Stoped by circut city today and saw a huge nitrous tank. Im like with is this doing here. As I look closely i see that it is a woofer and not what I originaly thought it was. Sorry no pics but if I do go back i'll be sure to get some.

 

old news broa, sorry to break it to u. that thing has been around for a long time.

 

Heres the link to bazooka site with those subs, I can't believe they even expanded to different companies like NX and Zex look-a-like tubes.
