No I dont, im just stating my opinion and saying that my box was sealed so I wasnt going for spl and the Type Rs where ported and where going for SPL and the FI was louder. So it does help, its helps by 1 more opinion and yes I know he is a SSA Tech and he helps answer alot of thins but he shouldnt go saying peoples posts suck when they are stating an opinion, a sucky post is one that asks how much something costs or if its something you can easily research. The type Rs could be louder than the Q in the proper box but for the average person who is going to buy the sub then throw it in a pre-made box then the result is that the Q is louder. I built my box because it needed to be custom to fit in my trunk and I did not intend for SPL but I intended on SQ. Does that "help shit" for you, that if your running a pre-made box for the typer Rs then the Fi Q 15 will be louder. You are honestly making yourself seem like a dumbass.
