I need to get my parents a subwoofer for their home theater. I'm basically trying to spend about $200 on each speaker set ($200 for the center, $200 for the fronts, $200 for the rears, and $200 for the sub), and I'm looking at getting used speakers to get the best bang for the buck. I've come across a couple of subwoofers that I think might do the trick and be in the right price range - the PSW303 and the PSW10. I'm wondering which you guys think would be best for a 12' x 15' room that is open on two sides to other rooms. They will mainly watch movies and TV.
Or do I really need to convince them to shell out the extra $ for a PSW505 or something like that?
