That Alpha 15 needs a really large box. You could go with 8.0ft3, but tune it very low, like 10Hz - 15Hz, no kidding. I used to make a 12 cubic foot cabinet for them tuned low like that and it sounded pretty good. There's a swell in bass between 50 and 100Hz about 3-5dB, so it's best used in very large rooms or outdoors. It will overload a small room, so if the room is small, go for a Delta 15 instead.
