Well the holiday season is here and I'm gettin my sub for Xmas. The room to be used is about 14' X 12' and I was lookin at the SVS psb-10 and 12. From posts I've read the 10 should be fine for the room now but I am looking to buy a new house within the year and I would like a larger living room so I don't want to undershoot the sub size. If I get a larger living room can I just double up the PSb-10's in the future or will I be losing out a lot by not getting the 12's. Any help would be great.
