I will definitely be running Audyssey again, because I'm assuming that I might have got undesirable results placing the microphone on my sofa with the wall directly behind it causing additional reflections which is stated not to do-"If the seat back is a few inches behind the microphone, this will cause additional reflections". I don't imagine this will cure my LFE problems, but making the other recommended subwoofer adjustments just might.
Maybe someone could post their results after rerunning Audyssey.
Thanks for the link!
