I have no idea why I said my sub was in a ported box. It's in a very small sealed box. So the subsonic filter is in the right spot.

I think I was typing while thinking about your previous post. So no, it's not ported. That kind of made my first line in the quote sound pretty arrogant. Sorry about that.

But still, why would you not want to filter the frequencies less than 15 Hz when my sub is only rated to 18Hz, though in a sealed (I typed ported again) box? From what I've read, that is a waste of power.
