    What exactly does the PHASE Forward and Reverse button
    do on most powered subs?

    It's a phase reversal switch and can be switched to help the subwoofer integrate with the main speakers better.
    Have somebody flip the switch as you sit in the listening position and keep it where it sounds the best and blends with the mains the best.

    To be a bit overly technically correct, it is a POLARITY switch, not a phase switch. A continuously variable knob is adjusting PHASE, but a two position switch is generally just flipping polarity which results in what is effectively a 180 degree phase shift.

    Technically the button has the word PHASE above it.

    It may have PHASE written above it but Mark is still correct, technically.[​IMG]

    Right, Mark is technically correct. I'm sure they put "Phase" on the amp because more people are used to seeing it rather than "Polarity".

    Polarity is a really neat word. Think how cool it would be to have a mysterious button that is labeled POLARITY in somewhere in your home.

    What would it control? [​IMG]

    Gravity, light/dark, vacuum/pressure, electrons being negatively charged/protons being positively charged, etc.

    Some of those would get you killed really fast. [​IMG]

    Is neat to think about.
