That's fine if you are prepared to add EQ and run out of umph really quick.

Consider a normal sized cabinet and adding a woofer designed to do what you want. The 604's I know aren't designed for that.

Thanks for your concern, Cal, maybe I should have specified my needs a bit better, I am not looking for surround-type tear down the walls pumpin' 16 Hz bass, it is more a question of allowing the 604's to breathe freely; I have heard these in standard 7' and 9' boxes and I am quite convinced that they can sound even better, hence my request. And it was that post 604man is referring to, thank you!
