This is the classic audiophile question. As stated above, in the vast majority of cases, speakers are damaged by an underpowered amp, as opposed to an overpowered one. When the amplifier is driven into clipping, it puts out a square wave(a "clipped" sinewave), which is extremely destructive. A lot of electrical components in other industries are life tested by square wave testing. In a speaker, the voice coil of the tweeter gets fried. Too much power bottoms out lower frequency drivers(as Rockvirgo stated), and you will sure turn down the volume fast. Don't worry about the amp being too powerful for the speakers.
Will my speakers be damaged if I use
hello, Will my speakers be damaged if I use higher power than it can handle? My speaker can handle max 125W (manufacture recommend 25W-100W), but I want to buy used amp from a friend which is 200W. So, do you think my speaker will blow up if I use 200W. Thank you very much DT
