Let's do this deciBelicly.
Twenty-two Watts driving a sensitivity of 102dB is the same as 44 watts driving 99 dB...is the same as 88 Watts driving 96dB...is the same as 176 Watts driving 93dB...is the same as 352 watts driving average-sensitivity 90dB speakers. 352 Watts is probably some 100 - 200 Watts MORE than most of us use on 90dB-sensitibity speakers.
I'd say 22 Watts will be 'plenty 'nough'.
