Yes, it sure can. The cooling plug works just as well in a direct radiator as it does in a horn. It will provide twice the power handling ability when used in a direct radiating subwoofer.
The thing about basshorns is they reduce excursion and thereby decrease the cooling vent's effectiveness. So to me, this makes it even more important (mandatory) that a cooling plug be used in a basshorn application.
