It really depends on what amp you have, what type of music you listen to most, and how much space you are willing to sacrifice for a box.

If you want the tightest most accurate bass with good impact and decent low end extension but want this smallest box possible, go 0.75ft^3 sealed. Because this will not be very efficient, this box will sound best with 750 Wrms or more.

If you want the powerfull bass with great low end extension but are willing to sacrifice some accuracy, then go 1.5-2.0ft^3 ported tuned about 35-40hz and at least 24in^2 of port area. The bigger the ported box will result in more efficiency and more output near tuning. This box will be efficient enough to run on 500Wrms or so but will also slam with 750 Wrms or more.
