Amplifier-Loudspeaker Matching Formula 1.0

In terms of power, we compare the power of amplifier (watts) by the power handling capacity (watts) of the loudspeaker. Power capacity of the loudspeaker is measured by watts but actually the power of a speaker is measured by sound production capacity, which is measured by decibel (dB). dB does not have linearity with power handling capacity (watts). The electricity signal is transformed to sound energy by loudspeakers. Power handling capacity of the speaker is measured by watts but sound production capability is measured by dB. For instance there are speakers, both of them are 100 Watts. One produces 90 dB (1 mt 1watt) and other produces 93 dB. Second one does provide twice volume of sound by the same power compared the first. By using the program below, you may easily calculate how much dB that you may provide by your system or you may choose your amplifier or speaker in accordance with your demand.
