I am going to have a pair of Polk monitor 40 fronts, cs1 center, monitor 30 rears and either a pioneer vsx 520 or 820 receiver. My room is about 17x12 with vaulted ceilings, but is in an apartment so I can't crank the bass too high. My budget is $175 shipped. My first two thoughts were the bic America f12 and v1020. Do you think I need the power of the f12 or would the v1020 be fine for my space? Is there another sub that would work? Also does front firing vs. Down firing make a difference? Use will be 80% movies, 15% gaming, 5% music. I also saw that the V1220 was a bit cheaper than the F12, is there that big a difference between the two?
