well I personally like the older w6's myself. I was running 3-10w6's off of my PPI A600.2 about two years ago and I loved it sounded fantastic but didnt have the depth that I wanted if punched like a mofo but didnt slam those lows that I wanted. Then I went to the newer 12w6v2 and I was much happier with the old style 10w6's then the new w6v2.
