a sub in each corner

[Movie Man Don]

Both Blu Dog and Big Daddy share very good points. In my case, trying to maintain a "theatre" type environment in my screening room it was impossible to install subs anywhere except behind the screen. As I shared in a older post I found that facing the subs toward each other (about 10 feet apart) produced an extremely satisfactory results. I don't think there is a cookie-cutter answer to sub placement all the time but surely the graphics offered by Big Daddy make a lot of sense. I think in my application using two commercial 18" JBL's with high power amps has over compensated for not having four subs. When those suckers kick in you don't have any idea where it's coming from and certainly there is no lack of "effects".....trust me.
