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.
