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.
