Decibels can be used to compare amplifier power, or the output from various amounts of loudspeakers. What you will find with this calculator is that after the first few additional amplifiers, the amount of additional decibels you are adding drops off fast. It makes a much bigger difference to go from a 100 watt amplifier to an 600 watt amplifier, than it does to move up from a 10,000 watt stack of amplifiers to a 20,000 watt stack of amplifiers.
