I don't suggest it... will add alot of stress to the amp and significantly shorten it's life span.

Until they get here.

They are rated 600 RMS. You can look around at reviews and make your decision based on that.

If a speaker wire grounded out it would have damaged your amp.

The recones come as raw parts so you can assemble them to fit the E8 v.1 motor with the correct coil height. I have not done so yet as I don't have E8 v.2 parts in stock - so no specs. The v.2 coil is actually a few mm shorter to help prevent bottoming out and destruction of soft parts -- xmax is really close, though, due to the taller top plate. Either coil can handle over 200-watts -- but the soft suspension on the v.1 especially was a limiting factor to 200 watts RMS. As for the spider... it is a little stiffer and also wider. Surround is designed for less throw but is a rubber material so will not tear. You can see the videos I have up... has plenty of throw -- at excessive power I can reach the basket mechanical limits with it but at that point the rubber is actually stretching a bit. The v.1 surround was too much surround for a small driver so I scaled the roll down alot. The v.2 motor is stronger than the v.1 as it is slightly larger (not much). ETA not available just yet.

Couple tenths... not really significant. It does make it alot easier to work in there, though.

Oh yah... rounded all outside edges of the box and around the port mouth this morning -- zero change in SPL.

Been playing with it a bit and still not quite up to Magic Box v.1 performance... need to figure out what works best in this box. Interestingly the 3 Spider Z v.2 was louder than a 3 Spider Nightshade v.1 in this box at equal power (as three NS spiders is a bit less stiff over stroke they are louder in the 15" v.1 enclosure - 2 Z v.2 spiders was roughly equivalent per watt). This leads me to believe I may need to build several 18s to see what configuration is the loudest. Plan to build a 2 spider model and a 4 spider model and run them all to see what happens.

Yah, I think so. When I get more power again.

Results so far with Z v.2 18" D2 with 3 Spiders (too stiff for this box): 420 watts = 144.6 520 watts = 145.5 660 watts = 146.4 830 watts = 147.2 1040 watts = 148.0 1310 watts = 149.0 1620 watts = 149.8 1790 watts = 150.1 1960 watts = 150.4 2340 watts = 151.1 * Let Sub Cool for about 15 minutes * 2530 watts = 151.6 3110 watts = 152.4 3390 watts = 152.7 3530 watts = 152.9 3860 watts = 153.1 4160 watts = 153.4 All results @ 53 Hz / dB Drag on the dash sealed mic position on the TL.

The "secret" is a bit more complicated than the pictures might imply... I'd be impressed if someone figured it all out from the pics I spent all morning the other day reverse engineering the old box since we built it 3+ years ago *laughs* Then I scaled it up and kept the important ratios identical to the old box but a bit larger for an 18.

Took some pics of the process -- thanks to Brandon for helping me get it done in a timely fashion. * Basic shell complete. We are using mostly cabinet grade Oak plywood (3/4") with some 7/8" ply as well (bottom panel and one layer of top baffle). * I like to use lots of screws... 2" long models. * Temporary guide setup to build the port straight * Outline walls of the port... ready for flexible ply. * Flexible ply installed to make the flare. * Coming together ! * Filling in across the flare with strips of wood. * Wood filler in the gaps. * Fiberglass cloth and resin applied. * Top baffles going on. * Hole cut with counter-sink * In the Jeep ! --- I installed the only 18" I had laying around in there and it is a hair behind the old Magic Box per watt so far... but this 18" had an extra hard suspension which is terrible in a box this small. So... based on results so far I expect this box to pull ahead of the old Magic Box once the correct spider configuration is used. It seems to be functionally nearly identically just with more cone and port area (and a bit more volume).

It was designed for more power while remaining nearly as small... the 1000D is a very reliable amp.

I have a prototype large 4 channel I plan to test soon... not sure if / when I would produce it. Is in fact 1 ohm stable... for running large PA speaker setups.

I am toying with a big boy design... but not seriously. I am still working on launching the 4500D to bigger production numbers before I even think about it seriously.

As long as they fit depth wise you can. May get some port noise with the Zs, though.

Waiting on word on the amps -- should be here in the following days.

You should be able to fit the woofer forward to dash and port to back of the trunk if you use smaller diameter port pipe for shorter length. This should result in more SPL. My enclosure is 0.5 cubic feet each woofer -- 14 liters for each (so 28 liters for two).

Yes, like my enclosure : Also, have you tested applied power with meters to check actual amplifier power to the woofers ?

The problem is phasing of port to woofer cone. It would be ideal for SPL for the woofers to face forward and the port backward. Can you fold down the seats for SPL and do this ?

Pre-ordering NOW OPEN... pre-order runs until July 4th or while supplies last. ETA is the end of July -- as always this is subject to delays and is not set in stone! COST : $315 shipped in the continental USA - Regular MAP Pricing is $375 * Contact me for AK and HI orders * USA ONLY SALE IF YOU ORDER BY the end of May it will only be $300 each shipped in the continental 48 states! TO ORDER PAYPAL ME AT [email protected] with Subject "SAX-1200D Pre-Order" or talk to your favorite online or local Sundown Audio dealer. ----- This is an all new board tooling developed just for Sundown Audio. RATINGS: 1200 x 1 @ 1 ohm 720 x 1 @ 2 ohms 360 x 1 @ 4 ohms ** -- Clamp testing coming soon... will post in this thread. These amps CAN be strapped. They are NOT 16v stable like the SAZ line and long term 0.5 ohm testing has not been completed. They have 4 awg power input terminals and 3x 40-Amp fuses. Effective real world power is expected to be significantly higher than the SAZ-1000D! Dimensions : 252(W) x 58(H) x 310(L)mm (9.92" x 2.28" x 12.2") ----- * SAZ-1000D on left / SAX-1200D on right -- dual transformers and output inductors + new more powerful MOSFETs... all N channel outputs vs. N-P in the 1000D. * Side by side with 1000D for size reference. * Close up shot.

yes they can - but he wants to control FOUR amps with one remote.

Debating... so far they have been significantly more reliable than the v.1 model -- if that continues I will keep them around.

I am working on alot of things for the end of 2010 and beginning of 2011... expect lots of new "entry level" stuff.

DONT DO IT. I used to use it... don't bother.
