    Hello dennistmence,
    Welcome to Polk's forum. The SDA technology places a common ground connection between the left and right speakers. This is from the owner's manual for the X250.5:

    "Some powered subwoofers require an audio signal ground reference and their makers may suggest that a black speaker terminal is where this voltage reference might be found. On complementary designs, which would be typical of all power amps produced by Pass LaboratoriesTM, this is an incorrect and unsafe assumption. On all Pass LaboratoriesTM power amplifiers a reference of 0 volts will be found only at pin 1 of the XLR input or at the shell of the RCA input.
    Reference connections for these devices require special consideration when used with our product. If you have such a device, and wish to use it with our product, please contact our Foresthill, California factory for specific instructions.... you have been warned."

    They are referencing a type of subwoofer connection, but the description is the same, I would contact Pass Labs to know for sure.
    Regards, Ken
