Harbeth Compact 7-ES2 owners: placement question

Due to room configuration, I position speakers a maximium of one foot off a bookshelf. My seating position is 9' from the speakers with a window/wall directly behind my couch. Side walls are 5 1/2' on one side and 9' on the other (off current speakers) Does this scenario present any problems for this speaker?
