So today i finally completed my 5.2 speaker setup. now I have to mount them.

Here's the surrounds I'm using.



They are a little over 2 feet tall, then 13" deep and 12" wide. They weigh 50lbs each.

Here is where they are going to go, to the side of the speaker plates.





There is a stud in the wall about 6-8 inches to the side of each speaker plate.

What I was THINKING about doing was putting some kind of shelf on the wall that sticks out like 15 or 16 inches and then setting the speaker on top of it. That way I can change the angle of it easily if I want to and won't be stuck to 1 position if it is mounted to the wall.

I was thinking possibly getting something like this...

http://www.homedepot.com/p/Everbilt-18-in-x-16-in-White-Heavy-Duty-Shelf-Bracket-14835/202824731?N=bcdr#.UU5a51eHuSp

and then mounting some type of wooden board or shelf to the center of that, then setting the speaker on top of it.

I've just never done something like this before, and I am not 100% sure if that would work or if the wood would teeter/topple when the speaker is placed on it, even if the shelf is bolted to the L bracket thing.

So does anyone think this would work? Or is there any other ideas that someone would recommend over this? I was thinking possibly 2 L brackets but if I had to put them in 2 studs 16" apart, the speaker wouldn't be placed where I would like it to be.

I also wasn't sure if it would be safe if I used 2 L brackets per shelf, and screwed them to the drywall with a drywall anchor.

I've just never done something like this and looking for some advice.

If you can afford it, I'd do something like this:

One possible mount

Or this (only supports up to 33 pounds, supposedly):

Another possible mount

What you are suggesting would also work, but the above would be more hidden.

The other thing is that you might want to point the speakers downward. I had some speakers on the wall that I found were too high. If I stood up, it sounded better than when I sat down. I ended up angling the speakers downward.

I'm not looking to use 2 studs if possible, that will move them to a position that isn't where I really want to put them.

Personally, I would hit both studs, but if you want to try one or both in the drywall, try this link:

Bad idea. The bracket is designed to have all the force perpendicular to the floor. It isn't design to withstand much of a twisting moment.

I would say that mounting a shelf the size you mentioned with a 50# speaker on top to drywall is also a bad idea, especially if there is any chance someone will put any downward force on them. Drywall is not structural. It does OK in compression, but doesn't have much strength in other applications. There are drywall anchors that will handle the weight. They work just fine for something that is close to the wall and pulling straight down. The problem with your shelves is they comprise a big lever trying to pull everything away from the wall. You are going to have to use a big anchor to be sure it won't pull out or through.
