PB, if the auto-calibration set the receiver sub trim at -15, that indicates that the 11:00 setting on the sub volume controls is too high and should be reduced so that the result after calibration is closer to 0.

Thanks JohnK & sirquack. When I ran audyssey with one sub at a time my sub trim was set to +2. When I run it with both subs on it sets it -10 to -15 depending on setting on subs. I can tweak to my personal preference on AVR, but I am still wondering how this affects the trim levels of the other speakers? I going out grab a meter tonight, where can I get a test CD? Does radio shack sell those as well? BB?

I guess I should have added that when my subs are set to 10 or 11:00 & the avr sets trim to -10, When I turn up avr to -2 to 0 it sounds great.

If you run the sub "hotter" than the auto-calibration set it, either by increasing the volume control on the sub or the sub trim control, the other trim levels aren't affected. While some prefer to set the sub a few dBs "hot", the 8-10dB you mention seems a bit high. Keep in mind that a sub isn't supposed to call attention to itself as a separate sonic entity; the impression should be that the sub isn't working but the speakers are putting out more bass.

Pit, I did not use Audyssey to setup my subs initially, prior to running Audyssey. I used a Radio Shack SPL meter from the primary seat at ear level. I used the receivers manual built in test tone (pink noise), leaving the receiver sub level at 0dB to start. Then calibrated each sub one by one to the speakers, then turned them both on. The combined subs all on will have a higher SPL dB reading, but I have found that worked best for me. Some recommend to set them each about 3dB lower than the speakers, then when combined it will bring them up to match the speakers. You will just have to experiment, and may have to retry a few times till it works out. For my setup with an Axiom EP600, I have to have my receiver at -5dB, otherwise my EP600 volume would have to be to low to compensate.

Run Audyssey last. Also, one trick that many don't know. After Audyssey's first sweep, you can calculate and check the settings, without running all 8 locations, just to see what it does to the sub. Once your happy with the results, rerun for all locations.

Thanks for the tip and you're right I think many do not know that. \:\)

yeah it saves a lot of time. it is nice whey your trying to get the distances right as well. Since my 600 always comes in at 27ft and my 350's are correct distances. I usually try to get them as close to the same as possible, since there is only one distance setting for the speakers.

Thanks for the advice sirquack. I think my main issue is I've been calibrating both subs together. After reading everyone's suggestions I realize it would be beneficial to calibrate one at a time. You suggest running Audyssey last, but if both subs are dialed in won't Audyssey still trim them down? I gather the goal is to get them set at a point where Audyssey doesn't need to trim down? But if I prefer them to run a little "hot" the key is calibrate one, run Audyssey, then turn the second sub on matching level of 1st??? That will add the "hotness"? Make sense?
