Please e-mail me for shipping quotes... it is clogging the thread.

Before anyone starts a fight... I am just offering a comparison of parts counts, sizes, etc. I am not saying anything bad about the AQ product.

I don't have the prototype yet and it takes 2-3 months once I approve the prototype and start production. So yes, a few months out.

Sent in my design specs to the factory today for an SA-8 driver. Will move down to a 2" coil, though, so we can fit the proper spider on the frame. Coil will be 33% longer than the E8 coil and will feature all of the SA-12 cooling features. Frame will be 12-spoke rather than 4-spoke as it works better in the 8" size. May have pics in a few weeks Motor dimensions are similar to SA-12 except for it is narrower to more easily fit into an 8" woofer cut-out. Power rating 400-500 watts RMS. As for the X8... I may start from scratch on it due to the difficulties of using a 2.5" coil on an 8" driver.

Working on it !

They made it in... pre-orders will start shipping today.

Yes sir We have even improved them for the next production run... not that they needed it, but that is how I roll.

So... you want to know how much the SA-12 will take thermally ? Video starts at 14.5 amps (1740 watts) power drops off to the 1200 - 1400 watt range after the first 10 seconds and continues to play for a total of about 35 seconds at this power level. Never going below DOUBLE rated power for the entire time on straight sine wave wall socket power @ 60 Hz. The woofer is NOT broken but I decided to stop as the current continued to drop indicating the coil was getting too hot. I plan to use this one in my Jeep so I didn't want it to go until it quit http://www.sundownaudio.com/misc/SA-12_Production/Wall-Socket/CIMG2652.MOV Fun stuff This is a Dual-2 -- first sample that I built yesterday -- so nominal load was 4 ohms. I didn't use the Dual-4 (production) since it would be either 8 ohms (not much power) or 2 ohms (too much power).

Part II at 2 ohms this time ! Way too much power but we did it anyway! Played 19 seconds before failure at 400-600% over rated power. Started at 3720 watts and dropped to 2472 right before failure (multiply the current by 120 volts). Don't try this at home.

Here we go... it FINALLY processed on YouTube:

SA-8 will come in Dual-2 at first... four (1 ohm) or two (2 ohms) on an SAZ-1500D or one each on SAX-125.2 @ 4 ohms. Also for SPL heads... burping two at 1/2 ohm on a 1500D. Motor is 6.14" wide and 3.05" tall -- pretty beefy. I am looking at 1000+ on burps and 400-500 daily... we'll see how testing goes.

Either can be extremely loud. Team Nemesis Steve is at 156+ no-wall with a slot port box... many folks didn't think that would happen. I'd like to do a direct comparison one day with the same box design but I have not yet done so apples to apples. It is my theory that for a slot port you can make up for the lack of smooth flow with a bit more area.

I am closing this... I don't see any reason for a fight on the forum about this. If you want help, let us know. If you have already made up your mind - that is your choice, sorry to hear it.

It is a very established fact that the 3000D is a very competent competition amplifier -- any claim to the contrary indicates an issue with the setup / application to me. I can protect a 3000D at 1 ohm nominal with a straight burp and my head unit maxed out completely... I can also roll it at 1/4 ohm and 18v with the same head unit when dialed in properly. Any of us would be happy to help - I don't recall ever hearing from you about the subject. Protection indicates a condition outside of the operating parameters of the amp -- you may need to roll with your particular reactive load (which you did not specify if you were or not).

I do the best I can

Great ! We'll get you fixed up ASAP

Both the SA-10 and SA-15 will come standard with two performance upgrades from the current SA-12 (the next run of 12s will include these standard too). 1) Custom tooled triple joint strengthening ring. The only failures to date under any condition of the SA-12 have been of this joint under *extreme* abuse -- in my case 1200-1800 watt burps in tested. 2) 12 drilled basket holes for cooling rather than four. After extensive testing I found that 12 holes are more beneficial than either 4 holes or a "wide open" setup like the basket spacers on Nightshade 18s and/or the 12-spoke frame. The air velocity stays high but allows more flow than the original four holes. I can add both of these during a re-cone

MSRP ~$199 or so as the SA-12 is $249 MSRP. I will pre-sale them for ~100 shipped more than likely, though!

In car audio there isn't much trusting of anyone to be going on until there are many independent tests of a product. There are no real manufacturer standards... even CEA-2006 doesn't cut it. I have seen products fall short of their CEA rating when tested independently.

$26 shipping. It pretty much does just multiply until you get into really large shipments.

Yes they are D4 -- they come with blank caps as they are not an official Sundown product.

I would just do one amp at one ohm.
