Which sub do you recommend? I just ordered Swan Diva 2.1, C-3, and R-3s. The room is 14x14 with 10 foot ceilings and no left wall. I will primarily use this for movies. I don't need to rattle the windows, but I do like a nice, clean, low rumble when watching films. I've narrowed it down to SVS PB1-ISD ($652) or Outlaw LFM-1 ($636). Any suggestions between these two? Or due to the size of the room, do you think I only need a 10" sub like HSU-STF2 or the new SVS PB10-ISD (both on back order for 8 weeks, but $200 less).
