I was just recently in another thread that brought up a neat tip from Robert Harley's book, "The Complete Guide to High End Audio" about setting the phase of one's subwoofer to best match the loudspeakers' phase in the room that you have. Before all components discussed in this book, he first addresses various means by which one can obtain the best sound from one's room. Loudspeaker placement (i.e. proximity to walls, toe-in, etc.), listening position, common room problems and how to fix them with absorption panels are just a few of the items mentioned in this chapter. I would like to hear the experiences of people that have spent the hours of time "getting the best sound from your room". Basically what you have done, and how did it affect your listening experience?
