Help me place my speakers!

I got my surround sound system right before we put up our xmas tree. So, for the past month, my speakers have sort of been in a temporary location. Now that the tree is down, I'm looking to find a permanent, ideal location for them.

I've attached a very precise, almost professional diagram to show you the layout of my room . As you can see, because of the angle of the TV and the couch, there is no real obvious place to put the 2 rear speakers.

If I put them in corners B and C (which was my instinct), the couch would be much closer to B than C.

Now I'm thinking that they should go in corners A and C. My only concern there is that they would be a little bit in front of the viewer, and I always thought that they should be behind or next to the viewer.

One other thing--the center speaker and the right and left speaker are aligned with the TV. When I saved the file as a JPEG, the angles got all out of whack. I'm not sure why. Just ignore it.

Thanks, LordGAD.

The only problem I could see with that is that I would have to move the couch to the center of the room.

Or, I guess I could tuck them between the couch and the chairs (on each side), up against the wall.

How do you think that would work?

That should work fine. You could also think about putting the overhead in the ceiling. People get all up tight about the placement of surround speakers and often unnecessarily so. The first thing to do is to realize that these are surround speakers, not REAR SPEAKERS. This drives speaker manufacturers nuts. At seminars the instructors will jump all over you if you refer to surround speakers as REAR SPEAKERS! They will interrupt and reinforce they are SURROUND SPEAKERS and not REAR SPEAKERS.

Why? Because the sonic information that comes out of them are surround effects not directional rear sounds. Rear speakers harken back to the CD4 days where there was four separate channels with directional and positional sounds intended to come out of each corner of the room. What CD4 told us was people can not relate to directional sonic information and watch a screen, so surround information is best when it is non directional as far as the action on the screen goes.

Examples would be the crowd noise at a sporting event, random outdoor noise or birds chirping, wind noise, thunder and so on where the exact position is not important as long as you are enveloped in the scene with the directional sounds being concentrated forward toward the screen.

Having said all of that, it does not matter if the surround speakers are perfectly positioned as it matters for the front speakers. You could also add surround speakers to cover the room seating areas, perhaps alternating left surround and right surround as you move through the seating areas. That would allow you to have speakers on the outside of the chairs as well as between the couch and chairs at each side of the couch.

If you check theaters, you will see they actually have several speakers on each side of the theater and quite often a couple in the rear of the theater. Movie makers will put surround information in their soundtracks with this layout in mind and that's why only occasionally you will find directional information in the surround channels. An airplane or helicopter comming from the rear overhead and then on screen is one of the few things I can recall. In these limited cases your surround channels may not be optimum, but exact placement is not paramount for most surround material.

Wow! Great informative reply, rbinck. Thanks a bunch (to you and everyone else).

I like the idea of mounting them on the wall. But, I think that I'll pick up some cheapish, yet good stands (any recommendations would be welcomed) and perfect my positioning before doing that.

I have to say, and I'm getting off topic here, surround sound has made a bigger difference than I ever imagined it would. I love it. I crave movies now.

In the past 2 months, I got my surround sound set up and an HDTV. I love them both. But if I could only keep one, I think that I'd keep the surround sound. It makes such a huge difference when watching movies.

(I mounted my surround speakers on the wall about 1.5 feet down from the ceiling,they are Infinity 6in 2waysand it works great.

T wrecks,

After taking a look at your setup as it stands and if the room dimensions are close... and if you can get the better half to agree...

Move the display to the wall without pass thru's and windows. You want a minimum of light interaction shining on the display and with your setup now, the windows are a problem for day viewing.

Corner apps, for sound have a tendancy to set you up for unwanted "nulls" or holes in your sound.

Again if the dimensions are close to accurate, placing your couch 2/3rds from the main speakers back in your room, with the surrounds on either side slightly above and behind ear level would be best.

This would allow for the mains to be slightly pointed towards your listening position and the sub to be placed in either corner with about a foot into the room.

Did not mean to rain on your parade and setup. If a total makeover is not in the cards, then follow the others advice as they are spot on if you cannot optimize your room for your theater.

Good viewing,

Doug k

Thanks for the advice, d6500k. But you must be married...my better half wouldn't go for it.

except my Infinity surround speakers are mounted on the wall.

Got a great set of Infinity speakers dirt cheap on ebay.

Have you got your sum aimed out or into the corner?

As rbnick explained in his usual thorough fashion, surrounds are NOT rear speakers. But they appear to do best slightly rear of the seating position vs. directly overhead/side.
Pivoting drivers, arrays with wide dispersion, or surface mounted speakers on omni-mounts should all work equally well.

I'm gona put a 6.1 system in a bedroom size 11x10. The TV is right in front of the bed and the speakers are mountable speakers. I have to put them on the front- and back-wall. Can't put the rear speaker on the sidewalls since on one side I have a big mirror and I can hardly mount something on the mirror...my question is how high and far I should put the speakers up to get an optimal sound-experience.

For the surrounds in the back, the height is not that crtical. They should be slightly behind the seating (or laying position :) and aimed down accordingly. That should work from any height.
Fronts do best aimed at you directly, but they can be aimed as the surrounds are, from up the wall, but better have the center channel close to the same height and aimed the same.
6.1, you will have another aimed behind you from up on the back wall.
