Thanks for reply!
Even though I am buying paradigms I found them at a great price, being that they are older models. I am on a pretty tight budget, and I will need a subtantial amount of money for a good reciever like rotel, outlaw, or B&K to power the paradigms. My sub budget then falls to about 400-500, which is why I have these listed. I would love to get a couple Hsu's, I have seem such great stuff about them, however It is not in the works for me right now. I am leaning towards the larger 12" subs, like the infinity SSW212 (dual 12"), but I am unsure if I was passing up any great deals (Like the M&K or Velodynes?)
Also, edit on room size, apparently my powers of estimation are off a bit, it is 11x22. Next house may not be bigger cubic foot wise, but we are looking for something more square-like.
