If you are thinking about setting up a home theater with decent speakers, you will probably have to mount them on the wall. I will show you how I mounted my four satellites on the wall. These speakers are from the Logitech Z-5500 set, but nothing in here is too specific to them. I did all of this for less than $5 of supplies.
Step 1: Supplies
Supplies you will need:
four angle brackets
screws that fit in the mounting holes of the speakers
four small rectangular pieces of wood
I used 2" angle brackets from home depot; they cost me $2.89. For the wood, I bought two wooden garden stakes; they were 20 cents a piece at home depot. The wood screws I used for the speakers mounting hardware were $1.49. I am doing this for $4.58. I went to home depot. I am positive that you can do better somewhere else.
Tools you will need:
I used a miter saw to cut the wood because I like a straight cut. Your can use any saw that will cut a small piece of wood. My screwdrivers were a Craftsman 41297 and an electric Black and Decker one. In case you don't know what a try square is, it is a tool that will give you a 90 degree angle from an edge. It is for straight lines and helps a lot with cuts. I used both a pen and a sharpie because although the sharpie is easier to see and writes better, the pen has a sharper line. The vice and pry bar are just one way to bend a metal angle bracket. If you don't have them, imagine another way.
Step 2: Measure and Cut Wood
Take your wood of choice, a speaker, and an angle bracket, and figure out how big your piece of wood will need to be. Mine was 7" long. The speaker holes needed to be 3" apart and the angle bracket holes needed to be 1" away from each other.
The angle bracket holes should be fairly close to the edge of the wood because the wood will be going on the inside of the angle bracket. You will need to have access to the other holes of the angle bracket with the wood attached.
Take in to account the size of your speakers and how close they will be to the wall and gap the bracket and speaker holes accordingly.
After you are sure your holes will allow everything to fit on the board and mount on the wall, carefully measure them out. Do not eyeball them or make them crooked. Use the try square so that your sections of wood are cut straight and so that all of your holes line up with the center of the board.
Do not put your holes too close to the edge of the board. If your holes are too close to the edge, you risk cracking the wood when the screws are screwed in. That will weaken the brace and your speakers may sag or fall.
Step 3: Changing the Angle on an Angle Bracket
The angle brackets are a pain to bend, so put them in a vice and use a pry bar to bend them up. They won't bend nicely at the corner, there will probably be a curve to the bent side. I fixed this by putting the side back in the vice the long way, so that the flat edges of the vice would straighten it back out. If you don't fix the side, thats ok. It might mount a little bit uneven, but you should still be fine.
I chose to bend all of mine about the angle of a green k'nex connector. Once they are attached to the wall, you can use the board as a lever and ease the bracket into a more specific angle if you are unsure of the angle you will need.
Step 4: Almost Ready to Mount
Take a brace and attach it to the piece of wood so that the wood is on the inside of the brace. Now screw the speaker in to the holes you drilled out for it.
This sounds simple, but really, it is not. The brace will attach the same on every board, but the speaker will mount one way for front-right and back-left and another way for front-left and back-right. You can tell how the speaker must be attached by holding it up to the wall where you plan on putting it.
Step 5: Mounting
Use a stud finder to find a stud to drill holes in. Do not screw into drywall alone and do not screw into anything at all similar to drywall without a stud behind it. If you don't use a stud, the brace won't attach firmly enough and will tear out of the wall and fall.
Drill holes for the angle bracket and screw it in. This is hard to mess up. Hold the speaker and brace up to the wall and you should be clear on what angle to place it. I used a sharpie to mark the fake wood paneling in my basement before I drilled, it helps a lot.
I am very happy how my speakers are mounted, it improves the sound greatly and expands the area in which they can be heard. I can't see commercial mounting hardware doing anything to differently except maybe looking different. These do not look bad, they don't look professional but they are not an eyesore.
