i've never measured the M80s alone, but these are a few results
i got when playing some movies at Reference Level.

the SPL meter was always set to "peak" and "fast", without filtering (flat response curve in the low frequencies), and the meter sitting at the usual listening distance on an armrest.

300: 118.8 dB
The Pacific: 118.7 dB
Bourne II: 117.0 dB
Bourne III: 118.2 dB
Super 8: 122.3 dB (Train crash, a heart stopper)
Super 8: 119.7 (bus turnover, mainly low frequencies here)
WOTW: 122.4 dB

the highest power output measured was the train crash;
i measured gross Watts used by the M80s amp, which came out to approximately 445 W/ch net going to the speakers after compensating for the amp's efficiency. this is an approximation only, as the Watt meter is not very precise.

under those conditions, the sound is always devoid of audible distortion, which was my principal goal when i bought the audio equipment a few years ago.

I didn't see Tron Legacy there. That was one of the loudest using bass that I've heard, so far in my system.

i don't have Tron Legacy, but the most intense - in time - loudness i heard in a movie is Terminator Salvation.
sounds over 105 dB are heard very very often during the movie, so much so that it is the only movie I've ever heard that desensitized my hearing - for about one hour - post viewing the movie.

i highly doubt i will ever watch that movie again, as i don't like to watch a movie or listen to music at levels below "realistic";
they lose too much of the "artistic intent".

I tend to soften the sound more than I used to in an attempt to help lessen the damage to my hearing.

a few year back when I had my M80Ti and a Denon 3805 and a RS Sound Level meter I hit stupid crazy level of 116db in my 12x 17x8 room. Just to see how loud and a that I din't have the volume knob at full. I think the Denon 3805 is rated 120w 8ohm and 160w 4 ohm.
so 200w wouldn't get any louder, if and why you want it this loud is beyond me.;)

but, if you need it this loud, then as mentioned ^^^^ get a pair of Paraline's and a Paraline subs. these speakers are built for this and I have a set in my muusic room and they are wicked wicked clarity and volume.

Fleetwood Mac had those same speakers at their concert in Vancouver and must have been a dozen or so on each side of the stage. Very Impressive to say the least, just hanging from the sky!

This makes me happy. I just purchased a pair of m80's last month and look forward to getting the rest of the system so I can achieve results like this.

I'll be buying an emotiva xpr-5 for my power needs.

Can you define your usual sitting distance?
The dB measures need to be quantified with that measure otherwise at 1m i would say ho hum but at 20m i would say, holy crap on a cracker.
