Here's a quote about the sub from Dan Wiggins, the CEO of Adire Audio: "Speaker is operational, we had the sub amp hooked up to the big sub on the other end of the room, so we used a 9V battery to swing the driver back and forth. Only moved ~2.5" one way with the 9V, so it wasn't full excursion. But hey, ever seen a driver move 2.5" one way with a 9V battery? Better question, ever seen a driver move 2.5" one way? posted_image " (BTW that's over 62mm one way excursion with a 9 volt battery)

And here are the pics thanks to Kyle Richardson:

The military had an experimental weapon in the '80's that looked kind of like that. It produced a 4 to 5Hz sound wave with sufficient energy to disable some voluntary muscle control and make the victim fall to the floor...

Actually that isn't cardboard. It is a very stiff, but very light sandwich material. Someone described it on one of the forums, but I can't find it now. It weighs in at 800 grams, which is a lot, but pretty impressive for the size of it. As one person said, it weighs less than Kickers Solo X cone. Of course it would have to be VERY rigid to be able to move so far so fast. After all it's Fs is 7 Hz, and it can do reference output levels as is (no enclosure) at 20 Hz. posted_image

What's really neat is that two of the biggest names in the SQ competition are going to be running these things soon.
