I don't see why not. I'm not sure about going ported with it though since the reason it gets as loud as it does is because of the passive radiator and I don't think you could use it with a ported setup.
Best thing to do would be to get a different setup if you are not happy with it, infinity spent some time getting the most output they could out of such a small design and I doubt you could make it sound much better using your own enclosure.
