Hi,
Can you please tell me the advantages and disadvantages of 4 ohm
compared to 8 ohm loudspeakers?
Depends entirely on the speakers in question, the equipment you use them
with, and your personal tasts/circumstances.
The only general comment is that *for the same applied voltage* the 4 Ohm
ones may draw more current, and that some amplifiers may not like this.
By the way, some manufacturers offer near-identical speakers in 4-ohm and
8-ohm versions, with otherwise similar specifications.. Does anyone know
how they do this ... is there some simple trick to it?

Fewer turns of thicker wire on the 4 ohm unit.
