You know Dave, I have used my Bose L1 Compact in all of it's possible configurations and for the life of me, I just don't hear enough difference to worry about it. The only times I think it does make a difference is in a large room - where the full extensions are needed for full room coverage. I know what Bose has to say about the science of it but I just have not had a problem with any of the configurations I have used in the rooms I play. As for standing. I stand only in cases where I have to move to another room in the same building for double gigs where I use the setup shown in the videos. All other gigs I sit.
