Some of the best sounding subs are sealed, so it's not a matter of ported vs sealed being better, they both have their own tradeoffs depending on what the designer is compromising. There are examples of great subs from either type. If you look at some of the larger sealed subs, they have little to apologize for in terms of output and extension. The ported subs can dig deeper but they may do so at the expense of other parameters in the mid band or elsewhere.
