[QUOTE="n2audio, post: 8697389, member: 540940"] Being marketed as IB (infinite baffle -- there's really no such thing as a "free-air" sub) I thought it would have unusual specs, but in Win ISD it models like most low cost subs. It will work sealed or ported. It actually models best in a ported box, but I'm guessing FG on a roof would make porting very difficult. Sealed - 1 vs 2 cf really isn't much difference (.8 to 1.0 even less). There's a slight advantage in the lower freqs with a larger box, but honestly - playing at a volume high enough for it to matter you're going to run out of xmax before you'd ever hear a difference.
