This calculator is designed to give the total amount of decibels
change you can expect with a gain of wattage from different
speakers. Enter the data and click on calculate. Decibels can also
be a benchmark of amplifier power, or the combined output from
various numbers of loudspeakers. The summary is that the first 200
watts is the most important in real life applications and that
addition or alteration thereafter produces proportionate but
diminishing returns. It makes a much bigger live difference to go
from a 100 watt amplifier to an 500 watt amplifier, than it does to
move up from a 1000 watt bank of amplifiers to a 5000 watt bank of
amplifiers, though the decibel change is the same. The first
application would be very obvious while the second would hardly be
detectable.
