My old Infinity had a "boom" that I could hear. My new VTF-2 has a "punch" that I can feel. That's the biggest difference I have noticed is that I feel the bass more than hear it now. One thing that really made me notice it is when I was playing Outlaw Golf on my GC over the weekend. When the ball hit the ground the sound was "thhhhump". I didn't realize it was the sub at first because I felt it more than heard it. Thought something fell against the side of the house at first. Point is upgrade from a boom to a punch. You won't regret it.
