I am setting up a multi-room set-up in the Master Bath of our new house.  I am going to have one in-ceiling speaker in the wet room.  This speaker needs to be weather resistant and have stereo inputs. The best speaker I have found for this application is the Monitor Audio AWC265-T2.  It is an 8 Ohm speaker with two tweeters to provide both left and right sound. The wet room is about 6 feet by 9 feet with a sloped ceiling and a lot of glass (two big windows and a wall of glass).  The other part of the set-up is the part of the bathroom with the sinks and is 6 feet by 11 feet.  I want to use 2 Sonance in-wall speakers in that room.  They would be set 8 feet off the ground, 2 feet from the ceiling on the short wall which is only 6 feet wide.  A couple of questions.  Are the tweeters pivoting in the Sonance in-wall speakers?  Can I use remote volume switches between the amp, that will be the source for all 4 speakers (Amp will see the Monitor Audio speaker as 2) and the speakers so that I can vary the volume in the 2 rooms independently? Can I use Trueplay in this situation if I turn off the Monitor Audio speaker while I am doing it?  Will the Sonance in-wall speakers work in the bathroom? Yes the humidity will be higher, but it is a big room with two continuously operating exhaust fans (HRV).
