I've been thinking about Mic patterns and I'm still not sure what to do for the best. I think I'll just have to pick a pattern, live with it for a week, then start experimenting.
That's what I did/am doing. My last cal was very heavily biased to MLP and was excellent - the best I have ever heard it sound here.
I really need to get myself another Mic and start measuring with REW to see what is going on, but I could do without the extra cost at the moment.
My OmniMic paid for itself in terms of SQ by helping me first identify my big dip in the bass near the XO region, and then helping me eliminate it. My bass has never sounded so tight, deep and overall good. Without the OM I would have had to rely on Pro 100% and, while very good, that would not have been as good as I got it in the end by using the sub distance adjustment tweak.EDIT:
Finished a 12 point calibration around the MLP only. Superb sound. Too soon to say if it is any better than the last one (heavily biased to MLP). I have yet to do any sub distance tweaks - that is the next job.2nd EDIT
: Interesting. Audyssey set my sub distances to 12.2 and 12.0. This is *exactly* what I adjusted them to in the last calibration - they had been 12.8 and 11.2 and after OmniMic tweaking, they ended up at 12.2 and 12.0, which is where Audyssey itself set them today. The interesting thing is that after my OM session this afternoon, I cannot improve on the 12.2 and 12.0 that Audyssey set. Subjectively, the bass is the same as it was before. It graphs slightly differently in OM but it must be insufficient difference to be audible.
Differences between the two calibrations are 1) the mic positions were all centred around the MLP this time and 2) I have toed in the L and R speakers more, so they are now pointing exactly at the MLP, and the centre speaker is pointing much more directly at my head when seated at the MLP. The reason for messing with the toe-ins was that I believe I was getting a very slight 'edginess' on dialogue more often than not, and I decided to experiment with toe-in adjustments to see if I could, by more precise tweeter aiming, get Audyssey to do a little less work. This seems to have been successful as listening tests made later show no sign of the slight edginess on any material.
WRT to the mic pattern, I don't think concentrating around the MLP has made a huge difference - my last cal used a pattern predominately around the MLP and far less so around 2ndMLP. Of course, I have made the mic pattern change and the toe-in change at the same time so it is difficult to be sure which has had most influence on the result. I considered doing these two changes separately but in the end decided that that would take an entire day and I couldn't muster up the motivation.
I am extremely happy with the latest cal - as I was with the last one, other than this slight edginess on dialogue. I say 'slight' and I mean it - at times I think I may have been convincing myself. However, I now believe it is gone entirely, so placebo or not, it's a result. As a by-product, I also think that the extended treble is somewhat smoother - I attribute this to the precise toe-in of the speakers.
As usual, I will leave this cal alone for a week or so while I get used to it and play a variety of material. But happy bunny mode is definitely ON
