Thebestthereis,

 

here's the same text but modified a bit for easier understanding:

 

 

if you try it like this, you should get good results:

Make all measurements at the MLP with the mike vertical (pointing to the ceiling).
you should set the sensitivity on each sub separately, to about 70-72 dB SPL.

then check the overall level with both subs working; the resultant SPL should be higher than for one sub alone.

then, with the meter at the MLP and with the avr playing the sub pink noise, adjust the phase on one of the subs in order to get maximum SPL.



now, run Audyssey and make only one measurement, at the MLP and then "calculate".
next, check in the AVR for the channel levels. as long as the reading for the sub is not maxed out on either the plus or minus side, it should be ok (i prefer a bit on the minus side, like -3/-5dB). if not, then make new sensitivity adjustments on the subs, always keeping them at similar levels, and run Audyssey again.



when the subs are well matched to the other speakers for level, then run Audyssey in a normal fashion, using all the available mic positions.

when done, if you want a flat-to-the-ear response, increase sub level in the AVR by 3 dB; don't touch the sensitivity settings on the subs...

 

when you're done, please give your comments on the results after doing some listening.

I decided to leave it close to the wall like most recommend; although, I wonder if it is too close. Here are some pics of the current position:





I'd raise that bad boy up off the ground a good 4" to 6" ... and try moving it away from the wall a little bit :-)  FWIW
