With the sofa (main seating location) up against the back wall, where do I place the microphone to get the 7th and 8th position measurements?
Use it to 'fill in' around the MLP positions. General info on mic placement here, in the FAQ:

d)3. Where should I position the mic for best results?

I found this in an article which featured an interview with Chris Kyriakakis, Audyssey's CTO and founder:

"The mic should always be placed at a seated listener's ear height and facing the ceiling; it's calibrated to work best that way. The ideal way to position the mic is to place it on a camera tripod. Start in the center position and then move 2 feet to the left of it and then 2 feet to the right. Continuing through the next mic positions move 2 feet forward and take three more measurements in parallel with the first three. If you have Audyssey MultEQ XT, take the seventh and eighth measurements about 1 foot to either side of the center point and slightly forward of it (or behind it, if the couch is not up against the wall)."

FAQ UPDATE!!

I have added a new section to the FAQ, called Audyssey and Dolby Atmos.

This section currently has just three questions with provisional answers. As more information about Audyssey and Atmos comes out over the next few weeks I will update and add to this section.

k1) How do I place the mic for Dolby Atmos ceiling speakers?

k)2. Will Audyssey work properly with Atmos-enabled speaker designs?

k)3. Will a calibration include the added speakers in the Atmos configuration?

As you can see from the links, he isn't likely to agree with your opinion.

But I am not debating it with you, so there's no need to reply.
Thank you for sharing these articles. Actually neither one of them addresses the original topic, i.e. designing speakers to interact with room modes. The authors are making measurements in their own rooms with their particular room dimensions.

For a speaker/driver design engineer at Klipsch, KEF, Boston Acoustics, Dali, Jamo, etc. it would be mission impossible to achive such a goal. Let's think of it this way. It would really be wonderful to have speakers that take into consideration our own room's modes coz in that case there would be no need for acoustical treatments and electronic EQ since the speaker/driver designed in such a way and placed into our rooms (read: any room) would immediately identify the particular room modes and would take care of them instantly. Great idea, but unfortunately that is not the case. Our common sense dictates the other way around.

Or a beast said: "I think something has gotten lost in translation here...Room modes are inherent to listening to speakers in any enclosed space, and designers know that, but they certainly don't design around that..."

Thank you again for trying to help.

Thank you for trying to understand the articles.

You probably need to read them again, perhaps more thoroughly.

Me thinks you need to try to read what beast and I have said again. Beast has more subs in his room than you and I together!
