SAE-800D / 1200D / 50.4 Prototypes
* SAE-800D, SAE-50.4, SAE-1200D * SAE-800D, SAE-50.4, SAE-1200D, SAX-1200D * SAE-1200D * SAE-50.4 * SAE-800D * 800D / 1200D * SAE-50.4 ----- The 800D did well and exceeding ratings but wasn't really THAT much stronger than the 500D -- so I likely will not end up making it. The 500D will be named 600D based on the testing results from it (over 700 after impedance rise). The SAE-1200D did very well, though, and is pretty much on par with the SAX-1200D in terms of power but not quite as small in size. So far what I have pricing worked out is like this : SAE-600D -- $200 MAP SAE-1200D -- $285 MAP SAE-50.4 -- $155 MAP Pricing from an authorized dealer. Testing on the amps so far : SAE-500D: 740 watts @ 2.16 ohms after rise (1.0) 860 watts @ 1.54 ohms after rise (0.5) SAE-800D: 810 watts @ 2.23 ohms after rise (1.0) 990 watts @ 1.60 ohms after rise (0.5) SAE-1200D: 1200 watts @ 2.51 ohms after rise (1.0) 1540 watts @ 1.68 ohms after rise (0.5) No testing on the 50.4 unit yet. --- These are NOT production cases -- just have not tooled ours yet. I do NOT have the ETA yet -- just sharing early data

Sundown SA-8 v.2 Prototype Thermal Testing
The video... super boring but here as a reference to the data.

Sundown SA-8 v.2 Prototype Thermal Testing
I will upload the video soon... will take a while as it's 9+ minutes long but the results really speak for themselves. We compared against a very well respected 2.5" coil driver rated for 600-watts RMS -- many people do run much more than that to this particular driver. The comparison was done simply to give a reference point. I was wondering if it was just me or if I wasn't even tickling this driver thermally with 800+ watts on tap in my car (SAX-200.4 two channels bridged at 2 ohms)... so the question is now answered -- I really wasn't even close to the thermal limits as this 60 Hz test is brutal with very little excursion. On music where the sub is moving 4-5x more the cooling is enhanced by more air movement. So that answered the question about whether my little spacer ring is or is not doing what I wanted it to do :thumbsup: So what this tells me is that I'll probably bump up my official rating to 500 RMS on the SA-8 v.2 -- and that the limit is really purely mechanical on them. I CAN get it to full x-mech on the 200.4 in my car at very low frequencies under box tuning.

Sundown NeoPro 6.5" Prototypes
I am starting production this week... which would put them in last February to early March for arrival.

SA12 bottoming out
It's essentially impossible to "bottom out" the SA-12 -- you can get the suspension to "pop" if you hit the maximum level of throw which is going to be over an inch one-way If it's more of a tick check if your screws are backing out of the box -- an air leak can appear as a tick.

SAZ1500 V.2 issue
We have our 1500s back in stock so if you have pervasive problems we can simply replace it all together.

SAZ1500 V.2 issue
I don't recall the specifics... did your amp go to dB-R or us ? If it didn't go to us at all I'd like to test it out on our bench.

Why does it seem that everyone is against sealed elcosures these days?
I still enjoy sealed -- I typically like very low F3 drivers, though, which either require a good bit of juice or a big box. 95% of my customers do run ported, though, for reference

SA-8 v.2 Prototype Completed
First Klippel graph is in from Red Rock. This sample is offset a bit but thanks to this data we'll make sure they are properly centered on production Suspension turned out quite flat, linear x-max beat FEA prediction, and Le graph is very good as well. I am still tweaking the absolute CMS value as well as coil length to determine the final production spec... but it's very close!

Custom NS v.2 10s
It is a stock NS v.2 coil -- so yes we have it. We sell certain parts but not all of them.
-
Custom NS v.2 10s
The 10" plays perfectly this morning -- and I'm sure the customer will abuse test it well I may end up needing stiffer packs for him but I think this will do nicely based on what Derrick did to a 12" with this pack in his explorer.

SAE-1200D V.2 burnt resistors/capacitor burnt?
I would first take the board totally out and make sure nothing is touching the case -- and from there we can probably help find some parts. I do have a few complete 1200D v.2 boards still as well.
-
Custom NS v.2 10s
I am awaiting our new frames to produce the Monster... not sure on the time frame yet. It is too heavy for a standard frame.
-
Custom NS v.2 10s
* NS v.2 Coil + Triple Joint Ring * Extra large terminals in place * Epoxy on top We'll test it out tomorrow to see if all goes well. I am expecting so but still have a few more ideas if it's still not quite up to what I want from it
-
Custom NS v.2 10s
Spider spacer is in : * The top ledge was designed to hold a bead of epoxy around the spider to keep it secured under high power.

Why are they so cheap!?
Correct. Used 4500s typically go for 850 - 1000 or so on the forums depending on condition. They are still a very good quality amp -- but being used immediately drops a big portion of product value for re-sale; just like the above mentioned car analogy.

Got my PSI Passive Radiator -- What For ?!
I've yet to do an RTA on it... sounds pretty damn good, though. Once I tune it down a bit I'll do a response graph on it.

Got my PSI Passive Radiator -- What For ?!
Some videos up finally :
-
Got my PSI Passive Radiator -- What For ?!
Uploading a few videos... so far on music in the 132-133 dB range on the dash and in the kick panel sealed and window / door open (all about the same) peaking at 40 or so Hz on the song I was using. Will do some more testing tuning the PR down as well in the near future. To me it sounds more like a higher SPL due to how well it handles material down into the 30s and I'm more than happy with it for all of my daily listening. I will definitely recommend these PRs officially for the SA-8s from now on.

Custom NS v.2 10s
I got a first look @ the spider spacer... shop had to make some adjustments but should be able to get cracking on these again tomorrow or Wednesday.

Why "daily" systems should not count on impedance rise
In a car you have high current and low voltage supply -- which in turn makes designing amps around outputting higher current and less voltage much easier / less expensive. In a home you have high voltage and low current -- so amps are designed for that. You CAN reverse the roles in either environment but it makes things more expensive.

Sundown NeoPro 6.5" Prototypes
Okay - I am going to start production next week... and the 6.5" will be in 8 ohm OR 4 ohm configuration (which will eventually show up on 8s and 10s).

Sundown E-10/12/15 PRE-ORDER

Sundown NeoPro 6.5" Prototypes
How much interest is there in these 6.5" ? I am working on getting pricing and details together... if we can pre-sell a good bit of them I may do them sooner than later before Neo gets any crazier.

Sa-8
Correct, they do. You can also get re-built ones : http://www.caraudio.com/forums/subwoofer-classifieds/521553-re-coned-sa8s.html
