My 100's do best set at large. I know most say cross over at 80 but going back and forth I really think the 100's are why there is even a large setting to begin with.

My 100s do best at my thief of a friend's place.

I need walls. Everything sounds great but I really have to crank movies up to really enjoy it. Music is dialed in for stereo and surround. I didn't have to change anything but the toe in. Used my line laser to see exactly where the sound was passing the MLP. Reduced toe in to point beyond the outside edges of the couch and I have great sound no matter where I'm sitting now. Running the speakers at 40hz right now and so far I'm really enjoying them.

Insulation and drywall on your concrete won't make it any louder. Is your MLP 16 feet? What volume is the Denon at when you crank it? How many dB did the Denon set the M100s to during calibration?

My LFR's are set to LARGE and I also send the base to the subs ...

LCR speakers are fine and the the one surround is mounted to header but the left surround is hanging on a stud on a blank wall so it doesn't have anything behind it to help with reflection. MLP is 16 feet. I believe the DB correction is 3.5 or 4 on the fronts the left surround is +8.5 and the right surround is +3. Denon is at -5.0 on movies. Music is between -15 to -10.

If the dB correction is 4 on the fronts, at -5 on movies your fronts are at -1. That is at the RMS limit of your Denon. Peaks may actually be getting compressed by the Denon's dynamic compression circuits.

-15 to -10 on music is more like -11 to -6 given the 4 dB correction on the front. Depending on the music you listen to, it may also be getting dynamically compressed by the Denon.

I'm not surprised by the way given your listening distance.

As for the surrounds, note how the one hanging by the stud is offset by much more compared to the other. I wonder if those channels are also getting dynamically compressed during movies.

Would adding the ada1500 fix any possible compression with the higher power output?

Front left is +3 right is 2.5 center 5.5
Left surround 8.5 right surround 4

Oh yeah! You bet it would. You'd never run out of power. The dynamics would be limited by your M100s but practically, you'd never run into that limitation.

I switched the avr back to 5.1 bi amp off of 7.1/zone 2 and that seems to have cleaned up the sound quite a bit.
