So for the poster that said his sub is better than a THX theater (are you serious) Or are you talking about a cheesy theater?
There aren't any THX cinemas in my area, so no, I did not say my sub was better than one in a THX cinema.
I get a lot more impact from my DIY 12" sub in my smaller living room than there is in any of the local theaters.
I would love, some day, to build a monster sub using maybe two
Tumult 18" drivers. Now THAT would be insane.
EDIT: I forgot about the Imax theater up in Seattle. Now that is an amazing theater. The bass, along with the rest of the sound, will blow you out of your seat. Then, of course, there is the amazing screen.
