anyone think 1200would be too nmuch for one?

they're basically like the sa series. cooling is just different

i dont kno if thats true...all it would be is a skar then with a different cone......because thats all the SA was

depends how long it was playing with that power

Uhh...the Skar and SA don't even have the same motor(wider double stack vs narrower triple stack). They're actually a good deal different.

Exactly. Not only is the Skar motor smaller OD than the SA, but the Obsidian has a larger OD than both the SA and the Skar. Differences between the Obsidian and the Skar include: Larger Magnet OD, different magnet ID, taller top plate, wider top plate, completely different t-yoke, different gap dimensions, different cone, different surround, different voice coil windings (height and width), different voice coil former, etc. So no, our Obsidian woofers are not a Skar with a different cone. The Obsidians have a higher BL^2/Re, utilize a lower inductance voice coil, use the same size enclosures, play just as deep, and possess the capability to be louder due to less moving mass than the Skar woofers. And the Obsidian's are $30 less expensive.

Now do those all have the same motor ? Same basket ? How about the coil ? Surround ? Gap ? Motor strength ? Inductance ? Moving mass ? Coil ventilation ?

Each woofer was designed with it's own set of parameters and applications in mind.

One last derail before getting back OT. Here's a direct side shot of the Obsidian and the Skar taken by a rogue ninja:

Hooked my OA15 up in a temp (shitty) box yesterday. 3.2 @ 30hz. And I can tell you that its a NICE woofer for the price. I didnt get to play with it much.. but the few songs I did play, it smashed the lows and sounded great doing it. Also didnt have any trouble getting loud on higher frequencies either. I have a feeling Im going to love this sub when I get a good box built! //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Box looks great btw! //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

looks nice

Another pic just for good measure. SA-12 on bottom, Skar 12 on top.

What the inductance of the Obsidian subs?

What the inductance of the Obsidian subs?

Depends on the coil configuration. You have to consider Re when looking at Le. Every parameter, including inductance, is listed on the web page for the dual 2 Ohm configuration.
