How can you make such a statement not knowing what the listening habits of the OP are?



I'm assuming the poster is not hard of hearing and that the room is quiet (50dB of ambient noise or better).

One M22 requires 1 Watt to produce 93dB at 3 feet. If the poster sits 9 feet away from the M22s, 1 Watt will result in 84dB from a single M22 or 87dB from two M22s. Given that it's a 100W amp, this will give the poster more than 18dB of headroom. And this doesn't count all of the other channels which could result in even more SPL.

I'm in a room that is about 2.5 times the volume posted and my 90W amp is more than enough even when I listen to classical which is quite dynamic.
