System will be running off an already purchased Denon 4311 and would like to get rid of Energy wall mounted speakers and replace with in wall/ceilling speakers. It is a 5.1 system with the possibility of adding second subwoofer. Love what I'm hearing about the Monoprice speakers.Room is 15' wide by 12' deep opening to the kitchen behind the 12'.
Question 1 - have the opportunity to mount speakers in wall above TV facing primary seating location about 8' off the ground.. Would this be better than mounting in ceilling facing down?
Question 2 - see a lot of guys using the same three speakers for L/C/R speakers. Would it be better to mount the center speaker below TV, on cabinet at 36" or above TV in wall?
Question 3 - Subwoofer. Is 8" subwoofer big enough for this room. Should I keep the 8" sub and add a second sub? Should I just replace 8" sub with one 12" sub?
Question 4 - Primary seating position is at the 12' foot mark. Would it be better to mount surrounds a few feet behind the couch or right above the couch?
Will appreciate any and all coments regarding speaker selection and placement.
1. In my opinion mounting on a wall is preferred to a ceiling, especially when using it in home theater/TV application where the sound should be localized to a source (the TV). For a small room, where you are sitting very close to the TV in ceiling wouldn't be bad, but if you could be far away it would be lousy in my opinion.
2. Above or below, doesn't really matter. I would mount it in the location that will be closest to the height of your ears when you will be watching your TV. With your TV in a great room that joins with a kitchen, would you be watching TV from the kitchen while you cook. If so above the TV may be beneficial. It really depends on the height of you ears when you are watching TV and the height your TV is mounted at.
3. Some 8" subs are better than many 12" subs. So it is hard to make a general rule that you should get a larger sub. I would stick with the 8" for now and see how it sounds. If you want more bass, then upgrade.
4. You should look at the Dolby Speaker Placement guide.

Surround speakers are designed to be to the side a little behind the seating position (90 to 110 degs). They should be more wide, than behind. I have in ceiling and they are at placed to the side about 95 degs.
