    Here is my system....
    *Receiver...Onkyo TX-SR600 6.1
    *Mains...JBL S38 II
    *Center...JBL S-Center
    *Surrounds...JBL N24
    *Sub...Sony SA-WM40
    My question is ...What should I have my Subwoofer set to (80-100-or 120 Hz) in "Speaker Config" if I have all my speakers set at SMALL?...Once I set it, on the back of my Sub should I have my "Cut off Frequency" dialed in to about the same setting ?
    What about the "Phase" switch on the Sub?? should it be normal or reverse??

    Thanks for any help,

    Check out this thread, it has the info you are after. Here is a cut and paste of some info Edward JM posted on it:

    There are common set-up errors that could be causing some problems. Double check all of these things before you try to recalibrate:

    In the AVR:

    1) All speakers set to small.
    2) Crossover set to 80 Hz.
    3) Sub set to on/yes.
    4) Subwoofer Remix or LFE + Mains set to off/no.
    5) Dolby Dynamic Range Compression Circuit set to off/no.
    6) LFE (0.1) channel level set to maximum (i.e., unattenuated) value (if the AVR has the capability).
    7) THX (or any other) bass limiter circuits set to off/no.
    8) Subwoofer channel level to -5.

    In the DVD player:

    1) Output set to bitstream (digital output via the digital coax).
    2) Dolby Dynamic Range Compression Circuit set to off/no.

    On the subwoofer:

    1) PB2 to all ports open (we can try 20 Hz tune later).
    2) Tune switch to 25 Hz.
    3) Crossover switch to off.
    4) Set the phase to 0 degrees initially unless you have the capability to evaluate the FR of the system.
