This tool is intended for you to check if your loudspeakers are powerful enough for the desired application. You will need your loudspeaker data sheet to find the required information.
  • 1.) Insert the sensitivity of the loudspeaker. This will be given as a figure in decibels 1 Watt, 1 metre.
  • 2.) Insert the maximum power handling of the loudspeaker in Watts.
  • 3.) Insert the distance you wish the loudspeaker to throw in metres. Remember this is to the height of people’s ears, not necessarily to the floor.
  • 4.) Insert the desired listening level in decibels.
  • 5.) Click calculate.
The calculator will tell you if the loudspeaker is capable of the job or if attempting to reach that level will overload it.
