Hi all, Today i bought a Velodyne CHT-10 10" Subwoofer. I just want to make sure i made the proper decision. My friend who works at future shop is storing it there for me until i move into my house in 7 days so i have the option of getting the 12" if i'm not sure about the 10". I just want to get peoples opinion's if the 10" is good enough or if i should upgrade to the 12"? Will there be a big difference between the 10 and 12? What are the pros and cons? I'm so new to all this i have no idea! My basement is 19 feet by 14 feet....hope that helps with some imput. The rest of my system is: Pioneer 563A DVD Yamaha HTR 5650 Toshiba 65" WD HX JBL speakers. I really don't know anything about this stuff and would love any input. I don't want to make the wrong decision and regret it in a year....wishing i actually bought the 12" Thanks a ton guys.
