If all these numbers mean nothing as yall keep saying, then whats the use of them? Seems like everytime some asks about it, the same response is don't use the numbers....
OK, the rule is generally don't pay attention to
wattage numbers.
This is because:
- for receivers, the companies tend to fudge the numbers in various ways so you can't directly compare anyway, you get less than advertised. Despite this, for home usage with typical speakers and listening volumes that won't cause permanent hearing damage, you are basically guaranteed to have enough power.
- for speakers, again you'll tend to blow out your hearing before reaching a power level that can damage the drivers.
- in general, small differences in wattage aren't very meaningful, because you have to double the power to get a +3dB increase in volume, which is "turn the volume up a bit".
exceptions:
- you are putting on a concert and need to blast away at loud levels in a huge gymnasium/auditorium or the like.
- you have exotic low impedance speakers like the Magneplanars someone was having trouble powering in another thread.
The numbers for speakers you tend to look at are frequency response, particularly at the low end, sensitivity, impedance. And driver sizes + overall size. Not anything to do with watts.
