The wires are run through the walls right to where the speakers are. I already know its not ideal due to the room layout. The Surround left is much further from MLP then the surround right, and the surround right is only a couple feet away, but its about the best I could do position wise. The subwoofer is basically banished to the corner it's in now, though i can turn it different directions if needed/if it helps. Second, if room treatments are needed, they would need to be done in a VERY creative way since the system is in the shared living room area and WAF is big here. Creative meaning hidden in plain site as decorations or similar.
Based on what you said in step 4 about running MCACC when all is done, wouldn't that override any changed i may have made to crossover, etc?
Yes, along with the speaker trims and sub distance setting (which you may change when doing the sub distance tweak
*), but you would change those values again post-calibration to where they measure best.
You will be surprised how convincing you can be about critical sub placement once you see your graphs.
*The sub distance tweak, Reader's Digest version:
1) Measure CC+subs (all speakers set to small, REW HDMI output CH3, sweep measurement)
2) Note if there is a dip at the crossover point (could be just above/below crossover as well)
3) Adjust subwoofer distance setting in AVR in +1' increments (make sure to back out of the distance setting menu or the changes won't take effect)
5) Repeat steps 3 & 4 until the dip comes up to flat
If your system is mainly movies, step 1 should be CC+subs...if mostly music you should measure FR+subs or FL+subs. If it is an even split, you will need to find a distance setting with the best compromise between mains & center.
