    Hello,
    Keep in mind the LSi25 doesn't have bi-wire capability. It is a bi-amped speaker when you've connected your receiver or separate power amplifier to it. The two set of binding posts allow the owner to choose either a speaker level input or, removing the binding post jumper plates, a line level input to the internal bass amplifier. Bi-wiring would have meant three sets of binding posts not two.
    Cheers, Ken

    Thanks Ken...Currently use LFE with binding plates removed but would the sounds and tones be different if I wired the sub posts to an amp output

    Hello,
    I don't believe so. The internal amplifier would still be powering the 10" woofer, not the external amplifier. The internal amp would reduce the incoming powered signal to a line level signal then give it to the amp to enlarge and power the woofer.
    If you're feeding a filtered signal to the LFE input, on the speaker, then you're making the best connection. You might want to experiment with changing the sub-out crossover frequency that's coming into the speaker. See how that changes the blending with the woofer and the rest of the speaker and the interaction with the room. You might prefer, say 60Hz instead of 80Hz. Or, maybe 100Hz works better for you.
    Cheers, Ken

    Not a problem, that's what the Forum is for. You've chosen some excellent sounding speakers and I'm sure you'll enjoy them for many years.
    Cheers, Ken
