Hi, I have my Tannoy 625 ALFie sub and am considering upgrading it My kit is Pioneer DVD 656 Player Sony 930 AV Amp B&W DM 604 Floorstanders B&W DM602 Rears B&W LCR60 Centre Panasonic 32 PB50 Tv Should I go for the B&W Sub or Velodyne or a REL or stick with my Tannoy. It's an oldie - but a goodie. Has anyone heard it? There's not much on the internet about this sub. Any advice appreciated.
