Glenn, as I said in another post, please stop this. You have a
minuscule technical knowledge which ends far short of an ability to
understand and apply Ohm's law, but you persist in airing your
howlers. I know we are all amused when we have nothing better to do,
but you really are doing yourself no favours.
As opposed to you, who has already proved in a previous post that you
have no idea how an earth loop works, interpreted "two signals" to mean
combining a stereo signal onto a single core and couldn't understand the
correlation between "unwanted signal" and "noise" (hint - "noise" is any
"unwanted signal") etc etc.
You've proved your own ineptitude, now please stop foisting your
inadequacies onto me. This is Usenet, not work, and I don't get paid for
doing this. Therefore I'm not going to write a highly detailed analysis
of why bi-wiring does make a difference (and I can assure you it does)
which you've already demonstrated that you won't understand anyway.
Now please go back to your £39.99 micro system purchased from Currys
with speakers linked up with bell wire, and stop pretending you know
anything about hi-fi.
OK - you snipped the substance, as you had no way of dealing with it.
So I will repeat it again:
First lets assume that your experiment is applicable.
Now complete it. Use you second case - with the two wires
run separately right back to the source ( for maximum brightness). Now
take your short piece of wire and join the two bulbs together. If
biwiring made a difference, there should be a change in brightness as
you do this. There is no change. All you have shown is that it is
usually better to have thicker wire.
The second point is that the tweeter and woofer are not in parallel.
Does that surprise you? This because we are dealing with signals in
defined frequency bands, and we have a crossover, which presents a
high impedance to the cable in the stopband of each driver. This means
that low frequency signals - no matter how big - do not suck voltage
away from the tweeter. In fact the tweeter doesn't even know there is
a woofer there. There are of course electrical devices that have the
effect you describe; they are called modulators and rely on controlled
non-linearity to achieve a multiplying function. If you can show that
cables act as modulators, you will have saved the broadcasting
industry a fortune overnight and your fame will be assured.
Now, answer both of those - if you are able. (breath not being held, I
promise).
