Do these still pretty much hold true (for a starting point)

A lot of very useful information about speaker layout and room acoustics can be found at the Dolby website:

Hope this helps.

Hi DetroitIrish...
What exactly is it you're trying to setup? 4 speakers for home theater?

Pretty much ya, its for a 5.1 (7.1 will be later on down the road & in different room)
The pics are supposed to show optimal layout for fronts & rears (pretty ovious where the C goes )

PS I checked out
http://www.dolby.com/consumer/home_entertainment/roomlayout2.html before i poested, I didnt feel like doing all the math got get the angles right, figured this was a simplfied version of the same thing ;)
The room its going in now is 24' wide and 15 'deep, which backs up to the kitchen (no walls) which is another 16 'deep and 16' vaulted ceilings... If that helps
Heres some pix (before we moved in) to give you an idea. I'd take more recent ones but that envolves work LOL

Its not the typical "4 walls to a room" , pretty much open concept , HOPEFULLY next year everything gets moved to the basement, with a projector, and the current FR, is going to be an entertainment room (ie ppol table/music, some seating etc..)

I think you would want to follow the Dolby recommendations as closely as possible. That will be based upon the seating position which you don't show. Anything else is a compromise.

Yeah, that Dolby site is a good place to start.
There's always some play, or disagreement about what's best. For 5.1 configurations, a lot of people like placing the surround speakers further to the back, say at a 135 angle or so...sort of opposite the fron L/R speakers. This can provide a more 360 immersive feeling, but not everyone agrees. For multichannel audio it's the standard. For movies, having the surrounds approximately on either side of your head is probably still the more popular configuration. Personally, I prefered moving the speakers back to 110 and even 135 when I had a 5.1 setup.


Here's THX's site:

You'll notice for 7.1 (I know you're only 5.1 for now) that they link to Dolby's recommended rear speaker positioning, which is different from theirs. That just shows you that you might need some trial and error to see what's best for you.

I used to have a room bigger than yours, but we built a new home this year and I finally got to make a dedicated HT room, 20 long by 16 wide. My setup is a 7.1 config, in between Dolby and THX's suggestions.

Another vote for Dolby. You could also try DVE or other HT set up/calibration disc. They are available for rent if you already have Netflix.

That will be based upon the seating position which you don't show. .

For now, yes.
If we watch a movie together there, she usually lays on the couch, but thats pretty much where i go to realx, and kill people (on SOCOM)

She's more interested in how everything looks as opposed to how it sounds... You shoulve seen her ent center b4 i met her...LOL

Hi, DI and welcome! My arrangement is similar to yours including the use of Polk speakers. As for your center, I have a suggestion: move it up one shelf and turn it over. Since most of the voice track in a multi-channel system is mixed to the center, it is important for articulation that the speaker be easily heard. It appears to be firing at the ottoman now.

Polk intentionally put an angle on one side of their centers for it to aim upwards to accomodate system arrangements like ours. You may want to give it a try. FWIW, there are some pics of the HT system in my gallery.

E Stat, thanks for the tip! Unfortunately, it wont go up a shlf though, fixed shelves, and the top one is not big enough for the C. I will try to flip it though!
