I went through this site http://www.soundandvisionmag.com/spe...tem-page2.html which says

Nominal impedance for the L820 and LC2 measured unusually low at 4.3 and 4.4 ohms, respectively something to note when matching them with an amplifier or receiver.
Is lower impedence than the rated impedence a good or a bad thing?

How does impedence fit into the calculation? Some amps say power is X WPC at 4 ohms, while Y WPC at 8 ohms, where X > Y. Does it mean that speakers with lower impedence can be used with a less powerful amp, and hence better return on investment?
