Update: Some 43" tv's do fit in the master. - but you must reposition the speakers. You could go above, but we are going to put them below in the area by the porthole.
FWIW the Sony Bravia 48 fits perfectly in the salon and we are going with either 28" or 32" in the master. 32" would require more repositioning of the Bose speakers.
There is a thread for the 550/580. I found pdf's for how to remove the TV's in post #9 here: http://www.clubsearay.com/index.php?threads/58-sedan-bridge-official-thread.90211/
