No.  Ethernet packets are a store-and-forward technology.  The delays
are caused by the hardware in the switches and end points that have to
stop, buffer, and analyze each packet, not in the propagation time on
the wire.  With analog speaker wire there is none of that.

In general, the sound will move much much faster electrically on the
wire than it will in air, so any perceived difference in timing will
have much more to do with which speakers your ears are closer to than
any length difference in speaker cabling.
