It doesn't sound *that* bad. But there is a quite pronounced decrease in
bass as I walk through the doorway. You listen to the music and you
think the neighbors will be banking on the wall any minute now, and then
you step just outside the door and it suddenly seems radpically less
loud. I don't know if it's because you're out of line-of-sight with the
speakers or the width of the doorway or what...
