Question: There are only four mounting holes on my Samsung that will be wall mounted. How do I mound the sound bar to the bottom edge of the TV?
Document: After opening and unboxing I thought of returning it. As another reviewer stated, the sound bar is expected to have screw holes in the back which most don't have. After a little creativity I was able to get it on by using the soundbar's provided wall mounting bracket (Samsung HT-WS1G) and screws+bolts (not provided). I mounted it on an articulating wall mount setup below the display and its not going anywhere.
I used the Sewell Universal Soundbar Bracket to mount my Samsung soundbar below my LED TV. It came with everything I needed to mount the bracket to the back of the TV but I had to go to Home Depot to pick up two sets of nuts and bolts to mount the sound bar's mounting plate to the bottom of the bracket. Once I had everything hooked up, the sound bar stayed in place and hasn't moved since. The bracket felt stable with the sound bar mounted at the bottom of the TV.
Took 15 minutes to use these with a 32&#34; Samsung TV and the Vizio S2920w with the TV still hanging on the wall (using a Sanus full motion mount). The bar hangs nicely below the TV but it couldn't get it perfectly centered (about 1/2 more to one side or the other the way the holes in the bottom are positioned). Perhaps I could have fussed with it more but it's in an exercise room and really doesn't matter.
These work great however for me to have the soundbar closer to the bottom of the TV I need to drill some additional holes since the slots are not long enough. I have these mounted under the TV brackets for the TV wall mount.
I bought this bracket to mount a Samsung HW-F450 sound bar to the TOP of Samsung 60 inch Smart TV. (My TV sits on a credenza.) It stated this can be mounted at the top or the bottom of the TV. NOPE
I received these Brackets today and they came rather quickly, a plus. I mounted them on the bottom on my 42 inch Samsung Flat screen TV. The package comes with about 4 separate sets of screws and a variety of washers. I only needed the screws to use on my Samsung Sound bar because I had screws already being used on the TV's Mount holder.
Once I got this mounted, it holds my Samsung soundbar just fine. It's sturdy enough and the TV is stable. However the mounting bolts that came with it were too short so I had to make a run to the local hardware store. The bolts have to be just the right length to snug the mounts up to the TV, but these weren't. They give you a variety of diameters that should fit any mounting holes, but not my 60&#34; Samsung.
I hung a center channel speaker (not a sound bar) from the bottom of my TV/mount using this product. The TV is mounted to the wall using a articulating mount.I recommend using BOTH screw openings on the long end (lower end in the pictures) to secure it to the TV/mount. Because of the angles involved, I could only use one of these locations. One screw at the speaker, one screw at the TV/bracket.
I thought &#34;universal&#34; meant something like &#34;fits all&#34;...especially it should fit one of the most popular lines of TV's and soundbars in the market place...but boy was I ever wrong.My Samsung sound bar has a unique mounting system which attaches it to a wall, and seemingly they didn't mean for it to attach to a TV.
I have a 47 in TV, which has mounting holes much farther apart than this mount will work. My TV is mounted to a TV stand and the braket on the stand just barely fits the mounting holes. Once I get it mounted to the stand, the sound bar just barely fits below the TV. Also, the hardware included has no nuts, just bots, which do not work when mount to brakets on the TV stand or sound bar bracket.
Answer: Those four holes will be used to hold the bracket for the wall mount.  I mounted the soundbar bracket to the wall mount bracket.  My mount offered ample places to attach with bolt, washer, and nut. My soundbar hangs perfectly under tv.
