I am going for a setup with sealed boxes.  I have two sealed boxes that are 2.6 cubic feet per box.  I noticed that everyone is saying to go into the direction of the BL line, but I also did not notice anyone say anything about the type of enclosure that will be used.  FI claims that the BL was not designed for sealed, so I ordered two fully loaded Q15s.  Did I make the right choice or should I have went with the BL instead?  I like sound quality, but I also like it to get loud.  I am upgrading to these FI subs from two Kicker Comp VX subs.  I would assume that either one of these two subs will blow the Kicker sub out of the water, but I am wondering if I went in the right direction on this one.
