TOA Product Knowledge: Calculating Wattage Required

It is fairly easy to calculate the on axis amount of power required to a speaker if we understand and apply a few basic principles.

  • Sensitivity
  • Power Increase vs. SPL
  • Loss of Sound Pressure over Distance
  • Typical Sound Levels


Having this information makes it relatively easy to estimate how much power is required per speaker for a given listening distance. No wasted amplifier power and no complicated math required. Click here to learn how to apply these few basic principles.
