1 - Subs in center

2 - Subs in corner

3 - Subs close to MPL opposite to each other by side walls.

Once I figured out the best location for subs, I took measurements with different phases. The reason I did that was to clear our if changes phases makes a difference with and without Audyssey. Now instead of posting many graphs, I'll post the best results for comparison.

1 - Subs without Audyssey in Center/Corner/Near MPL. For subs only, it turned out that phase180 gave better result than phase 0. Also above 70, graph dips.

Phase 0

Phase 180

So the best result is subs in center with phase 180.

Now let's fix that above 70 by bringing in Left and Right speakers. Here I'm going to show you the best results instead of all others.

Now this fixes the 70 and above.

Finally we are going to integrate Audyssey. Here I'm going to show best results with best combinations of phase and distance. I used 3 positions instead of 8 during audyssey calibration. I also took readings on phase 0 with distances of default set by Audyssey and then with increasing distance by 1 and then 2 and then 3. Phase at angle 0 gave me best result . So this comparison is with phases of 225,0,180.

So this result shows that even though with subs only phase 180 gave best result, after running Audyssey, phase 0 with change of distance (adding 1 to default) gave best result.

Best Result = Subs in center, Phase =0.

Finally Waterfall graph to show the ringing in room. This one is particularly upsetting. The room definitely shows that the room needs major acoustic treatment.

What do you guys think?
