up a good bit of measurements both physically and specification-wise.
You know how I roll, though, my first goal is to do 155 dB with four of them in my CRX
Pricing is coming out a bit higher than expected due to the amount of aluminum in the frame, the large internal aluminum shorting ring, extra steel in the motor, added labor to assemble, and the doubled leads -- but I didn't want to make any compromises so it is what it is!
I wanted to keep it around ~150 MAP but it looks like it will be $185 MAP (same as an SA-10) -- of course we have to keep in mind there is really nothing else like this on the market to compare to price-wise. I have NOT added a penny to the price to cover what I paid in tooling -- I am pricing ONLY on cost to produce per unit so this is the best price I could possibly offer on this driver. I think when we see one of these standing next to an SA-8 v.1 it will pretty much explain itself visually.
So -- that being said I will likely produce an SD-2 8" to fill in the large price gap from the E8v.2 ($89) to this guy ($185)... so I'll start development on the SD-2 model soon to come in around the pricing level of the SA-8 v.1 as we know it today so we'll have a full spectrum depending on budget.
Yes, I will measure them side to side once it arrives. I have my expected depth on my notes but I want to measure just to make sure I am posting the right information
I have the pre-breakin specs as well -- they need a nice break-in period to get the more settled in specs. The Fs and Qts will drop as usual. Take note especially of how low the Le is now... this will extend the top-end response and reduce inductive distortion significantly from prior models.
These will go through rigorous testing before approval for production. I am hoping we got it right the first time -- but if I am not 100% satisfied I will make more tweaks before doing full production. Stay tuned !
Chad: No, I didn't model them so my statement is to be taken with a grain of salt and two shakes of pepper. Once I get home in a few months, I will model them though. Along with other subs I'm looking at

You can make an EBS alignment if you want to tune low -- I've done so before and I was pretty happy. I will be sure to update with broken-in specs as soon as I can

Thanks.
