    Bi-amping with one amplifier

    Been researching bi-amping and recently has seen a pair of speaker wires that terminate in two sets of speaker leads in order to bi-wire your speakers. Isn't this just circumventing the crossovers in the speakers themselves? What is the purpose of this?

    Also on the subject of bi-amping, what about using the a&b speaker outputs of the same amplifier? Would this overload the output stage of the amplifier since it's driving twice the load into the same speaker? Is there any benefit of doing it this way as opposed to having four separate amplifier channels?

    Re: Bi-amping with one amplifier

    Welcome to AS.

    The main benefit is to eliminate the jumpers that connect the binding posts. I recently done that and it was a nice improvement. The amp I started with had two sets of binding posts, using both causes no issues. Then I went back to using my amp with only one set of binding posts, with this I ended up just using one set of cables and bought upgraded jumpers from the same brand cables, which is cheaper than buying bi-wired new cables and result theoretically should be the same. I used two seprate sets of cables when I was using the amp with two sets of binding posts.

    Bi-wiring doesn't bypass the crossover. The low end bining posts would have a circuit to cut off frequencies above a certain point and the high end connection cuts below a certain point.

    Technically to true bi-amp there should be no internal crossover in the speaker, or, bypass it, and use an external crossover that would split the signal before it goes t the amplifiers.

    Re: Bi-amping with one amplifier

    Using a Yamaha M60 power amp that has a and b speaker binding posts. So there would be no problem by wiring the speaker using both?

    Re: Bi-amping with one amplifier

    Correct, no issues. You could use two sets of cables going from setB to the speaker low end posts ad A to the high end posts, for example. Be sur to remove the connecters on your speaker, sometimes it's a flat piece of metal going from top to bottom posts and sometimes it's a short piece of cable.

    Post back if you will wih how you like the results.

    Yes, tell us if you notice a difference in dynamics and clarity, bass punchier and tighter.
