Why do speakers recommend amp wattage?


My Usher speakers recommend am amp with 80 watts per channel. Ive heard amp wattages differ significantly, so why bother with a recommended wattage? What would happen if I used 200 watt mono amps (obviously overkill), or a 7 watt tube amp? Thanks.

Nice thread. I was also curious about the wattage.

What is the importance of "current" in amperes? I have seen specs of amps with wattage but different current output. For eg. one amp had 200 Watts per channel and gave 60 amperes where as another gave 200 Watts but 45 amperes.

Thanks,
