[QUOTE="Lasherž, post: 8711672, member: 679555"] Good branded speakers often do outperform their rating, but it's not a reliable metric. The reason almost every speaker fails is heat, dirty power (distortion) causes heat, that's true, but there's more that goes into it. It can play one song just fine but blow on the next one depending on the frequencies. If you think of the cooling method of a speaker it uses vents to **** and push air over the voice coil. If there's less movement there's less cooling. The worst situation is where it clips, this means that despite putting more power into the speaker, its excursion is halted at the peak of the wave and no venting is taking place. In this case there's a decent chance it'll be fine with most songs at that elevated power, but if it hits a low note I have no confidence that it will be able to a) avoid overexcursion with a recommended enclosure (ported) or b) be able to vent away more than its rating in heat with an air dampening setup (sealed). More basic information on damaging speakers and under/over-driving speakers. [URL unfurl="true"]http://www.bcae1.com/2ltlpwr.htm[/URL] [/QUOTE]
