    HZ (hertz) is frequency. The lower the number, the the lower the tone.

    Hz is literally "cycles per second" of a waveform. This is a bit of complex concept, so I would guess that if you don't know what it is, its applications won't be very useful to you either.

    Do a web search for hertz, you find literally millions of documents explaining it.

    Sounds about right.

    There should be a crossover setting the the receiver and often one on the subwoofer as well (the "cut off freq" you mentioned above).

    If you have both controls, it's best to set the one in the receiver, and then turn the one on the sub all the way UP in order to not interfere with the version in the receiver. So if you have two, set the receiver one and turn the one on the sub to its highest position.

    turning the CUT OFF SWITCH all the way on the sub would turn off the cut of switch?

    yes my receiver has the cut off switch also I set that to 80hz?

    Turning the crossover up to the max will not turn off
    the crossover. But what it will do is keep the
    subwoofers built in crossover from influencing the
    recievers crossover (what Vince said above).

    80hz will probably be a fine place for you to start.

    Good luck.
