so a speaker with a sensitivity of 93dB @ 1w / 1 meter means 1 watt of
power will drive an input signal at 1khz (sine wave?) to a spl of 93db
at 1 meter?

but isn't a 1khz test tone unrealistic? wouldn't pink noise be a far
better test? and wouldn't pink noise require a lot more power for the
same volume?

and couldn't i figure out how much power i need in an amp much better
if pink noise was used?

the other number is the power range or rating. that is supposed to say
how much power the speaker can handle before it erupts? and then on
the low side the practical minimum required to drive it?
