My main concern is the Music profile which was done just using L/R and no sub..
My speakers are Dynaudio Confidence C2's which have a fairly decent bottom end...
Maybe all the experts here could have a look at my graphs and offer me some advice..
I see a few things... starting with what Jayray pointed out. Your low end is off the charts (literally and figuratively). Is there anything unique about your speakers, like is there an internal amp for the woofers (if yes can you turn the volume level down)? If not, I have to imagine you have them trapped in a corner at the moment. Try pulling them away from the corner a couple of feet (both from the front wall and the side wall). Once we get the low end to settle down a bit (probably in the mid 80's), ARC will be able to deal with things a lot better and should naturally set your speakers at 60 for both Movie and Music.
Once ARC sets your fronts to around 60/80, naturally on its own
, you should then adjust the your the cutoff of your fronts on the Music profile (and only the music profile) to probably around 35 or 40. Once you get your new charts posted we can better tell you were to set it, but you can start with 40 and we will let you know if you should go up or down a little once we see the new graphs. [Don't forget, once you adjust the cutoff in the targets window, you need to hit the "calculate" button before you take screen shots of your graphs or upload the new results]
Your surrounds look good, on the whole.
Can you post up your Speaker Calibration Levels for us to look at? I'm guessing your sub was set with a large negative number... if that is the case we should adjust the volume level on your sub.
As for your sub, it is also in a corner or tight to a wall? Again, like the fronts, moving this away from the walls will likely help some. We need to position it so that the large spike you see drops down close the the flat area you see from about 70-190Hz. Once we get that spike under control, your sub will likely head up to 120Hz naturally
. You can use Quick Measure to help you move the sub and see how the graph looks in real time.
Once you get everything moved, post up again so we can see how things look. We may have a second round of suggestions as some of what we are seeing is pretty dramatic right now.
Last comment I would make, once you get things where they belong, the bass from the Music Profile will be much better (it is suffering from the 120 cutoff ARC has set at the moment), however, you have likely become accustomed to way
to much bass with your old system. At least assuming your old system used the same speakers and speaker locations. I would expect it will take you a week or two for you to adjust to the new bass levels. Though they will likely sound a lot more detailed with less thumping and mud then your old setup sounded, right out of the gate. (Unless, of course, your old system had a decent built in EQ that was helping to tame the bass for you).
