I have been looking at subs for a while now and after reading Hsu with every mention of subs, I have decided that I want one. My question is whether or not I want the VTF-2 MK 2 or the STF-3? The vtf is $100 cheaper so that is a plus, but I think I might like the 12 inch sub of the stf-3! Anyone out there compare the two? Any input is appreciated. Thanks in advance
