You, my friend, are a braver man than I. I've got a Cambridge Soundworks Subwoofer 1 (12 inch, 140 Watt), and I think it's a good sub. I've just generally not been brave enough to say anything about it.

That said, I'll probably replace it someday with a VTF-2.

With price as a factor, I'd go with the Adire or the STF-1, simply based on the comments on this board.

I am the Doctor, and THIS... is my SPOON!
