What is a reasonable watt output in speakers?
Speakers do not have a “watt output”. Speakers are rated in terms of the minimum, continuous, and maximum power they can handle, which is expressed in terms of watts (W). The loudness of a speaker is a function of the power input to the speaker from the amplifier and the speaker efficiency. More efficient speakers require less power to reach the same apparent loudness than those that are less efficient. The apparent loudness of a speaker does not have a linear relationship to the power – the relationship is logarithmic: dB value = 10 * log( Power / RefPower ) The human ear can perceive changes of less than 3 dB in volume. An increase of 1.5 dB is barely audible, but requires a power increase of about 41% (e.g., 100 W to 141 W). A 3 dB increase in volume is audible to anyone with normal hearing and requires twice the power (e.g., 100 W to 200 W). This is why there is really no audible difference between, for example, a 90 W amplifier and a 100 W amplifier. The difference in power is les
