get whichever one will let you wire to the load you want. 2 Dual-4s will wire to a 1, 4, or 16 ohm load. 2 dual-2s will wire to a .5,2, or 8 ohm load. one dual-4 will wire to 8 or 2 ohms. One dual-2 will wire to 1 or 4 ohms.

Kove Audio Armageddon Z-12
Kove Audio was founded fairly recently in 1997, but the company owners have been in the car audio business for over 27 years, having founded at least one other well known company. With an imposing name like "Armageddon," the Z-12 was an all-out project for Kove, with Gary Kovner's instructions to his chief engineer to build the best woofer possible, and never mind the cost (for more about Kove Audio, visit http://www.koveaudio.com).
The Z-12 is built on a cast aluminum frame that has a substantial 40 mm (1-9/16") of reward travel for the spider (this includes a sizeable mounting ring for the spider), painted with a good looking grey wrinkle finish. The motor structure for this woofer features dual stacked 190 mm x 25 mm ceramic Y33 ferrite magnets sandwiched between some very serious metal. The front plate has been milled and polished and finished in a black coating to increase its heat dissipation ability (the black body radiation effect). The back plate is a CNC machined T-yoke (pole piece and back plate are a single piece of metal) that has been milled and polished with the Kove logo engraved on the back, but without the black coating. Magnets and plates are covered by a black rubber magnet "boot." Like most woofers in this class, the pole piece includes a 10 mm extension to improve the linearity of the forward magnetic fringe field. For cooling, the pole has a 35 mm (1-3/8") diameter vent with radiused edges to prevent turbulence noise and improve air flow. Incidentally, the engineers at Kove use all my favorite tools for design, LEAP, LMS and SpeaD (SpeaD is a fairly new program from Red Rock Acoustics that allows a speaker engineer to input the specifications of all the parts in a woofer and have the program give the T/S parameters).
The cone assembly for the Z-12 is also impressive. Subwoofers that handle this much power need very stiff cones, and the Z-12 achieves this with a thick-coated fibrous pulp (paper) cone with a integrated Kevlar mix. Finishing off the cone is a 4.75" diameter, heat-formed 3-D concave shaped dustcap. Connecting the cone to the frame, Kove used a dual density heat pressed foam surround that measures about 35 mm wide and 21 mm high. Kove uses a black Santoprene mounting gasket that covers both the front and rear of the frame mounting area.
Remaining compliance is provided by a pair of black 7.125" diameter poly-cotton blend progressive spiders. Kove primarily intended this high powered sub to be used in vented enclosures, hence the progressive spider (the two spiders are mounted in reverse direction back to back). While the woofer will work into a sealed box, and I did include simulation of this woofer in a sealed box just for comparison purposes, its stiff progressive suspension causes a fairly high rolloff. Still, it is capable of producing tremendous SPL. Like the other three woofers in this review, the Kove uses the new type of spider with the tinsel leads woven into the body of the spider. Industry consensus seems to be that this is definitely a superior way to handle the tinsel-to-connector path. The tinsel leads are terminated to a single set of color-coded chrome push terminal designed to accommodate large wire gauges. All parts in the cone assembly are held together with a high temperature "aerospace" epoxy. The shuttle doesn't fly apart and neither will this woofer!
Powering the cone assembly is a 3" diameter voice coil wound with aluminum round wire onto a black anodized aluminum former. Using the aluminum wire cuts the assembly weight giving the woofer greater sensitivity and acceleration. As mentioned in the beginning of the review, this woofer uses a single 4-layer voice coil, so it has a DCR roughly twice that of the other three DVC woofers. When looking at the comparison data chart, keep in mind that the other woofers take less voltage for a given output because both coils are parallel driven in the simulation.

if i wanted the 12" d2 would i get this

I was suppose too. Because i wanted to show everyone what this baby can do. This model Z12, is the top of the line of kove audio. And the people that know there shit, knows about this woofer. I just don't have no use for it anymore. I know for sure this baby will wang out the type arghh..
Mojo would be a better SPL sub, but you're not going to find it in your price range. I say go with a ported Type R. you can get them for about 100 bucks a piece and they handle 1000w all day long
