Ryan's right, in your vehicle with the driver(s) in an IB alignment, it's impossible for us to calculate F3, F10, etc without actually owning one and testing it ourselves. Like Ryan said, IB will give you the deepest flattest response possible. It also takes your power handling and chunks it out the window. With the response that the new Mag and BM's are going to have in small sealed boxes it's kind of fruitless to want an IB install.

As it stands now, the new Mag's F3 is 10 Hz lower than the current Mag's F3 when they're both in 1 cubic foot sealed. 10 Hz lower is a BIG difference!
