Has anyone used a Critical Mass Sub?

[macalanche]

I just bought a new car that has less room than my Av for a subs. After poking around Google for a while I came across these VERY expensive Critical Mass subs. They're very odd looking but you can build a 1cu-ft box for a 15" sub! I'm thinking about a 10", which I've read will hit HARD with a 1,000W amp.

Has anyone seen or heard one of these things?

I've heard them in competitions, very hard hitting sub if you ask me!
