Yes, & not quite. A small port to one side certainly retains much more reso head involvement & head sustain than one in the middle, but a middle ported reso head offers a more rounded focus & more tone in the attack than a bass drum with no reso at all. A centre hole means pretty much relying on the batter head for any sustain, but that can work well in both recording & live mic scenarios in higher powered music.
