TEACH ME ABOUT BI-WIRE

Nobody is more skeptical of bi-wiring than I am. Even the designer of my speakers, who put bi-wire terminals on the speakers, doesn't really support the idea.

But, but. For some strange reason that has no logical basis in science my speakers sound better traditionally bi-ired than non-biwired using the same amount of wire or bi-wired using the Jon Risch "tweak" mentioned above. Even my little spl meter thinks the bass is better (more of it). But the treble is also clearer, and that just generally makes for better imaging as well as a purer sound and tighter bass.

So, try it. What's the harm?

70242, it's the interaction of the woofer & tweeter w/the amplifier that i'm referring to, - bi-wiring puts distance between these interactions, making them happen closer to the amp, not to the speaker.

Sedond: The crossover reduces the interaction between the woofer and tweeter. Any back EMF produced by the woofer will be absorbed by the amplifier and rejected by the tweeter side of the crossover network, as it should be. Adding wire will not help this process.

702, i don't doubt what yure saying, but emf produced by the woofer, absorbed by the amplifier, & rejected by the tweeter's side of the x-over network, is going thru more wire from woof-to-amp-to-tweet, & when going to amp, the tweet isn't seeing signal fighting the emf coming at it.

look, i'm no scientist, yust looking for logical info as to why it sounds better. see also, paulwp's experience - even his spl tinks it's better... ;~)

don't tell me it doesn't sound better yust cuz there's no logic in it for *ewe*. it *does* sound better, please help me figure out why.

Sedond, you've got part of it. But the tweeter's side of the crossover network is a very high impedance--typically several kilohms--to the woofer's back EMF, while the amplifier is a very low impedance, typically several milliohms. That means that the tweeter network is going to reject the woofer's back EMF, and the amplifier will absorb it, regardless of the extra wire. It's like pouring water on the side of an incline; it's going to flow downhill (the low impedance path) instead of uphill (the high impedance path), and you don't need to do anything extra to make the water not flow uphill.

To improve the amplifier's absorption of the back EMF (better known as damping), you should provide a path between woofer and amplifier that is as low in resistance as possible. That would entail wire with large conductors. Alternatively, you could place the jumpers on the speaker terminals, and thus use doubled-up conductors, which would provide the same benefit as using wire 3 AWG larger.
