What I'm wondering is at what point is a sealed box large enough to allow the drivers to have the extension they would in a ported or IB design. I have the space, if I can get away with not having to port the box I would feel much more confident about building it.
This is 4 RL-p18" in a 900l box w/ 2000w. The rolloff difference between a 1000l box and a 10,000l box is fairly small. Much flatter than the ported design I was looking at. It shows a Qtc of .74, is this ok?
