It will depend on your definition of "best".

It could mean loudest, best sound quality, best at handling the lowest notes. . . a lot of other things.

Different subs are designed for different things. You're going to have to ask a more specific question. If someone were to ask, "which vehicle is best?", you couldn't just say Lamborghini, or Jeep, or Peterbilt or anything helpful without knowing what they are trying to do.

Different people have there own opinion on BEST! But if you looking for quality try memphis , kicker etc... For some thing thats gone get low and beat hard try sundown, Fi, Kicker l5-l7s, DB Drive, Rockford can go both ways.
