For those of you looking for a really good home theater or musical sub, this is an excellent choice. They currently have a pre-order deal which is $100 off the official price + 1/2price shipping + Hsu t-shirt. This offer ends today at 9pm Est.
This is the latest VTF-3HO model, which they had at CES..although I haven't personally heard it, I've only heard good things from those who have.
