Dont get hung up on FS off the driver. The parameters allow the Q18 to be modelled fine. In a sealed sub you would need 5-6 cu ft to get a qtc off around 0.7. No disrected to Dan who is a very nice guy loves sealed subs and is not a ported sub lover. I like either and if modelled correctly a ported sub can sound as good as a sealed one. What you have to remember is when you go the sealed route to compete spl wise to a ported you need twice the drivers and twice the power to run them.
I am one for more than you need but that is me. My ported subs are very very clean and having have the luxury of being able to seal them to get a good qtc I always go back to ported. If I had the money for 4 18's I would go sealed because they would sound awesome and have the displacement to get me low and loud. Especially as behringer have release the new 4 x 1500 watts rms pro amp. That would suite the duals perfectly.
