Bass+surround placement in my new living room

Hi,
Attached is the sketch which approximates the structure of my new living room under construction. Wall D has a glass wall/big window. I would like to lay the sitting couch against wall B or C and the TV/front & center opposite it.

I need to set up a 5.1 here. Where would you folks suggest I place my fronts and center speakers? Should it be on Wall B or C?

Do keep in mind, that wall D has a glass pane, and wall B has an opening for a door.

Also, I have provided for an under the floor wiring channel from wall B to C, so that my surround speaker wires do not become a site for soar eyes. I could do this, because the need to setup a 5.1 system struck me before my flooring was done in the room :)

Oh and wall C is about 18 foot and wall A is about 11 foot.

It should be either wall A or D. That puts the wall behind you farther back, which gives a much flatter low frequency response. The drawing below shows the ideal 5.1 setup in a rectangular room, and the response graph below that shows the large improvement you get when the speakers fire the longer way down the room. It is possible to get a decent low end with a room oriented the short/wide way, but that requires a lot more bass trapping. Also, surround speakers are supposed to be well behind you. So that's another reason to use the longer orientation.

Ethan Winer, thanks for pointing me in the right direction, but it turns out that its not a perfect world, and my family wants to put a small dining table in the room too. Also, wall A also has a small door now!

I have add more props to my design, showing one way how I can use the room for my setup. Any suggestions on this approach? Will the dining area be of much concern to the acoustics?

From the looks of things, there is no other choice for you than what you just posted. No other placement options. So, do the best with that location.

hehe, I just did a quick draw to give u ppl an idea. So, the table size is not to scale, and just an approximation :)

I use Visio, but that's probably overkill for simple drawings. There's a free program called Sketch-up you can get from Google. I don't use it so I don't have the details about where to download it. I'm sure a Google search will take you right there.

I agree

You want the main speakers and your sitting area to be a triangle. The distance between the main speakers should be the same distance from your couch. If the main speakers are 10 feet apart. Then your couch should be 10 feet from them. Keep your surrounds as high up as possible. The center of your center speaker should be within 12" of the center of your mains. :D
