Because as I've already stated 8 times previously. We're pitting sub vs. sub. If it were builder vs. builder, there's so many variables that it wouldn't even matter what sub you used. Builder vs. builder would be great, but I definetly do not have the time or money to put into a vehicle that isn't even mine just to prove the already obvious. The only chance a 10 would have is in some special ported enclosure with gobs of power thrown at it...not sure if you guys think this is some secret weapon or something, but what makes you think I couldn't do the same thing with the w7...you really think I'd show up with some prefab sealed box and a 1000w amp if this was the case? Besides the fact, this would be pitting enclosure vs. enclosure. You guys are obviously set on using a ported box because you know it's your only chance in hell.
