Hmm, Im going to check some things out. The room is about 18' by 12' but it does open up to the dining room. The M22s are toed intowards the left and righ positions on the couch, not all the way towards center position. They are about 18" off the back wall and around 2' on either side of the TV. They are on FMS16 stands so the tweet is close to ear level, and the woofers(is that what they are called) have no obstructions as the are higher than the coffee table. I did place the mic on top of the sofa, but with my old speakers, the audyssey set the crossover at full band. Would have the polarity mixed up do this, I did just recently do a in wall speaker wire set up, and I will check that tongiht and redo the audessey.
