Pioneer's exclusive Multi-Channel Acoustic Calibration system (MCACC). I finally bought a Pioneer SC-27 AVR instead of the Marantz SR6500 i said on a previous post. Anyway this is a heavy unit and so far this is a pretty good match with my Axiom speaker. The MCACC is maybe not the Auddysey from other brand. Some say Auddysey is a class of is own. But i read many good review from the pioneer MCACC one. Took about 3mins and evething is set and ready to play.
I have a small room. 12x11x8. The speaker needed a 7.5-dB boost at 250 Hz and a 9-dB cut at 50 Hz to bring it in line with the Axiom speakers. But the only part i am not sure of is that it set my front and center to LARGE. I know nobody here will tell me to put any speaker set to large (Even the M80) But again, i wonder if i should thrust it. I have not made A-B test but still wonder if i should leave it.

It is the receiver mfg that sets a speaker to small or large, not the setup feature. Correction tools like Audyssey and others measure the speaker (in Audyssey's case the -3dB point) and report it back to the manufacturer. For Audyssey if a speaker measures a 40hz or better -3dB point then it usually is set to Large.
Anyway, to answer your question, you still want to change those to "small" since you have a subwoofer in the mix.

I've had good luck with MCACC myself, but as the knighted duck said, set the speakers to small...
Good luck and enjoy...

Yup. My 45TX used to set my M22's to large. Set them to small and MCACC works fine. Others will suggest using the SPL, which may give better results but I was always happy w/ MCACC.

Same here. Sound is much better with MCACC. I've experimented with just adjusting the built-in equalizer, but overall, MCACC setting is best. Turned off with music, makes it a little lifeless at times. Since there's only one mic position, I usually just put it on a tripod in the center of the room at seated ear level, then try and turn the cat off. She meows a lot.

I have set the mic at my usual listening position. Should i put it in the center of the room ?

if this program does not require taking many measurements at different positions like Odyssey, then i think the only place you should put the microphone is exactly where your ears will be doing the listening (middle of the head). it seems logical to me, as the sound will then be equalized where you do your listening, not in a spot where it will not do anything positive to your listening spot. doing it in the middle of the room will most probably make it worse at your listening spot. dips and peaks change all the time when one moves around in a room; if you want to hear what it does, send a 1 or 2 kHz tone through one speaker and then slowly walk around in the room while listening to the tone. you'll be surprised.
to be sure, try both and listen for a couple of days before you decide which is the better one.

if you don't change the speaker settings to "small", you will end up with double bass where the M80's and EP350's frequencies overlap.

here's a comment by the person who made the test, it can be seen at the end of the test posted above this one.
"2) I think the main thing to keep in mind is that MCACC and Audyssey are designed very differently. Where Audyssey MultiEQ (what I typically use) will take multiple measurement locations to try to correct for a wide variety of locations, MCACC only tried to correct for a single location in the room, which might be at the expense of other locations. Talking to Pioneer they thought that most people would use a receiver such as this in this way (solo listening to music, or watching TV or film), and that they don't have the processor power to be able to do real time room correction for multiple seats at once right now (this could change in the future)."
the important thing here is when he says:"...which might be at the expense of other locations"; this is why i think the mike should be set at the listening position (middle of the head position); if not done this way, it could compromise the quality of the resulting sound.
