Sounds fair. I was worried that the subs would have no back pressure, and thus move pretty freely. But I guess you guys have cleared that up for me

If they are the new Q18's then no chance.
Well, I don't even own the subs in question, so they would be the "new ones". I have decided from this thread that IB is going to be my best option.

Is the HPF defeatable? I'm not sure why you'd want one at all. If it's not defeatable and can't be set lower than 20Hz, I'd find a different amplifier. There's way too much content down there to just be chopped off. In my opinion, that's unacceptable on a system of the level you're talking about.
Have you read the FAQ over at the cult linked by LTD02 above?
Ooh, okay. So, I would want lost of sound insulation in the room some how, right? To dampen echoes and stuff.
The amp is a Behringer NU3000DSP. I have not seen a way to disable the high pass, but I thought I heard somewhere that I can.
