Man I bought a pre fab ported box. It was well made no doubt. 3/4 MDF, 45's on the inside, spring loaded terminals all the works... But tuned S O O O high, it was ridiculous!!!
It was made by audioenhancers.com
If your subs will run sealed, and this is only going to be for a month or so, then that's what I would do, most sealed boxes sound pretty decent... But I'm a noob.
