Can anyone that has heard or demo'd both subwoofers please voice an opinion. I can't decide between the two. They both cost roughly the same amount new but I can get a pretty good deal on a used VTF-3. Would I notice a distinct difference between the two. I know that they are both great subwoofers and I don't want to start HSU vs. SVS war but I am really on the fence this time. The subwoofer would be used for 85% HT and 15% music. Any advice would be greatly appreciated. Thx in advance.
