Hello everybody!

I’m finally going to be ordering the last of my equipment and setting up my home theater, but I don’t know where to place the speakers and furniture in my room. I’ve spent so many hours trying to figure out where to put the furniture that I get a headache every time I think about it. I need your help!

Here is a to-scale layout of my living room:

I’ll be posting the information regarding my furniture and speaker placement in separate posts so that it isn’t all one huge post.

I don’t think speaker placement is going to be that big of a deal, but I thought it would be interesting to hear some different opinions.

Equipment:
57” Toshiba 57HX81 RPTV
Harman Kardon AVR-525 A/V Receiver
1 x JBL S-CENTERII Speaker (CTR)
4 x JBL S-38II Bookshelf Speakers (LS, RS, RLS, and RRS)
2 x JBL S-312II Floor-standing Speakers (FL and FR)
SVS 20-39 PC-Plus Subwoofer (SUB)

This is what I have planned:
Tom, from SVS, suggested the placement of the subwoofer.

The S-38II’s would be hung on the wall using small DIY shelves tilted at an angle as to direct the sound towards key seating, but someone told me that they thought the rear speakers should be closer to the key seating. I think that would be kind of hard to do; I would have to hang them from the ceiling somehow. From what I’ve heard about the JBL S-38II’s, there are no mounting mechanisms on them at all.

What do you guys think? BTW, how high up the wall should the speakers be?

This is how I have it setup right now, but the furniture needs to somehow face the new position of the TV (shown in the speaker layout above):

As you can see, there are three recliners and two sofas. I want the recliners to have a good view of the TV, as well as at least one sofa…

…see how frustrating it is? :angry:

Feel free to mess with the above image and move stuff around—that’s what I’ve been doing. If you can’t post the image after you’ve changed it around because you have nowhere to host it, email it to me at [email protected].

BTW, the fireplace is actually directly under the mantel. The area that I have labeled “Fireplace” on the layout is just the tiling that surrounds the fireplace. Therefore, I could place furniture on it, but it would block off the fireplace and just look… funny.

The door / doorway / mantel placement is dreadful for Home Theater seating...

Do you own this house?

If you do then get rid of that fireplace. You live in Portland, Oregon right? Do you really need to stoke a fire in a place that rarely (if ever) sees below freezing temperatures? :D I'm sure it looks good, but if it's just for show then there are other ways to make a living room look nice, like for example a grand piano, some framed art, a reading nook, etc.

With that said, here is my suggestion (the rear sofa would be put on a riser so the people could have an unobstructed view of the TV) :




I moved your TV out of it's corner position because that position is terrible for 5.1 surround sound. Plus, with the TV angled in the corner there is no good way to get 1 sofa and 3 recliners in view of the TV without blocking your front door.

BTW, this is going to be a 7.1 setup, not 5.1. Look at my second post that talks about the speaker placement so that you know what I was referring to and where I want everything to be.

I posted that speaker & TV layout first so that you could help me figure out where to put the furniture after knowing where the speakers & TV would be located at.

[c]:confused: I thought you guys would me more willing to help me. :frowning:[/c]

Well, I guess I'll share with you three different possible layouts that I've come up with. I was hoping that someone could come up with some better ideas.

Proposed Portable Riser Dimensions:
5' long
8' wide
8" high?

Sorry I didn't read your first request completely :) Here is another concept to consider:

http://extranet.digitalspinner.com/h...uggestion2.png

You could build a portable riser for at least the closest sofa, and perhaps another for the rear that is somewhat larger. Other issues addressed are: the center recliner has a direct line of sight and the best viewing position. The other recliners are angled 30 degrees, giving a non-claustrophobia inducing view of the room from the front door. You could put a nice round coffee table to service the 3 recliners.

Derek,

My room dimensions are very close to what you have, but I don't have enough height to build a riser. Click on my signature below to see a diagram of my layout.

I favor your next to last layout. Contrary to what your friend suggested, I believe you need a minimum of 6 feet between the rear seating and your rear surround speakers for a 7.1 configuration.

In narrow rooms such as ours I think it would be helpful to use dipole side surrounds to avoid that "IN YOUR FACE" effect from being too close to a speaker. If you must go with direct radiating side surrounds I would mount them higher than I would with dipoles and aim them over your head, i.e., not directed at the listener.

For the rear surrounds I went with direct radiating and pointed them down toward the listeners since they are more than 6 feet from the nearest listener. In that way they don't over power the important sounds coming from the front array.

I think you'll find if you were to draw a scale profile of your room with sight lines that you will run into trouble with only an 8" riser. The reason is that the screen on a rear projection TV doesn't sit high enough to provide clear sight lines from the rear seating. I suspect that even with a 12" riser you will encounter some line of sight problems.

As a quick rough approximation take my profile drawing and draw sight lines to my HDTV. You'll see what I mean.

Good luck.

Larry

Nope. Dolby simply recommends the rear surrounds to be within 60-90 degrees of the listening position (30-45 degrees for left and right). This has more to do with how far they are apart from eachother, in relation to the listener,

Hi Sean,

I assume you are referring to Dolby's guidelines regarding their Surround EX standard which state:

Rear speaker placement is somewhat less critical. Here the main goal for both film and music is to produce a diffuse and enveloping soundfield. The height of rear speakers will depend on both room size and furnishing.In general, placement of the rear speaker(s) above the listening area can be very effective. Note, however, that placing these speakers too high in a narrow room, or at the ceiling, may reduce the spaciousness of the sound.
For maximum envelopment the rear speakers should be widely spaced — preferably near the side walls.
Now having made these points, nevertheless I have to conceed that the Harman Kardon users manual recommends not placing the rear speakers over 6 feet from the listener. :confused: Oh well, I guess the manual writers didn't get around to reading Dr.Griesinger's paper. :D

Thanks for your suggestion Sean. I already thought about doing something like that, but I decided that it wouldn't be worth the trouble to make another riser just so there would be one more place to sit. If I didn't make another riser, I would have lost two additional seats that I would have had if I went with my second layout.

You're right. I wasn't sure that it would work either; that is why I put the question mark at the end of my proposed riser dimensions above. Based on my calculations, a 12" riser should work perfect for me, but I made a to-scale profile with just the TV and sofas to make sure.

Looks like it will work. ;)
BTW, the placement of the small heads above the sofas are based on where my head is at when I sit on them (I'm about 5' 11").
