    I just picked up a pair of Polk Audio RTi4 bookshelf speakers and when I got them home, I discovered they are set up for bi-wiring. I took a quick look at the back of my receiver (Panasonic SA-HE100K) and saw that it has two sets of speaker inputs (A&B.) The Panasonic documentation does not specifically mention bi-wiring but does reference how to set up 2 sets of speakers. Now for my questions...

    Can I bi-wire these speakers using this receiver? Will bi-wiring make a noticable difference? Does the fact that only two speakers out of seven being bi-wired make a difference?

    yes, you can certainly biwire them, but mind you, biwiring does NOT involve using the A+B speaker outputs (outputs, not inputs); that would probably be considered "bi-amping" (arguable), which is probably NOT what you want to do.

    with biwiring, 2 wires are run to each speaker's 2(+) and 2(-) posts from only 1 single receiver (+) and (-) output for each channel.

    biwiring only some speakers is fine.

    will biwiring make a difference? doubtful, but try it. generally, it can't hurt.

    My impression on bi-wiring was to use two seperate amplifiers; one for the woofer, the other for the midrange/tweeter, using an external crossover, et cetera, et cetera.

    Not that I've ever got involved with that.. just my impression.

    no, that is bi-AMPing

    biwiring uses a single amplifier channel per speaker.

    Thanks for the clarification guys. I guess I will just leave well enough alone, since it sounds like with my particular configuration, it will not make a huge difference one way or the other. Thanks again!

    Search the forums for bi-wiring. Specifically, try the Speakers forum, and the Tweaking forums....this forum isn't exactly the one that deals with this stuff. You'll find lots and lots of bi-wiring info there.

    so if we might continue this 'primer' on bi-wiring...

    ...what possible good can bi-wiring do, apart from using, say, 2 runs of 14ga to get the equivalent of 11ga?

    I don't get this.

    search elsewhere, too. you'll find plenty of info about it. none conclusive, mind you.
