Je hoort hier zo vaak : 'Ik heb 2 x 200 watt, de buren hebben niks dan last van mij !!!' en 'Ik
heb dikke 2 x 400 watt Marquant speakers !'. MAAR WATTS ZEGGEN WEINIG !!!!
Dit vind ik een heel mooi en verhelderend stukje over vermogens :
Korte samenvatting :
Je kan zeggen dat je speakers 200 watt rms zijn, of 8000000 watt piek, maar er is helemaal geen term om vermogen voor speakers echt aan te geven. Ook zeggen watts niets over hoe hard iets gaat, iig niet zonder de gevoeligheid van de speakers.

Van de Boston Acoustics site eplukt bij de FAQ voor hun pc speakers.Q. What is the wattage of your systems?
A. Boston Acoustics does not rate their computer "systems" in wattage for two reasons. First, there is no universally adopted standard for measuring undistorted amplifier wattage in closed system like a multimedia speaker system. It is possible to purchase a no-name multimedia system that claims 800 watts for $39.95 that does not come close to the sound quality and output of a name brand system. Boston Acoustics does not play the misleading numbers game.
Second, when you design a multimedia system there are two factors that determine sound quality and output. One is the amplifier wattage (which we already know can be misleading) the other is the quality and design of the speakers. Boston has been designing and manufacturing speakers for over 22 years. Because of our advanced computer design capabilities and tight manufacturing tolerances, our speakers are very efficient; that is, they require very little power to play very loud and clean. Just saying how many watts a system has without also giving the speakers efficiency is like giving the horsepower of an engine without also giving the vehicles weight. You need both pieces of information to make a good judgment. After all, 300 horsepower in a sleek, lightweight sports car will go really fast. But that same 300 horsepower wont even budge the Space Shuttle off its launch pad. So you can see that just giving the watts by itself doesnt tell you much about how loud and clean the system will play. Thats why we give the Sound Pressure Level (SPL) measurement. What is really important is how loud the sum of all parts will play without distortion. It is for these reasons that you should always compare computer systems based on total output or SPL.
The BA 635 for example is capable of achieving an SPL of 96dB. This output is equivalent to a train passing right in front of you. The BA7500 has a maximum SPL 107dB (louder than most commercial movie theaters. Wow!).
