The QS8's are about 1 foot from the brick fire place on the Right and about 1.5-2 feet from the kitchen entrance on the left (They are not perfectly symmetrical since I screwed them into wall studs- drywall anchors could probably used successfully though- especially with a QS4) I can't comment too much on the side chair because I am always sitting in the center seat of the main couch . Of course, I have sat there a few times and there is not an overwhelming sound coming straight down on you from the QS8 driver. The surround field is off because one surround is right behind you and the other is way off to the right. Also sitting right next to the left m80 but being so far from the right m80 is not optimum (and you are pretty off axis from the center channel too.)

Basically, the love seat is not really used for watching movies or playing games unless company is over and it is the only choice. It is usually just my wife and me sitting on the main couch. During normal cable TV viewing the love seat is fine as most cable TV shows don't require a lot of surround sound effects. I angled the love seat so that it doesn't block the path between the main couch and the left 80

If I'm going with a twenty foot spread between the QS4's, I wonder if alot would be gained from putting the QS4's on the side walls. Of course, that would involve convincing my wife to let me put a speaker on the fireplace wall - don't think that will happen...

I'd always origionally envisioned a back-wall mount positon only being about 10 feet apart becasue I thought you were supposed to try to match the spread of your fronts...

Heya Mr. Moholic,
I started to answer your question but remembered This excellent article on 5.1 and 7.1 layouts. It is a great article from resident audio expert Alan Loft and it has very well done diagrams showing the optimum layouts for both 5.1 and 7.1, direct radiating vs. di and quad-polar speakers, and even sub woofer locations. It also talks about how optimum is not always a possible reality so you do what you can with what you have.

I think it will answer a lot of your questions. It did for me a t the time.


With great power comes Awesome irresponsibility.

That is what you do when running rear channels for a 7.X system or at least limit the width to the same, they can still be set narrower as per per Dolby specs.

Ax, as Jay pointed out, that concept of being spread about as widely as the mains applies to back surround speakers in a 7.1 setup, spreading them about as much as they're behind the listeners, in analogous fashion to the spread of the mains.

Since the 5.1 surrounds are side surrounds, they can be spread almost as far as they would be if they were actually mounted on the side walls rather than the back wall.

Enjoy the music, not the equipment.

Is my setup much the same as what you are planning? Sounds pretty damned awesome to me.

yes luke, similiar. Can I ask why you choose to install on the rear wall? - it looks like you could have put the surrounds on the side walls.

Looks great.

There is no wall on the left side of the room, its open into the rest of the living area and kitchen.

I had a similar room setup as you and was really not very happy with the results. Putting your couch up against a wall is the biggest problem with this. This is because to get some envelopment from surround speakers you need to have at least a little bit of space behind you. The second problem with sitting against a wall is that the bass causes you problems there. I would suggest that you at least get your sofa two or three feet off of the wall so that you can get a sound-field behind you. Ideally you would want to turn the room so that your front speakers are firing into the longer dimension of the room. Now, I know that there are two big problems with you doing either of these things: 1. WAF 2. you already have your main speakers mounted in/on the walls. But, I just want you to know that your investment may not produce the results you want because of the way your room is setup.

Getting the room to look good (as far as how the furniture is laid out) and getting the speakers and seats in the right locations in the room is one of the toughest things to do in a non-dedicated room.

Yep, its all a compromise... in all, the results are better than i thought possible.

I could move the lounge out to the middle of the room when I'm doing some hard-core watching/listening... maybe.
