Gypsum board will reflect at least as much as concrete, I'm afraid.

You might want to try angling those surround speakers so that they face more towards the listening area, rather than right at the opposite side walls.

You can install sound diffusor boards on the inside wall (where you brackets are attached). Diffusors look like little cityscapes with a bunch of precisely placed blocks that, together, reflect sound in a random pattern (see here for an example). Cover them with speaker grille cloth (or any acoustically transparent fabric) to make them more aesthetically pleasing. If you use regular fabric the sound won't get a chance to properly reach the board itself. That in addition to Terry's suggestion will help radiate the sound more uniformly into the room and take away the harshness of the concrete's reflection.

I would also strongly suggest you move your main speakers forward in front of the plane of your TV. At least as much as your space will allow. The equipment and such between them right now really eats up any imaging potential.

Good luck.
