My order #999 was a Q18 Dual 2.  Dual 2 is important, because I'm only running 1 woofer and I need to be at a 1 ohm final load.  I received my speaker in the mail a little under a week ago, and brought it out lat night to do some wiring.  I hooked up the multimeter to the terminals, and...what in the world?  Both voice coils read 5.2 ohms.  Dual 4 isn't even an option on the website?  How did I end up with what appears to be just that?  I sent Shawn an email through the sales email, hoping to hear back today.  I'm at a 3.2 final load, which is no bueno.  I've got 1500 watts on tap at 1 ohm, and I'd like to use them all.
