Well, shoot my reply got deleted (?).

Thanks for the info! "Flat to 20hz" is a good description of what I would like, along with the ability to "keep up" with movie soundtracks. Question then becomes, how to do this? I was thinking that 2 12" subs, sealed, would be ideal but it sounds like maybe not.

I might be able to make 2 15" ported work, but size and weight may be problematic. Is 2 ported 15s essentially the consensus of "ideal" for my setting?

Thanks again!
