I've been experimenting with ARC while reading through the forum. I know that as my sub is in the corner of the lounge there is some reflection gain from the corner. I dont really have another option in terms of moving the sub, well one that would keen my marriage on an even keel
particularly after recently shipping the ascends to NZ and buying the anthem
My readings are as follows:
Dolby Vol Calibration offset -3
Front Left +3
Front Right +3
Surround Right -1
Surround Left -3
Sub Woofer -10
I've attached the graphs and targets. I know looking at the readings that the sub volume is too high. I did turn right down on a previous run and it took the sub level down to -6.
It would be really awesome to hear your expert opinions on anything else I can do to blend the sub.
The other issue I have is that I listen to a massive range of genres. Everything from indie, rock to drum and bass and dubstep. I find the arc settings great for indie, rock and the bass is well integrated but where dubstep has the bassline as the main event I keep wanting to alter the bass higher. Do any of you guys have similar issues between genres or should I just do what everyone says and listen to arc untouched for a few weeks.

I imagine this will not reach you till tomorrow... unless you are a worse night owl than me! But here are a few thoughts based on what I'm seeing..
1) Your sub is, as you observed, up way to high. What is interesting is your first run was at -6 (which is still to high) and you turned it up for the next run? If your sub was at -6 at 9 o'clock and is at -10 at 12 o'clock, I think I would try around 7 o'clock. We would love to see it between -3 to +3.
2) Your sub is suffering from boundary gain. You can see its stron influance from about 30-50Hz. This is not helping, but if you have no ability to re-locate, probably not much you can do. You can try rotating the sub and seeing if it improves. Try turning the sub at 45, 90, 180 and angles in between. You may find one that works better than what you have now.
3) Your cutoff on the sub is currently set at 100. This is not bad, though we aim for 120 naturally
. Are all of the lowpass filters disabled/bypassed? Or at least set as high as they will go, probably something like 180Hz?
4) Your main speakers look good, though there is an odd dip from 100-200Hz. Not sure what is causing that and likely not much you can do about it. However ARC has nicely corrected for it. Currently to fill that dip is using about 6db of fill, which is the most that ARC will apply and as the dip is in the main range where typically room gain has a large influance, I don't think you would want to try adjusting your room gain up from where ARC set it as you won't be able to fill anymore to match a higher room gain. However, the current room gain is good and I don't think you would want to raise it. Just be aware that it is also probably not an option, even if you did feel you wanted to raise it at some point.
5) Center looks awesome.
6) Surrounds look good.
On the whole, things look really good. How does it sound? If I were to invest any time playing, I would see what could be done with the sub.
Then, I would listen for a solid week and see how things are sounding, as you suggested. If you have one particular track/album/genres of music that you feel needs a little help (more bass, less treble, etc). I would consider that more a recording issue of that particular album or genres. After all, if it sounds correct for other genres, than the amp and speakers are working as they are meant to (they don't know what genres of music you are listening to... they treat them all the same
). However, you can make on the fly adjusments of the bass and treble controls to suit your taste for an album that needs some assistance. Keep in mind that the music recording industry does not set standards the way the movie industry does... so it is a very real possiblity that different genres of music and music mixed at different studios by different techs will sound very different.
To use the on the fly bass and treble controls, use the 'Audio' button on your remote, press it a couple of times till the front display of the MRX shows Bass (and with one more press Treble). Then use the up down arrows to adjust up and down to your preference. NOTE: these adjustments will be lost as soon as you turn off the MRX or switch sources, they are temporary. If you wanted to set them permanently on a particular source, you can do that under the source setup of the MRX setup menu. Though, as it is only one particular genres of music you are looking to affect, I think the on the fly adjustment, when needed to suit your taste, is the way to go.
Again, before you start playing with the Bass and Treble controls... I would listen for at least 1 week first... just to set a good mental base line
