    I just bought the Sound & Vision DVD and am trying to adjust my sub level according to their test tone, but it seems no matter where I turn the sub's volume control, it reads the same on the SPL meter. How can this be? I turn the master volume to a comfortable listening position like the DVD says, but the left channel won't even show up on the SPL meter unless I crank the master volume up really loud which causes the sub to get too loud, even when both the volume knob and the volume levels in the receiver are as low as they can go.

    So what you're saying is that you can't get the left tone to show on the meter unless the master is very high and then the sub is excessive?

    Is this true for all channels or just left (does right channel show up on the meter with the master at "normal" level, do the rears? Or does the master have to be "cranked" for all main channels)?

    If the sub output on your receiver doesnt change the output of the sub, have you tried adjusting on the sub itself? Are you sure you're using the correct control in the receiver menus for the sub output?

    Analog SPL meters tend to get stuck sometimes, this happened to me several times. The meter somehow gets stuck but not totally, it kind of loses its sensitivity. Shaking it gets it back in shape.

    I once had an energy sub that had a separate input jack for crossover bypass. When using this jack, the sub's volume knob was also bypassed.

    I would try changing the weighting of the meter too, especially if it's analog meter.
