1.After the basis full auto MCACC setup how do we proceed to The Advanced MCACC?
2.Do we set the speakers size first then MCACC or after MCACC then set speaker size?
I did the auto MCACC, the speakers size always come out Large even I’m using KEF3005SE which are small 5.1 speakers.

After setting to small,when I run MCACC again it sets it back to large.
3. What is the best sub crossover for a small room of 11’X14’, any how my input is 100HZ..any help in this area?
4. Another thing is, it sometime show my center speaker as Reverse Phase even the speaker are properly connected, it drive me nuts

.…I just ignore it and proceed with the calibration...

Try this link I just came across. Might not answer all your questions but may be able to enlighten us more on MCACC. The rest is up to us to experiment and get the 'best' setup for our system.
