@ cycles 2.... The AGD website can be tricky to navigate. The X 3's are listed, but the X 1's are not. Here is a link to them. The X and O series are 2 completely different lines. The O's are a premium line below the M series of speakers.I believe the X3 and X1 will be in different rooms on the 6th floor in Florida. The M3's will be part of a reference system in a ground level room.
