Ok...this might seem like a REALLY stupid question to all of you people who know much more than I do about subwoofers, but where the hell are the other two drivers inside of the B4+? If I'm not mistaken, there are supposed to be a total of 4 drivers inside of it, am I correct? And two of the drivers can easily be seen at opposite sides of B4+. You can also see how big their magnets are, if you take off that black peice. Just two drivers nearly go from side to side already. Couple that with the four ports which are EXTREMELY deep (practically reaches the other side) and you're left with almost no space what-so-ever to fit another two drivers (same size) as the ones that can be seen at the opposite sides. I'm guessing that we're left with about 8 inches of space (after the ports end) in order to fit more stuff, but the drivers are 12" right? Maybe I'm just mistaken. Perhaps there are only two drivers in this thing. I can hardly believe that there is any room for all 4 drivers in there.
