Stereo & Electronics - Subthump single 12"?

Is anyone running a subthump box with a single 12"? I have yet to see one and was wondering if there's any out there??

I have a 10" subthump enclosure with a boston acoustic g3 in it. Sounds like 2 12"s in my trunk. If your set on going with a 12" you'll be more then happy but I think you'd be better off with going with one nice 10" setup or even 2 10" subs. The 10" subs are just so responsive and I listen to alot of different types of music. Sub thumps boxes are sick They look stock and it still leave room for the t-tops that's what sold me.

I have a sweet sub that's very responsive. That's the reason for wanting to use it. Hertz ML3000
