But things begin to change, and rather dramatically. Let's push the M80ti's to what we might experience from a solo grand piano, 109 dB. We're at 96 dB with 10 watts per channel. Let's go to 106 dB. So that requires 10 x 10, or 100 watts. Close, but not quite there yet. Just 3 dB more. Remember, we have to double the power for a 3-dB increase in sound level. So 100 watts becomes 200 watts

So for these old m80s, with the seating position 12 feet away in a standard room, to reach 109db, one would need 200 watts per channel.
And to go from 109 to 119db, you would need 2000 watts per channel. I think the m80s have only been tested as high as 1200-1400 or something, so this is definitely not needed or recommended.
I would like to reach the 110db level comfortably though.
Seems like a good argument for power amps to me tho?
