I just finished rerunning Audyssey and noticed that it set my sub distance to 27ft when it should really be around 9/10 ft. The distances for all other speakers are correct. The SPL level set for the sub also seems correct. Is this normal? Should I manually change the distance to what it really is? Thanks.

IIRC, the DSP causes this anomaly. I would try it set up with the correct distance and with it as the program found and go with the distance you find gives the best sound.

Thanks Jason, I'll give that a try and see if I can hear a difference. The thing with Audyssey is that it doesn't matter how many times I run it, I always get different results even though I always run it at night when everybody is asleep and the house is quite and I always try to measure the same way. This time I wrote down the dB levels that I had and comparing to this new run, some levels are off by 0.5, some by 1 and my sub is even set 1.5dB lower this time. It's very strange as nothing has changed this I ran it a few months ago

sometimes one has to be very careful about seemingly small details. one time i ran Audyssey and my bass was too weak (sub) and the distance was much longer than it should have been; then i remembered that there is a rr track about half a mile from my house and in between 2 mic positions i had heard a barely perceptible "tick-tick" somewhere". it was a train that had gone by and had made something move in the house. there surely was some infra sounds coming in the house too, but i could not hear it nor feel it. also, the sub was behind the FL M80 and hidden from view. that was enough to skew the sub's calibration.
what i would do is make sure that things are all in their definitive place in your av room, with no speaker hidden from the LP, and make calibr. as often as necessary until you get the right one.
what i found is that if the sub's sound output is hidden from the microphone for the first measurement (at listening position), the distance will not be right (along with other things), and it might be a sign for you to rearrange some furniture in order to get a better calibration.
hope this helps. :-)

Thanks JB. In a suburban area it's not easy to avoid every noise, even at midnight. Heck, even my LCD makes more noise than I would like and is easily audible When I'll get a chance I'll try to rerun Audyssey and see what I get. Since I first got my system I've run Audyssey probably a dozen time and I have to admit that up to now, I've never been fond of the results that I got from it, I use it mostly to setup channel levels and distances and for the Dynamic Volume feature that I find very useful when watching TV at night when everyone is asleep.

Yeah, I have this document and followed it as best as I could. Thanks.

Even if your mic positions are not in the "exact" place each time you will get slightly different results. Or, if you are standing in the room in front of one of the measuring speakers, that will affect the results. Even a high back reclining chair, table, or other piece of furniture between the mic and speaker can cause reflections altering your results.

In regards to your sub measurements, that is normal for a DSP sub, and should be left alone. It has been covered on many audyssey related forums over on AVS. My EP350's (non dsp) measure exactly the right distance, but my EP600 has always added 10-15ft to the physical measurement.

I still think that someone will someday come up with a dual mic setup that can be positioned to represent the left and right ears independently. Sure, it will need to be able to have different distances between left and right to represent different sized heads, but I mean, come on, who has one ear on the front of their forehead.
