    Its to see if you have a drop off in bass around your chosen cutoff frequency. If you have the cutoff set too low you´ll get a "gap" in the bass between your main speakers and when the sub takes over. Its also handy to see (hear!) how far low your systems bass extends.

    For proper calibration use either AVIA or Video Essentials test discs.

    AVIA available here:

    Video Essentials here:

    cheers
