I know that I post some pretty silly questions from time to time...but I couldn't resist this one.

I have no idea what the cost is but I assume this is pretty tough competition for moving air.

The price is ~$7500

I'd hate to be the guy to lift this 350 lb bad boy into the attic, but would love to be the one on the couch listening to it

Why on earth would anyone consider installing this thing in a vehicle? Can exposure to high SPL extreme low frequency waves kill you (make your heart stop)?

Since it's introduction someone on the net "discovers" this driver every month or so.

Can exposure to high SPL extreme low frequency waves kill you (make your heart stop)?

Having been in the room with the Thigpen Rotary sub operating from 10Hz down to 2 Hz at greater than 115dB+, I can tell you that this is more a myth than reality.

And no nobody crapped their pants when the sub hit 8Hz...
