Adding to jazzmammal and John Conley's points about placement of the system, trying out in small vs. large rooms, etc.

Rewind far up in the thread where I asked where you were auditioning this system. John's description of how to set up in the vicinity of the L1 is right on and how I've seen/heard these systems used successfully for a middle sized room (banquet hall seating a little less than what John described).

Jazzmammal's point about auditioning in the sound in the middle of the room is right on the money. If you don't have signal cables that will reach from the middle of the room (or more appropriately, the middle of the area where the listeners will be), then take a friend along that can at least plunk out Happy Birthday on the keyboard at your performance location, while you roam the room listening.

Put the L1 and bass module in a corner, if you can, roam and listen. Then pull it away from the corner and walls and listen again. You are going to hear a huge difference, most likely. Which one is right? Good question. Many times you are not going to have a choice as to where to set up the thing. If it is really bothersome to you, I would suggest running some in-ear monitors for your sound, and let the room be what it is to within reason.
