This sort of difficulty is a reason one might prefer Pioneer's MCACC to Audyssey. The MCACC auto calibration sets crossover, volume, distance, and equalization values which you have direct access to and can later adjust as you see fit.

Hey Greg

Yeah, Audyssey Calibration sets the same values and does allow you to adjust your settings afterwards. Part of my initial post included that I had manually adjusted the Crossover to 120Hz and was curious as to the impacts that would have on my sound.

Anyway... Frequency sweeps coming today!

Well I just ran a Frequency Analyzer and test tones from 100hz to 200hz. Nothing wrong with the speaker at all. Granted it differs from the readings off my M22s but the response is, indeed, near flat down to 100hz. Same thing with Pink Noise tests.

My only conlusion is that Audyssey is
So... now to manually calibrate my system. Argh. Does this mean I'll lose Dynamic Volume?

Do you have the latest Denon Firmware?

Nevermind I see you have the 1900 series, IIRC it is not updateable, at least not without a trip to a Denon service center.

UPDATE: My seating area is so small that, until this point I was only calibrating for 1 seating position... mine. Re-Ran Audyssey for 4 locations and it came up MUCH better:

Speakers:
Front: M22
Centre: M100
Surround: QS8

1 Location X-Over settings:
Front: 40hz
Centre: 200hz
Surround: 110hz

4 Location X-Over settings
Front: 60hz
Centre: 80hz
Surround: 90hz

That is the thing with Audyssey, you have to use at lest 4 locations for it to work properly; sorry we never mentioned it before.

Snazzed, have you seen this article on Audyssey calibration? Part V gives a detailed step-by-step (with a diagram) method for proper microphone placement.

Hey Wheelz

No, I hadn't seen that, it would have been very helpful. Funny, when looking at the diagram for 8 mic placements when measuring a single location, locations 1-4 are exactly what I did. Now... do I do it again with all 8?

Perhaps if I'm board one day.

Thanks all

My room is pretty small too. I have space for four people. When I have actually ran Aud and used all 8 spots, the results were much, much better. It seamed ridiculous to me to move the damn mic two feet to left, then two feet to the right, then a couple feet back, etc....but in the end, the results were worth the agony of the set up. It takes a good thirty minutes to do it right. I just grab a beer, the remote and find a comfortable spot of the floor out of the way and remain silent. Also make sure you do the set up when there is no one else around to make noise.

I had this same results as Michael when I calibrated for all eight spots.

My mom and I measured and marked each location with a piece of tape on the floor, then I placed the microphone (I taped it to the top of my father's camera tripod which was adjusted to ear level (when sitting)) in each spot and calibrated.

It was over a year ago that I ran Audyssey, but if memory serves me correctly, I'm pretty sure it's highly recommended to use a tripod or something of the sort to hold the microphone, rather than sitting in on a chesterfield or holding it in your hand, because objects nearby (especially a wall) will cause reflections that will result in an improper calibration.
