Hello, I am finishing my basement with a front wall 20' wide with log cabin siding. The depth of the room is 14' (that will be tongue and groove pine)with a bulkhead starting at 10' that drops the height of the room down from 8' to 7'. So there is 4' of lowered ceiling in the surround area. Behind the bulkhead will open into a games room with kitchenette. I was wanting to go with all ceiling speakers (recessed) but now understand that is not a wise choice. I do not want to mount front speakers on the cabin siding. To save money I was thinking about mounting my Bose am5 to the ceiling, with my Bose center channel under the tv(not mounted ). For surround I cannot use my Bose star derived surrounds due to headroom so I thought about the Polk rc60 for $119 /pr on amazon. Later I could upgrade the front speakers because I understand Bose is not the best. Any thoughts on this approach?Thanks Don
