About an hour ago I plugged in my dual core and ran the calibration - i'm still a little queasy...
I'll get to it in a bit
Very easy setup; single rca cable from my Onkyo receiver to the dual core and from it, two rca cables to my two SVS SB13-plus subwoofers. Language selection->calibration, select 2 subs mono mode brings you to the level adjustment screen. With the dual core calibration volume/level set to max, the "level ok" label flickered on and off so I raised the volume on the subs 6 db and as expected I got "level ok" at a bit lower level. So, I hit the ok button
What happens next is a little foggy but i'm sure I sat on the floor next to a subwoofer amazed at the staggering pressure the subs did to my room! When the calibration started to cycle left and right sub very smoothly I felt motion sickness kick in. No, i'm totally serious and as far as I know not at all "sensitive" to bass or high volume. This was just way more intense than the cinema ever have been in my experience. Since I've never been even close to that kind of output from my subs before, it's good to know what they really are capable of.
Anyway, I think a bit of a waring to people living in apartments is in order; it's loud and in my case lasted somewhere around 5 min, possibly 6-7 min.
Oh, calibration is a series of slow going low to high freq. sweeps - I think I counted 6 sweeps in all, aprox 1 min each.
I haven't really listened to the system after setup - I just ran a quick 3 point audyssey calibration with the Onkyo and reset the crossover from 40 to 80 Hz on my front and center speaker. As soon as my head and ears clear up a bit i'll have a proper listening session.
I attached a picture of the calibration results, you should see it below if all went well.
Oh, yeah.. the missus ran out of the apartment during the fist sweep giving me the evil eye as she went. When she came back she told me i'm crazy and that she expects at least a few complaints coming in to our landlord With luck it's possible to export the calibration file and re-load it should a firmware upgrade, lightning or other reset the unit, and require a new calibration. I really don't want to do it again in a apartment.
I just wanted to mention I will re-calibrate at a lower volume setting during this summer. I think the curve will look a lot smoother If I can tune in a volume level just below the point where everything in my apartment shake 'n rattle like crazy.
Some time and energy to determine a better location for one or both subs would be great (~60Hz dip). Also, I'll do the calibration in 0-120Hz range rather than full range (I found the range selection in the calibration\advanced menu). I'm planning to upgrade my onk 5007 receiver to a 2012 model as well (looking forward to have a go at XT32!).
