I am currently a college student living in a smallish apartment, so obviously money is an issue. I currently have a Sony STR-DA777ES Receiver, with Paradigm Titans as fronts. I currently ran into some extra money so I'm looking to buy by first sub. My main two options at the moment are the Paradigm PDR-8 or PDR-10. I'm looking to keep it in the $300-$350 range, although if there is a better option for less, obviously the better. So lets hear some opinions.
