Really great and thorough response, thanks Bruce!

I like the feeling of awe from sub-audible stuff, such as 16Hz. It sounds like the LVX12 can pull off a little of that though, no? Beyond that point, I have no interest in shaking stuff just for the sake of being able to.

It's easy to get lost in wondering, would a sealed 18" aluminum sub be tighter and more musical in audible frequencies? Or maybe the smaller 12" paper cone, with its lower moving mass would be tighter, despite the ported enclosure. It would be awesome to be able to audition a bunch all at once!
