Could "Amplifier Requirements" be the answer to your question?

If not, it depends on you, how many W the amplifier needs, because you decide how loud you want the loudspeaker to become. You need 125 W to achieve the maximum output, because 111 dB - 90 dB = 21 dB and 21 dB more means 125 times more power.
But you may not want to achieve that sound pressure level, because you have neighbors or because you never listen that loudly or for whatever other reason. You may even become happy with less than 15 W. You will just have to try.
