Can L brackets into brick hold a sound bar that's 15 inches out?

Mods, I've made a post about this and it was removed. I've made it more specific as per the rules.

Like the title says, I'm wondering if L brackets can hold weight if the "shelving" is around 15 inches out. I have a TV mounted over a fireplace (I know, I know, but there's no complaints from guests) and no where to really mount the sound bar. It has speakers on the top so I need it to be in front of the TV.

Here are some pictures: https://imgur.com/a/ofH9cGb

The space from the brick to where the mounts on the sound bar would be to be in front of the TV is 15 inches. I was thinking about putting 2 L brackets with 2 pieces of wood to hold the sound bar just far enough.

It'd look like this: https://imgur.com/a/FV3mn9E

I've looked into another option which is buying a bracket so that the sound bar hangs off the TV. I don't want to go that route to avoid adding more weight onto the TV mount.

If thats masonry or cmu, you might need an anchor which should be more than enough to support a sound bar 15 inches away.

How heavy a sound bar? If you can screw into stud, it should be fine.

On the other hand, what about that wood (veneer?) thing across? Can that hold weight? A couple of Z brackets would let you hang off of that?

Sound bar is 8-10 lbs I'd say. I'd be drilling to the brick, not stud.

That's the mantle. I'm not sure if it's solid wood all the way through, the outside texture doesn't feel like totally natural wood. I was thinking of installing reinforcement on that but was wondering it that'd be over-engineering lol.

Really depends on the L brackets. The masonry will hold a static load easily, with a decent anchor. The L brackets will be the weak point. Most that I've seen are nearly symmetrical so they can use thinner material with a strong cross section. It doesn't look like you have that much room under there for the back plate of an L.

I think you'll have trouble finding a decent off the shelf bracket, but it's not a huge deal to fab something.

Brick might be sketchy as it relies on the plugs.

What about hanging the sound bar off of the TV mount? I hanged mine off the VESA plate so that it turns with the TV.
