Can you guys direct me to some threads that explain the basic (I am very much a noob) like:
- Speaker placement inside the wall - how far apart does each speaker have to be?? How high?
- Where to place the sub?
- Placement of the screen on the wall - how far should it be from ceiling and floor?
- What type of sound proofing is needed behind the false wall?
Sorry for all the questions but I am very new to this. Being a complete noob I know it doesn't have to be perfect because I am too ignorant to know the difference on most things.....but I would like to try and get it right
I am hoping to sit 12' away and use a 90" screen if possible. I know the dimensions of the screen are 44.5h x 78.3w. Does this mean I can just frame out the area behind the screen to hold all speakers and place then mount the screen to cover everything? Once the screen is mounted can I drywall up to the edge of the screen?
Sorry for all the questions but I really do appreciate your time
1) Speakers will be placed based upon where your framing is, and then how wide your screen is, and whether or not it is acoustically transparent (AT). Height should have tweeters at seated ear height. Will create a better soundstage if you use all the same speakers for LCR. (That will likely mean AT screen).
2) Again, based on where it sounds best. A lot of folks put them between the center and L/R if you want them behind the false wall.
3) Sit in the area and get a sense of where your sight lines are. I typically have slightly more space at the bottom than the top, but again, that will depend on your ceiling height. Project the image on the wall to start and get it to the same size of your screen. Move it up and down. Sit it your chair. Where does it look good to you, and not produce eye strain? Mark the bottom of the image with painters tape and then get out the tape measure and a pad and pencil. Work the numbers to determine how to build your false wall and screen support. Keep in mind the sight lines if you have a riser in the back.
4) 1"-2" Owens Corning QuietR or Linacoustic.
FYI ... 90" at 12' is going to look small. I suggest you throw the image on the wall and make it bigger and smaller while you are determining height of image. Go with what you like, but IMO, 90" @12' is not going to do it for you.
