http://cgi.ebay.com/ws/eBayISAPI.dll?ViewI...OX:NEWLIST#LIST I requested that this seller list 100 pieces for me as I buy stuff from them all the time... they put 10 lots up for sale So grab em' while you can. I've used about 20 of em' so far in my truck build

... and yes ... the truck is VERY dirty I'll wash it later *laughs* Pic of the woofers:

Most of the credit so far for the truck goes to Justin Thornton, as I got it from him I've been working on it daily since I got it but the infrastructure of the truck is his work. I will be making changes, tweaking, tuning, upgrading things, etc, etc. I've got a few other woofers I'd like to try in the box, as well as some box tweaks. The truck suited exactly what I wanted to do in the first place so when Justin put it up for sale I jumped on it!

It's really not too bad on music... I need to work on the fronts though... they sound like crap at the moment I'll be taking them fully active shortly, once I can get a crew together to get the cap off so I can change the multi-channel amp setup around and ditch the passives. It does have a mean peak @ 48 Hz... but it still did 152.8 @ 35 Hz

Well, my TL finally came back so put the truck on the meter... my head hurts even with ear plugs AND hearing protective head phones on. First go @ the TL after finding the peak of 48 hz: Legal mic position too: Take a look at my collection of Powermaster D3100s, seven at this time: Used to power four SAZ-3000Ds: Dual Powermaster alternators for the win: While taking that last pic I realized that I forgot to tighten the ground on the top alternator... so I did so and run the truck again: ---- Not too bad! Now... it's time to get tweaking

The drawing for the free 100.2 will be done THIS Saturday! So... if you were putting it off and want these subs, might as well order now so you can get in on the drawing Remember... each sub purchased gives you one entry!

15" Nightshade proto is up for sale. I have a 15" Mag that I am almost done re-coning that will be added soon!

Awesome

http://www.soundsolutionsaudio.com/forum/i...showtopic=10634 The 15" Nightshade has been re-coned with RE parts and is now for sale in the above thread

Nightshade proto has been re-coned finally... added to for sale list. I say the sub is "noisy" -- but it is way quieter in operation than a DD 9500 series Not to scare anyone away, but it's not a sub that I would inverse mount.

Depending on the load the 3000D can exceed 400 amps of draw. In general, on an actual 1 ohm speaker load they will draw ~300 amps or so.

Thats really not bad for a system not set up for SPL

Guess the Orion is going up for sale soon! I just talked to james and I will be going with 2 of the SD1s in a box that should easily hold the v2s whenever they come out. Since I have all the other sundown products I am going to get an amp for the subs as well and I guess it will be the 100.2. Maybe we can use your truck to test the SD-1 v.2 prototypes That would be sweet! What kind of power will the v2s need? Should I get the 100.4 instead and move the other one to sub duty? I don't suggest the 250.2 for sub duty without a fan cooled amp rack. They really won't require much more power than the current SD-1, although they can handle more if you have it. Should sound good on the 100.2 just like the current model does.

I simulated the new X12 v.3 motor design today in an FEA program to analyze my BL and flux behavior. Based on my findings... might just stick with a round wire coil rather than flat wound on this design. Other than that, my graph paper sketch proved to be pretty close. Jacob, If you ever need anything drawn in AutoCAD let me know. Ricky, That would rule... I edited your post a bit so the Feds won't track you down

That is a really loud daily install for sure!

Marcos, If you could send me your full address I can get a shipping quote for you -- [email protected]

Two "B-Stock" SAX-100.4 units added. More random stuff will be coming soon.

Updates have been posted as of today, check original post.

Covered that one earlier Yes, later. No, I don't know when exactly.

D4 will be offered first. If demand is present I'll offer other options later on.

Technically... the v.2 design was pretty good, other than needing a slightly wider gap. That design could have been sold with a gap adjustment and easily was able to handle 600 - 700 watts RMS. I wasn't happy with it's behavior at higher than rated power and x-max... and I had to lay down some QC specifics for the build house (minor stuff). To most people, it would have been considered a good driver except for needing a tiny bit wider gap... but it wasn't good enough for me. Anyhow... v.3 should really do what I have in mind for this design I have much more ability to simulate the design now as well. As for the Nightshade... lets just say I am planning interesting things for it. Final assembly will be in the USA for that one.

Before anyone else asks me... no, this is not the same sub as the following Elevation Audio woofer: http://www.elevationaudio.com/getImage.php?id=104 1) Basket is the same... their back plate has similar dimensions but does not appear to have gap ventilation. I believe their surround is very similar, perhaps the same. This does not make the subs the same by any means. So... we have *two* parts that are the same, and one that looks similar from the side but isn't the same (back plate). 2) Their top plate looks most like my v.1 prototype @ 10mm height. The v.2 had a 12mm top plate. The v.3 is moving to a 20mm top plate. 3) The magnet stack *may* be the same height as v.1 and v.2 prototypes, can't say without measuring, but that is how it looks... v.3 is getting 10mm taller in the magnet department than v.1 and v.2 protos. 4) As an FYI... I changed 5 aspects of the motor from v.1 to v.2 prototypes and the only obviously visible external change was a 2mm increase in top plate height. The v.3 prototype is getting 5 more changes compared to the v.2 design... and will be around 1" deeper than the v.2 prototype... it is essentially a totally different motor, although the back plate will be the same as v.1 and v.2 versions. 5) Their voice coil is different than every version of the X speaker. It is a flat-wind coil... only the v.3 "X" woofer *may* have a flat-wind coil (this is pending), and it will be longer than the Elevation sub based on the specs I can find regarding their woofer. ... and none of us know their gap width, pole extension height, coil layers, degree of pole radius, etc, etc. In short... not even close to the same sub. Shares about as many parts with Elevation as all of the 12-spoke basket subs with a 1/2" tall top plate and "RE Style" half-roll foam surround share with one another. ------ Anyhow... wanted to make that clear before someone decides to post that my speaker is a copy of Elevation Audio and ended up confusing people.

They are all single 8 ohm. Made to pair with a ~400 watt 2-channel amp bridged, something like the SAX-100.2 -- or if you run a bunch of them with a Class-D amp (eg: 8 of them @ 1 ohm on an SAZ-1500D).
