@David A I agree with you about Fletcher-Munson, if the purpose of the calculator is to tell you the sound pressure level for a given power input (which, to be fair, is all it claims to do). However I think it's still true to say that that doesn't tell you everything you might need to know about the perceived sound level.
I do still maintain that the result of the calculation is based on an assumption of sine wave input, though, because (as I understand it) that is how loudspeaker sensitivity is measured - the sensitivity is quoted for sine wave input at one or more specific frequencies so the calculator will only produce accurate results for that input.
