Peak watts (misleading because many will take it as a true measure of the work that the amplifier will do when driving the speakers)
If the manufacturer specifies wattage as 'peak power' they may say that they aren't trying to mislead their customers, but I believe that that is precisely what they are trying to do. They assume that the vast majority of people are going to accept the wattage as the maximum power that the amplifier can produce. If they use peak voltage to derive the peak power, the power specification may be legitimate but it is misleading. The peak power is mathematically twice the RMS power output.
Because most people are dumb enough to believe more = good....It's exactly for this reason that they started making the CES (CEA?) 2006 compliance standards. Those that adhere to this are allegedly stating the true power capabilities of their equipment in a way that is standardized across many different manufacturers. This way you can compare one company to another and know that their power measurement formula is the same.
I usually call these max. ratings "Imaginary Watts"
best response EVA! it is a spec to get the noobs to believe they are getting more than they really are. take a look at what the THD is at that "max" rating. you will see what I mean, lol.Because the output of an amplifier is AC voltage and therefore can be expressed in RMS or Peak (which one they use is all about the marketing of the amplifier).
3 ways of expressing voltage of a common AC wave form
Scroll down and he says this,
320W peak output @ 1% THD, bridged
310W peak x 2 @ 2 ohms; 220W peak x 2 @ 4 ohms
155W RMS (continuous) x 2 @ 2 ohms; 110W RMS (continuous) x 2 @ 4 ohms
