The control mount, which attaches to one of the speakers, allows you the ability to control the volume, surround volume, surround balance, as well as subwoofer volume.

Also included with the BA7500 are very nice rear speaker stands, which allow you to place them on the floor behind you in case you do not want to mount them on the wall
