I'm thinking about buying an SVS (PB2+) for my garage I'm converting to a home theater. Yes, I know, the flat response is what makes SVS a step (or two or three) above most other subs. But if I want to crank up the volume on some hip hop etc--- a) Will I be able to tune the sub accordingly to get "boomier" on some music and flat all the other time? b) Is there a difference between Box or Cylinder Subs in that one is easier to adjust the tune? c) Would any of the equipment they sell like the equalizer help me achieve this?
