Read though portions of your FAQ, tremendous job. Little confused on the gain matching of subs.
Currently, I have not gained matched, though using a the pro level matching, the sub gain settings are nearly identical, and the completed pro cal has the sub trims within .5db of one another. The subs are identical Fathom f113, in approximately equal opposing placement in the left and right front portions of the room.
If I were to gain match, I'm not sure what I'm doing with the initial sound meter reading with the sub in the center of the room. I surmise I am leaving the prerpro trim at 0, and shooting for the approximate reading, give or take, of 90 db with the sub trim, user the assumption the reading will drop nearer to 75 db once in returned to its original location and using the audyssey level match? Couldn't one put the each sub in the center of the room one a t a time and use the level match readout in pro for each sub to accomplish similar result, then run the full calibration and don't touch the Pro level adjustments further regardless of the error message, presuming you are withing +- 3db?
And on that +/- 3db point, you mention:
When the calibration has completed, observe what trim level Audyssey sets in the AVR for the sub channels. Ideally, it should be in the -3dB to +3 dB range. If it is too far towards either limit, go back to step 5 and use either a lower or higher target gain level, depending on your final results.
Right now, I am at -8 and -8.5 on the trims after level matching each sub in position. Why is this not optimal? I thought as long as you were not at the max trim levels (which would potentially imply more trim might have been needed but the range was not there), one was fine...
