I posted this on the Official Audyssey thread and thought I would post it here too.
FYI, I placed the mic on the top of my couch for two positions and on a tripod for the other four.
I just recalibrated my room (I have an Onkyo TX-SR706 AVR.) using the procedures contained in this thread and am very pleased with the results. I had previously calibrated the room following the instructions in the owner's manual and was happy but the bass didn't sound quite right.
My sub does not have an LFE input so I set the crossover (on the sub) to 120 hz (Max is 180 but I had previously found that setting to sound rather bloated and boomy in previous calibrations.) with the sub amp gain set at 1/2.
On the speaker setup menu of the Onkyo I set all the speakers to "Full" and the sub crossover to 120 hz.
After running 6 points around my listening position the speaker distances came back within a few inches of what I measure with a tape measure. The -3 db points were as follows:
Front, 40 hz
Center, 60 hz
Surround, 90 hz
I set all 5 speakers and the LFE crossover to 80 hz (Yeah, I know you are not supposed to LOWER the crossover from the measured -3 db points, but what's 10 hz among friends. Besides, 80 hz is easier to remember.).
Gain values came back as:
Front, -6 db
Right Surround, -7 bd
Left Surround, -8 db (I have a slight echo on the left that Audyssey apparently can hear better than I can.)
Sub, -4.5 db
I prefer my surrounds slightly louder (Def Tech BP2X bipoles that are actually mounted behind me due to the room configuration.), so I set the gain on them to -4 db. I also bumped the sub up to -3 db.
My reference for music bass is the Holly Cole CD, "Don't Smoke In Bed." It has a great double bass that can sound very boomy if not set up right. With the Audyssey settings the bass is very tight and deep. It sounds like it is in the room with you. Very impressive.
For movie bass and low-freq effects, the footsteps of Ironman as he is stomping through the cave are downright frightening!
Surround settings usually take a few movies to get right so I will be tweaking those for a little bit.
All in all, I must say that I am very impressed.
