Default Which is more important in speaker cables - thickness or lenght?

When you connect a pair of speakers with cables of clearly different
length, the speaker with longer cord will be lower in volume. It makes
sense, the cable 'dissipates' the power in layman's terms or
something.


That's the theory, but in practice it depends on how "clearly"
different the cable lengths are. If you're talking about 10 feet to
one speaker and 1000 feet the other, if they're the same gauge, you
probably will hear a difference in volume. If you're talking 25 and 30
feet, you probably won't hear a difference.

OK. Even I can hear a difference.


In that case, your speaker cables are grossly undersized.

BUT I came to thinking...IF you can't have same lengths no matter
what, which kind of cables would make the difference less noticeable -
thicker or thinner?


Thicker, for sure, assuming you're talking about wire gauge.

But then again, if we use a really thick cable, does it make it easier
for the current to pass to the speaker and translate to less signal
loss


In layman's terms, yes. The resistance of the cable is lower, so less
voltage will be dropped across the cable and most of what comes out of
the amplifier will be available to the speaker.

You can find a copper wire table on the Web that will give you the
resistance in ohms per (usually) thousand feet for a given wire gauge.
You can use Ohm's Law to calculate the power lost inn the cable and
see if it's signinficant.
