IN SERIES DRIVER WIRING, unspoken issue?

[smarino11214]

As newbie, saying hello to all.....

I am looking for others take on what seems to be non-essential or
is plainly avoided with regards to series wiring.

In-Series wiring:

Can anyone agree there is time lag automatically inherited to the second in-line
driver since electrons must first pass through the first speakers coil + (push) ?


This is exploring nano-time lag Vs. phase cancellation effect and
critical to line-array driver coupling.

Best to all,
Sal

Electricity travels at very close to the speed of light through a wire. That's near 983,571,056 feet per second. Delay from one driver to the next is not an issue.

The time lag would be so infinitesimal as to be inaudible, much like a fart in a hurricane or worrying about a dime in your pocket slowing down your car. Your bigger issue would be the combined impedance swings.

Good answer!

Also, consider this, the 2nd speaker is still connected to ground, and you drive the speakers with an AC signal. If there were any time lag, the 2nd speaker would see it on the positive part of the cycle, yet the first speaker would see it on the negative part of the cycle.

Short answer: Nope, time lag in series connection is absolutely negligible.

It depends on how many speakers you are trying to wire in series? Eventually, after a number of drivers are added, your sound field will become distorted due to phase errors.

But, are you saying the phase errors arise due to the inductance of the voice coils?

Light travels at 3×10[SUP]8[/SUP] meters/second. Let's assume for the sake of discussion that electricity travels at about half that speed in copper wire.

Now for two drivers, producing sound at 1000 Hz, to be 180° out of phase with each other, the sound would have to be delayed by half a cycle.

At 1000 Hz (cycles/second), the inverse is 10[SUP]-3[/SUP] seconds/cycle or 0.5 millisecond/cycle.

How long with that wire have to be for those electrons to travel 0.5 msec?

You do the math .

The only thing that will change is the impedence. The flow of current in both will be instantaneous.

Yes, thats exactly it. Now mind you it will take a lot of drivers wired in series to do this but it will be an eventuality.

Speaker voice coils do have inductance, but just how much can vary because they move with the musical signal. Just another reason to avoid wiring similar drivers in series with each other.

Because this thread is about how many angels can dance on a pin head, I pointed this out only to say that the size of the dance floor varies, as do the number of angels dancing .
