Just bought my 1st SVS sub, I hope you guys are right about how good they are. I bought the 2531pci I hope its big enough my room is 13ft by 23ft with 1 entry way and has 8ft ceilings. I live in a townhome so I can't get to crazy. I thought I would get a free t-shirt but didn't read anything about getting one with my sub purchase. Oh well.
