I am new to the forum and wanted to get some advice on setting up my living room/ HT. Last year I built my HTPC, which if you haven’t built one yet you need to get on board, but that is a separate story. This year I want to replace my free standing front L/R and Rear L/R speakers with in wall/in ceiling speakers. The main reasons I want to do this is, first I have young children that love to explore the speakers and speaker stands, and second now that I have removed both my media cabinets that were used for CDs and DVD’s I want to get some more space back with the speakers off the floor. The room itself is not a dedicated HT (as much as I would like it to be) So I am sacrificing a little bit of function for form here. I do still love to watch a good action moving and love having the big sound of a dedicated HT but that is limited. I am thinking about doing in wall speakers in the front, Keeping the Center under the TV for now, and putting the rear either in wall or in ceiling. The room is 15x15 and open to the kitchen and rest of the house, the main seating against the back wall. And the ceiling is 12’ high. The only reason I am thinking about putting the rears in the ceiling is because the seating is right against the wall. I was thinking if I could get something that is bidirectional It would help fill the room but I am not really sure that is a good idea. Thoughts and suggestions?
