[QUOTE="Timber_MG, post: 24664, member: 18"] Clipping doesn't do much to the woofer, it is the ways higher up that suffer from the higher frequency power of a clipped waveform. Most speaker drivers usually die of thermal failiure (on tweeters the voice coil likely delaminates on current models, in the past the lead wires were also prone to stress failure and it does still happen. The crossover's HP filter should prevent the tweeter from dying due to over-excursion and clipping doesn't do much to drastically alter woofer motion (though very deep clipping can cause a slight bias in the cone's dynamic resting position in PA applications, unlikely that that would occur in hifi) As to cone travel...that is dictated by what is on the input terminals of the driver and whether a 20W or a 1kW amp drives 20W into the driver matters very little providing the amplifier is still clean (most SS amps have the lowest distortion just before their power limit) [/QUOTE]
