    Quoted from wayout440:

    This is an old audiophile trick called "poor man's surround sound". http://monkeyfighter.com/surroundsound.html
    I just don't have enough technical information to advise on changing the impedance of speakers on STLE. Usually, there is a bit of research done to choose a certain design. Even though deviating from the ratings may work, the safest best is to replace with ratings called out in the design.

    Yes mine MET pro is wired the SAME way. In series, but 1 speaker the reverse the polarity.

    in mine cse i have exacly the same:
    2 red/white wires are connected to the left speaker +
    Then from the - of left speaker to one end of this elco, then to the - of right speaker.
    Then 2 red black wires are connected to the + of right speaker.

    In this case they used 2 8ohm 4watt speakers in serie.

    Yes it is in serie, but one speaker is reversed polarity. (surround job?)

    I look in the manual, and there you see. The guys at stern did nog follow the original schematics for series wiring, for some reasons. Dont no why, or it was or wasnot intended to do so in the first case.
    In factory schematics it shows an clear original series wiring, with crossover (elco)

    See olso page 57 of the metallica user manual @ stern website.
